ATMOS: New version of the world’s lightest and most sensitive radon sniffer

By | Measurement, News | No Comments

Radonova Laboratories is launching a completely new version of the radon sniffer ATMOS. The new version weighs 4.5 kg , has a new design, several new features and enhanced software functionality. The new ATMOS is designed to enable even faster and more efficient radon measurements in the field. The latest version of ATMOS is now commercially available.
The instrument has been developed to meet the needs of an international market that is growing and demanding modern, user-friendly instruments for radon measurement.

Increased demand for radon measurement

The need for reliable and flexible field instruments has increased as more and more homes and workplaces show increased levels of radon.
In the case of a radon inspection, the user normally searches for the leakage of radon and therefore needs an instrument that can quickly display the correct radon content. Therefore, there is sometimes a need to measure the variation of radon every minute and in various contexts to clarify daytime variations. In this circumstance, ATMOS makes the radon consultant’s everyday life easier and more efficient.

Fast and reliable measurement reports

ATMOS is unique because it is the most sensitive and lightest instrument that can be used both in the field and in a laboratory.
– Thanks to its light compact format and general portability, ATMOS can easily be taken out for radon inspection of properties. The updated software makes it very easy to extract data and quickly create reliable measurement reports. The latest version of ATMOS enables radon consultants to conduct considerably more measurements compared to other instruments on the market in a 24 hour period, says Patrik Starck, technical physicist and Radonova’s development manager.
– Compared to previous versions, the instrument has essentially been completely redesigned. The only part that remains is the measuring chamber. That particular part is based on a proven technique and it is doubtful whether you can improve the design, continues Patrik Starck.

Growing international market

Previous versions of ATMOS have mainly been delivered and used in Sweden. With increased international demand, Radonova has scaled production at the company’s plant in Uppsala.
– It is of course gratifying when we now see clear demand outside Sweden. The new ATMOS has been launched after several years of research and development. The positive response from the market is an acknowledgment that more and more people and businesses are seeing the benefits of the instrument, comments Karl Nilsson, CEO, Radonova Laboratories.

New ATMOS specifications:

  • Light and compact, simplifying field work
  • Weight: 4.5 kg Size: 500 x 385 x 220 mm (W x H x D)
  • New software enables fast and secure measurement reports
  • The pulsation chamber has high sensitivity and a fast response time
  • Chirp function – listens to how high the content is in confined spaces
  • Communication to PC via USB
  • > 10 year history for measurement data

The basic version of ATMOS costs SEK 89,450 excluding VAT.

Risks with radon

Radon is a radioactive gas that forms naturally when the substance Uran238 decomposes. Thereafter, the radon gas, in turn, decomposes into radond daughters. Radon daughters are radioactive metal atoms that get stuck in our airways during inhalation. When this disintegration occurs, radiation is emitted from the radon daughters that can damage the cells in our airways and lungs. In the worst case, they can cause cancer. According to the World Health Organization (WHO), 3-14 percent of all lung cancer cases are caused by radon depending on where you live. Therefore, WHO recommends a radon level limit of 100 Bq/m3.

ATMOS product description

ATMOS has a built-in dehumidification to ensure that the moisture content of the air does not interfere with the measurement. The dehumidifier works in saturated moisture at temperatures up to 40ºC. 40 degrees C. ATMOS also shows a table of the 10 latest measured levels per selected integration time. To each calculated radon measurement the user is presented with the associated uncertainty in measurement. The dehumidification of the air in ATMOS takes place automatically and is fully integrated in the instrument. The atmospheric pressure, temperature and humidity of the air are shown in the display and stored together with each measurement. Due to the fact that the measurement value is displayed directly at a new measurement, the user does not have to wait for the end of the measuring cycle.
ATMOS includes software for analyzing measurement data. The display is a 3.5 ? touch screen that shows the radon content in Bq/m³, the uncertainty since the start time of the measurement, integration time, measurement time, time and date. In addition, a field storage bag with detachable lid, 24VDC mains adapter and 3 meter hose with instrument adapter are included. The readout and reporting software works in Windows and is included with the instrument. The software is used to read out stored measurement data to evaluate time variations and energy spectrum. In addition, the software is compatible with older versions of Windows.
The instrument measures the alpha decay of radon and its daughters and is completely insensitive to gamma radiation. The alpha energies of the different isotopes are detected and the radon concentration is displayed in a touch display on the instrument. The user selects the desired integration time, the longer the time the more accurate the measurement. The measurement energy spectrum is stored every 10 minutes during the measurement and always gives the user the opportunity to quality-assure the measurement data. A measurement value is displayed directly at a new measurement and the user does not have to wait.

