Vintage Illuminated Watches, Clocks and Dials Emitting Radon

By | Blogs | No Comments

In the beginning of the 20th century, scientists developed a way to mix “radium 226” with paint. This created ‘radioluminescent paint’. This breakthrough led to the new product being applied to clocks and telephones. Even airplane instrumentation panels (all now considered to be vintage), enabling the devices to glow in the dark.

However the new approach led to unforeseen circumstances. By 1925 a group of radium painters, later referred to as the Radium Girls, sued their employer over health issues. This was believed to be stemming from the ingestion of radium through a practice called ‘pointing’ their brushes. They would lick the ends of the brushes to refine the bristles into a point. Subsequently ingesting radium remnants from the brush. As a result, by 1930 ‘pointing’ brushes was no longer done by mouth and there were no more incidences of malignancy due to radium. This led most people to believe that radium was not a health risk provided you did not consume it.

Sixty years later researchers from the University of Northampton wondered whether since radium decays into radon gas, “vintage” clocks, watches, phones and such items, previously coated in radium paint could influence radon gas levels as the radium naturally decays.

The study was performed in a small bedroom and consisted of measuring the radon gas level for a baseline. Then adding 30 radium dial watches to the room to see how much the radon level would change, if at all. Upon retesting it was discovered that the room’s radon level rose to 134 times the level at which the EPA (United States Environmental Protection Agency) recommends action.

The data from this first study of its kind indicates a previously unconsidered risk. This was from owning, collecting, and storing radium dial watches or other items coated in radium-infused paint.

So keep calm, and think before you go vintage.

Radon can be a health risk in ordinary workplaces

By | Blogs | No Comments

Workplace radon is a so-called “inert” gas that emits ionising radiation, which means that radon is radioactive. Therefore it is also a potent risk. Ionising radiation can cause damage to cells, which in turn leads to illnesses such as cancer. Lung cancer is the most common form of cancer that can be caused by radon.
Radon gas is an element that can come directly from the ground because radon is created when uranium decays. It therefore exists naturally, which can affect properties that have basements with poor insulation. Or that are otherwise in direct contact with the ground.

How do you know if radon is a health risk in the workplace?

It is easy to measure radon levels in the workplace to see whether the value exceeds the limit above which radon is estimated to be a health risk. If the radon level is above 400 Bq/m³, it could mean that spending too much time in the property entails a direct health risk.

Measuring radon levels is simple and straightforward using radon boxes placed in rooms in which people spend the most time. In the case of homes, they are normally placed in bedrooms and living rooms. In the case of a workplace, it is a question of finding similar places in which people spend a lot of time.

There are two different kinds of radon boxes available: those offering long-term measurement or those offering short-term measurement. Long-term measurement must be carried out during the winter months and needs to last for two to three months to provide the most complete results possible for radon levels in the property. A so-called “annual average value” for the radon levels can be obtained from long-term measurement. There are also boxes that are used to carry out short-term measurements. A measurement with these boxes only takes around 10 twenty-four hour periods. Short-term boxes can be used at any time of year. Nevertheless, the results they give are not as accurate as long-term measurements.

What do you do about high radon levels?

There are a couple of different ways of dealing with high radon levels. One of the most common ways is to simply increase the ventilation to reduce the concentration of radon in the air.

Guide to radon monitoring in the workplace

By | Blogs | No Comments
workplace

Under the EU Radiation Protection Directive, 2013/59/Euratom, which entered into force in February 2018, employers must determine the radon concentrations in the workplace and take appropriate measures to address radon levels above the national limit for radon. With the introduction of the new Directive, questions often arise as to how radon monitoring in the workplace should be handled.

How do we measure radon in workplaces and what should we be considering?

It is basically easy to measure radon. You order radon detectors, deploy them, record data, collect the detectors and send them to the radon laboratory, which will return a report by e-mail or online. However, there are several aspects to consider, such as how many radon detectors are needed for a reliable measurement. Another question is how the work can be done as efficiently as possible. As the biggest cost of radon measurement is the time it takes to deploy the detectors, record the data, and then retrieve them again, it is vital to ensure efficiency and safety at all stages of the process.

Requirements for radon monitoring in a workplace

To make efficient use of time and arrive at a correct measurement, the person monitoring a workplace should make the following demands of the laboratory where the radon detectors were bought. This applies whether you do the job yourself or use an external consultant. Measurements should be taken with radon detectors from an accredited radon laboratory.

Ensure that:

– the laboratory is accredited according to ISO 17025 for measuring radon in indoor air
– the delivery time for detectors is within 2-3 days of ordering
– the delivery time for electronic analysis reports is within one (1) week of the detectors reaching the laboratory
– the laboratory has a web application which allows measurement details to be entered and results to be downloaded, and

  • measurements to be filtered on e.g. address, property name, order code etc.
  • consolidated reports to be downloaded in PDF format
  • can be used on a tablet or other mobile device in the field.

It is also important to make the radon measurements known to your own staff. Information material on radon and the planned measurements should therefore be distributed before monitoring starts. It is also important to inform the cleaning staff if the service is outsourced. The radon detectors need to be placed securely so they cannot be moved or otherwise interfered with during monitoring (cable ties could be used).

How many radon detectors are needed to monitor radon in the workplace?

For radon measurement in the workplace, Radonova recommends following guidelines from IRMA (the International Radon Measurement Association). You will then meet your national requirements as well. The advantage of IRMA’s guidelines is that their recommended measurement procedure helps to save time.