Radiation measurement: from timber to wild boar

By | News | No Comments

Radonova’s story begins in 1986 when a group of researchers at Uppsala University in Sweden were commissioned to measure the radioactive fallout from the Chernobyl accident in Sweden and beyond. Today the company focuses primarily on radon measurement, a field in which we are the global leader.

Each year, though, Radonova also carries out a large number of radiation measurements on everything from wild game meat to timber. Our customers are authorities, private individuals and companies.

“Although our core business these days is radon measurement in homes and other premises, we regularly carry out other forms of radiation analyses. We have so far conducted around half a million analyses, in addition to radon measurement,” comments Oscar Wännerud, a laboratory manager at Radonova Laboratories.

Participated in several wildlife projects

Over the years Radonova has collaborated on projects with a number of authorities and organisations. Radonova also performs caesium analyses for customers in Europe and Asia.

“A lot of our analyses have involved reindeer meat and have been commissioned by the Swedish Board of Agriculture and more recently Sametinget (the Sami Parliament). We have also carried out a large number of measurements on wild boar meat and have participated in the Swedish Radiation Safety Authority’s project offering free measurement of caesium-137 in meat from wild boar,” continues Oscar.

Radiation levels can be high in wild boar because the animals root for food and consume berries, mushrooms and roots or other foodstuffs that have lain in the soil for a long time. The wild boar also ingests a lot of soil that may also contain caesium-137.

Easy to carry out radiation measurement

Like radon measurement, radiation measurement of foodstuffs and other items is often relatively simple. “Generally speaking, it is easy to order and submit a sample of foodstuff for radiation measurement. Over the years we have received a lot of foodstuffs, including wild game meat, mushrooms, berries and fish, as well as some more unusual items, such as a tree stump, a cot, lynx testicles, vodka, snus and cigarettes. These are items you wouldn’t normally associate with radioactive radiation. When it comes to foodstuffs and items that are in close proximity to people for a prolonged period, it is, of course, prudent to conduct a measurement. Especially when you consider that exposure to radiation can have serious consequences and increase the risk of cancer,” concludes Oscar Wännerud.

British Columbia Lung Association to Provide Radonova’s Test Kits for Home, Workplace and School Radon Monitoring

By | Measurement, News | No Comments

Through its partnership with Radon Environmental, the British Columbia Lung Association (BCLA) is providing Radonova’s radon detectors to consumers to offer a fast, efficient, and accurate way to find out if your home, school or workplace has potentially hazardous indoor radon levels. The detectors supplied by the BCLA gives the public the option of choosing either a short or long-term test kit. All test kits provided are recognized by Health Canada and C-NRPP certified. This news follows on from The Lung Association – Ontario also announcing that it would be offering Radonova’s state-of-the-art radon monitors to the general public.

“The air you breathe, regardless of where you live or work, is important to your health. The BC Lung Association is committed to protecting your breathing and that’s why we are excited about being able to offer a variety of radon test kits for the public,” said Christopher Lam, President & CEO of the BC Lung Association.

The two alpha track radon detection devices the BCLA will be making available to the public are Rapidos and Radtrak². Rapidos is a short-term radon measurement test kit that captures a measurement of radon levels over a 10-30 day period. Measurement reports are available from Radonova’s laboratory within 1-2 weeks after the laboratory has received the detectors.

Both accurate and flexible, Rapidos is one of the most effective and flexible ways to measure radon in residential buildings, workplaces and schools.

Radtrak² is Radonova’s flagship long-term radon test kit and tests home’s and workplaces for radon over a sustained period, as encouraged by Health Canada. With ultra-high accuracy over a prolonged period of time, it provides a full and clear perspective on the risk of radon exposure in the tested location.

Radon is an invisible, odourless and tasteless gas that can accumulate to unnaturally high and dangerous levels in homes and workplaces. Young people and children are more vulnerable to radiation as they have higher respiratory rates than adults. However, consumer knowledge on how to detect Radon and meaningfully reduce exposure is still relatively low.

Bill Rounds, President at Radonova, said: “Our work with the various Lung Associations in Canada highlights that the general public and businesses are gradually becoming more aware of the dangers of radon. Radon is a global health problem that is estimated to cause 230,000 cases of lung cancer each year¹. A recent report by the World Health Organization states that radon should be regarded as a carcinogen on a par with tobacco smoke². The technologies we offer ensure customers are receiving a reliable, high quality measurement that will aide in helping individuals make decisions about their home’s indoor air quality. Living with high radon is truly an unnecessary health risk. Elevated radon levels in the home can easily be reduced, but you have to test to know.”

Radon Environmental President & CEO, Alan Whitehead commented: “We’re delighted to have expanded our Radon Testing Device and Service Agreement with the British Columbia Lung Association, to provide our extended range of Radonova short term (Rapidos) and long term (Radtrak²) alpha track radon detection devices. We supply many local health authorities and public testing initiatives across Canada and our partnership with the BCLA will lead to increased public awareness and radon testing in British Columbia. Radtrak² has the largest range of detection of any alpha track device and the Radonova laboratory is the only ISO17025 certified alpha track testing facility of its kind, so our clients can be confident in the lab analysis and its QA process. One of the features that our clients like the most is RadOnline, Radonova’s online customer portal. Through MyPages, customers can easily input measurement data, retrieve reports, and have an overview on every project, in real-time.”

Intercomparison test: Radonova receives high marks from PHE

By | Measurement, News | No Comments

Radonova Laboratories has achieved outstanding results in a preliminary comparative reference test performed by the state-owned PHE (Public Health England). The intercomparison tests were performed at five different radon levels – Radonova participated with two different types of detectors for each exposure. In all ten cases, Radonova’s results differed by less than 4% from the respective reference value.
During the reference test, radon detectors were exposed to different levels of radon. The results are then compared to the official reference values as dictated by PHE. Radonova’s detector Duotrak had a particularly small deviation where three out of five tests deviated by less than one per cent from the reference value.

Demanding test

“For several years, Radonova has regularly been involved in this type of comparative reference test. We are consistently given high marks but are still very pleased by the fact that this is probably our best result so far. It feels particularly good when we are constantly working on developing and refining our radon detectors as well as instruments and measuring methods,” said Radonova Laboratories CEO, Karl Nilsson.
“PHE’s comparative reference test is among the most demanding in the industry. It tests both low and high exposures which places particularly high demands on reliability. We are always looking to offer our customers the highest quality technology and take this as an acknowledgment that we continue to be at the forefront of the market for radon measurements,” comments Bill Rounds, President of Radonova.
The radon detectors were subjected to exposure between 137 – 2180 kBqh/m3. PHE is expected to publish the report towards the end of 2019.

Canadian radon project chooses Radonova for analysis of radon samples

By | Measurement, News | No Comments

Swedish Radonova Laboratories has been commissioned to analyse radon samples in the major Canadian campaign “Evict Radon”. This campaign aims to reduce the incidence of radon in Canadian homes and lung cancer as a consequence of long-term exposure to radon gas. This campaign being conducted in the province of Alberta is headed by Dr Aaron Goodarzi at the University of Calgary.

Radon is measured for at least 90 days and analysed at Radonova’s laboratory. The results will form the basis for continued studies on how radon exposure affects the environment and the health of residents. The project involves doctors, biologists, geologists, architects and experts from a number of other fields. It is estimated that in parts of the province of Alberta, one in six homes is affected by radon. Moreover, every day one resident is diagnosed with lung cancer caused by radon.

May become a template for similar projects

“We are naturally proud that such a large and important project has chosen Radonova as its partner for analysis of its radon measurements. At the same time, we know that Radonova is the only operator with global ISO certification. We currently occupy a very prominent position when it comes to radon measurement and analysis. In this role we always want to play an active part in the work of reducing unhealthy exposure to radon. The Evict Radon campaign seems particularly important, as it is comprehensive and well planned. This means in turn that after the campaign has ended it can act as a template for similar projects,” says Karl Nilsson, CEO of Radonova Laboratories.

After smoking, radon is the most common cause of lung cancer. This makes radon a serious global health problem that every year leads to around 230,000 cases of lung cancer.

Radon as a health risk – WHO report

By | News | No Comments

The WHO’s latest report ‘Guidelines on Housing and Health’ describes how people’s housing and health are affected by a variety of factors. The report describes radon, among other factors, as a health risk. It draws attention to the fact that radon should be regarded as a carcinogen on a par with tobacco smoke.

The harmful effects of radon are emphasised by, among other things, the WHO wanting to reduce the reference level for radon in home environments to 100 Bq/m³. That is one-third of the reference level established in Directive 2013/59/EURATOM, which is 300 Bq/m³.

Radon causes lung cancer

Radon as a health risk is a global problem that each year is estimated to cause around 230,000 cases of lung cancer, which has a high mortality rate. Radonova’s measurement expert José-Luis Gutiérrez Villanueva comments on the latest WHO report:

“It is important that radon is not singled out, but regarded as one pollutant among many. In this respect, the WHO’s report is clear and important. The report describes the harmful effects of radon, as well as how preventive measures can be used to reduce harmful radon levels. Bearing in mind the fact that radon causes a very high number of lung cancer cases, it is vital to speak plainly about this issue.

“While radon is a global problem, the WHO’s report makes it clear that radon needs to be tackled at national level. In order to be effective, each country needs a well-developed programme that can be adapted to the circumstances in each case.”

José-Luis Gutiérrez Villanueva has worked on radon issues for the last 15 years. He wrote his PhD on ‘Radon concentrations in soil, air and water in a granitic area: instrumental development and measurements’ (University of Valladolid, 2008), and is an expert in areas including data analysis and different ways of measuring radon. As secretary of the European Radon Association, José-Luis also has extensive experience of international work with radon.

Radon maps don’t show radon levels in a specific building

By | Measurement, News | No Comments

‘Radon maps’ is a term that frequently crops up when talking about the risk of radon. A radon map provides a general picture of the areas where there is a risk of high radon levels. These maps are available at both national and regional level. The problem with radon maps is, however, that they are a very blunt tool for anyone wanting to find out about radon levels in a specific building.

Despite this, Radonova is seeing a growing number of cases where private individuals and workplaces are using radon maps to try to determine the radon level in their specific indoor environment.

“Radon maps are designed to be used when you want a more general geographic breakdown of low-risk and high-risk zones. It is, however, very difficult to draw any reliable conclusions from these about radon levels inside a particular building,” comments Karl Nilsson, CEO of Radonova Laboratories.

“The relevant authorities and experts often have good knowledge of the applications for which radon maps can be used. Problems tend to arise when the general public draw conclusions from the maps about radon levels in their own home.”

This is why radon maps do not show radon levels in a specific building

Below are some of the reasons why radon maps are not a reliable tool for determining radon levels in a specific building.

Radon maps do not show local variations

When producing a radon map, very few measurements are performed per square kilometre. Radon levels can vary significantly in such a large area and also markedly between buildings on the same street. Radon levels indoors largely depend on the building’s construction and the air permeability of the soil, which can vary widely locally.

There is no standard for the production of radon maps

To produce a radon map, measurement data is either obtained by measuring ground radon levels or using data from indoor measurements in the area. With ground radon measurement there is no clear link between the level of radon in the ground and indoor radon levels. There is certainly an increased risk with high ground radon levels, but other factors, such as construction technology, can have a greater impact. However, if the radon map is based on indoor measurements, then the results are therefore heavily dependent on the type of building structure where the measurement was recorded. This in turn need not be relevant in any way for another building close by.

Radon can be emitted by building materials

In a country like Sweden the use of blue lightweight concrete is a clear example of how a building material comes into play when measuring radon levels. In Sweden around 15 per cent of all elevated radon values are caused by blue lightweight concrete. A radon map, however, does not take into account the material used in a building.

The maps can be generated from old measured values

Measured radon levels are to some extent ‘perishable’. A measurement taken 15 years ago, for example, is no longer reliable. A lot may have happened over the years in and around the building in question to change radon levels. Modernisations, changes to ventilation and groundwork are just a few examples of factors that can have a major impact on indoor radon levels. The Swedish Radiation Safety Authority recommends performing a new measurement every 10 years.

“With this in mind, you shouldn’t rely on radon maps if you want to know what the radon levels are in a specific building. Even if you live in an area that is defined on the radon map as a low-risk zone, there may still be very high radon levels indoors. Given that radon, after smoking, is the most common cause of lung cancer, there is every reason not to rely on this type of map when trying to determine radon levels in the home and at workplaces,” concludes Karl Nilsson.

Measure in the building

The only way to get a reliable picture of radon levels in indoor air is to measure them. This can be done in an affordable manner using radon detectors. Radon maps still have a role to play, however, as they can provide the authorities with an overview that makes it easier to prioritise inspection efforts.

COIRA chooses radon detectors from Radonova for major international study

By | Measurement, News | No Comments

Radonova Laboratories will be providing radon detectors to a major international study to be run by COIRA (the Coalition of International Radon Associations). The aim of the project is to compare radon measurement results obtained by the world’s leading monitoring institutions in the field of radiation protection. The project started in August 2018 and will run for two years.

“This is a very important project. It will help us towards a more consistent way of working and greater precision in our work on radon measurements. COIRA provides a forum for the collective global expertise on radon. We are pleased to be an active part of this forum in terms of both measuring equipment and knowledge,” says Karl Nilsson, a member of the board of COIRA and CEO of Radonova Laboratories.
coira

Radonova’s radon specialist José-Luis Gutiérrez Villanueva is a member of the project committee. He is there as an expert and representative of ERA (the European Radon Association), one of the project’s scientific coordinators (COIRA). Gutiérrez Villanueva is also involved in the work of analysing the data collected.

“Such a comprehensive comparative study means that we can expect to have access to reference tools within a few years.  This will make radon monitoring safer and more effective,” he explains.

COIRA was formed in 2015 and has five member associations: ERA (the European Radon Association), AARST (the American Association of Radon Scientists and Technologists), CARST (the Canadian Association of Radon Scientists and Technologists), UKRA (the UK Radon Association) and NGRA (the Nordic Group of Radon Associations).

Finland ahead of the rest of Europe

By | News, Workplace | No Comments

-Radon measurement in the workplace is commonplace 

It’s not just in school education that Finland is ahead of the rest of Europe. When it comes to measuring radon in workplaces, they are a step ahead there too. Measuring radon in Finnish workplaces has been commonplace for a number of years for Radonova’s partner Suomen radonhallinta.  

Even before the new Radiation Protection Act was introduced on 1 June this year, the Swedish Work Environment Authority imposed the requirement that the hygienic limit value for radon (0.36 MBqh/m3) must not be exceeded in Swedish workplaces. And yet there were only around 3,000 instances of workplace measurement in Sweden during 2017, compared with around 70,000 instances of measurement in homes. In the rest of Europe also there is less workplace measurement compared with measurement in homes.

“It is hard to say exactly how much workplace measurement we have performed, but it is well into the thousands. Then of course there are several other operators also measuring radon in workplaces. In Finland there are around 60 high-risk areas where employers are obliged to measure radon in the workplace. Considering that radon is reckoned to cause lung cancer in 300 to 400 Finns every year, there is of course every reason to comply with the existing regulations,” comments Jarkko Ruokonen at Suomen radonhallinta.

Common cause of lung cancer

“Although we are seeing increased demand for workplace measurement this year, it is clear that a lot of workplaces will not manage to comply with the new legal requirements. Here it seems as if Finland has been quick to take the radon issue seriously. Just as in the rest of Europe, radon is, after smoking, the single biggest cause of lung cancer in the population. If we are to bring the figures down, greater efforts are required, as is cooperation between employers, public authorities and private operators,” comments Karl Nilsson, CEO of Radonova Laboratories.

“If you haven’t already taken radon measurements at your workplace then it is high time you did so. Quite apart from the fact that as an employer you are risking exposing your employees to a serious health hazard, there can be serious repercussions for employers who do not comply with the law. Here I absolutely think that the rest of Europe should be aiming to take the radon issue at least as seriously as Finland does,” concludes Karl Nilsson.

Finland

Jarkko Ruokonen at Suomen radonhallinta measures radon at a workplace in Finland. “Our cooperation with Radonova is going really well. They have a modern lab that is certified in accordance with ISO17025, reliable products and excellent customer service.”