The following locations must be included when measuring radon:

– Rooms and locations regularly used for more than four hours per day
– All underground/basement locations or other locations used by anyone for more than 50 hours per year where there is a risk of radon leakage
– Any relevant locations/rooms at basement and ground floor level. In larger spaces, deploy at least one detector per 150 m2.
– On higher floors: At least two detectors, and at least one per 250 m2.

What happens if you are over the reference value?

If it turns out that you are over the reference value, you should start by measuring the radon concentration during working hours (a shorter period). You could do this with Radonova’s Duotrak radon detector, for example. Note: Because work premises are usually ventilated more during working hours, the radon level could be lower at this time.

If the workplace is still over the reference value, you must take steps to reduce the radon level. This is normally done by controlling the ventilation. In these cases, however, we recommend contacting a radon consultant who can investigate where the radon is coming from and suggest appropriate action.

Radonova launches brand-new vacuum packs for radon detectors

By | Okategoriserade | No Comments

Radonova are launching a new vacuum packaging solution.

The new packaging enables us to vacuum seal radon detectors during transit which helps us to improve quality even further. This ensures safe transit and analysis can be done without radon leakages. The packaging technique will help prevent damaging effects from external factors on the measurement results.

With radon monitoring it is crucial to be able to seal the detectors to ensure the test results are reliable.

Vacuum packs enable more efficient transport and storage

“In addition to being completely radon-tight, the new vacuum pack is smaller. This means less bulky shipments and more efficient storage. This particularly benefits our distributors and international customers. Of course the new packaging also has environmental benefits as it uses less material. Another advantage with the new packaging technique is that bags damaged in transit can easily be spotted”, explains Radonova’s laboratory manager, Oscar Wännerud.

“We have always used very high quality plastic films but by using our new machine and a more automated process it means we are now taking a further step towards the optimum packaging solution” says Wännerud.

WHO estimates that up to 14% of all lung cancer cases are caused by radon. Find out more about the risks associated with radon and how to measure it here.

Radonova’s radon measurements get top marks from Europe’s leading radiation protection body

By | News | No Comments

Radonova Laboratories has achieved excellent results in reference tests.

The reference tests were finally conducted by the German Federal Office For Radiation Protection (Bundesamt für Strahlenschutz – BfS). Comparative tests of four different radon samples show us that Radonova’s results in all cases differ. This with less than ten percent from the respective reference value.

The BfS is Europe’s leading player in the calibration of radon measurement equipment. One of the few accredited to calibrate based on ISO 17025 standard.

All radon doses are exposed to different levels of radon in this current reference tests. Then after that they are compared with the official reference values that are specified by BfS.

“Radonova has consequently been participating in comparative tests of this kind for many years, and we achieve consistently good results. The latest test results are also a confirmation that we are right at the forefront when it comes to reliable radon measurements”. Says the CEO of Radonova Laboratories, Karl Nilsson.

reference tests

“The comparative tests by the Bfs are probably the most demanding anywhere. They certainly set extremely high standards at all stages. It feels good to have our capacity confirmed by an actor like BfS. It is important that our customers should always associate Radonova with the highest quality and reliability”.

Radon Workshop – Radonova’s measurement expert attends IAEA meeting

By | News | No Comments

Radon issues call for international coordination

As part of the work of improving coordination and contributing to more uniform processes for analysing and measuring radon, the IAEA recently organised a radon workshop in Sarajevo. José-Luis Gutiérrez Villanueva from the Swedish company Radonova was present as a specialist in radon measurement. We put some questions to José-Luis, who is one of Europe’s leading experts in this field.

Why is a radon workshop of this kind significant?

Its an important forum, this meetings. We can study all findings from different countries and can share them with others. It is also an important meeting-place for those countries that are not members of the EU and hence covered by EURATOM BSS but are in the IAEA and covered by IAEA BSS. In that sense, the IAEA radon workshop gives us a broad and effective platform for exchanging knowledge.

In what way is it important to have an international perspective on the question of radon?

By looking at this from a global perspective, we can see the differences in the way various countries handle the problem of radon. Although there are international guidelines and regulations.  There are big differences in the work done and the radon programmes in different countries. A radon workshop meeting of this kind helps us to exchange knowledge. Also to reach a common understanding of how best to approach the work. In this case, we were particularly interested in how databases and analyses of statistics from different studies can be used.

What would you say is the biggest challenge if we look at radon as a global problem?

One of the major challenges is how to communicate around issues concerning radon in general and the risks in particular. The differences in priorities and judgment of risk areas are one example. Different countries can arrive at different risk assessments and classifications even though the geological conditions are basically the same.

Radon workshop

José-Luis Gutiérrez Villanueva has worked on radon issues and radon workshops for the last 15 years. He wrote his PhD on ‘Radon exposure in dwellings of lung cancer patients: case-control study’ (University of Cantabria, 2016), and is an expert in 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 .

IAEA is short for the International Atomic Energy Agency. BSS stands for Basic Safety Standards.

The title of the event held in Sarajevo from 12-14 June 2018 was ‘Regional Workshop: on database and statistical analyses, harmonisation of protocols and procedures for the measurement of radon’.

Global study confirms the harmful effects of radon

Global study confirms the harmful effects of radon

A study based on data from 66 countries and presented in Environmental Health Studies (EHP) confirms that there is a clear link between exposure to radon and the risk of lung cancer. Updated data from 2012 show that around 226,000 people died that year from radon-related lung cancer. That means that about three per cent of all those who die from some form of cancer do so because of radon.

“After smoking, radon is therefore the commonest cause of lung cancer. It makes radon a serious global health problem that we must combat with knowledge and modern technology. This says Karl Nilsson, CEO. for Radonova Laboratories.

“We can now detect and deal with many of the harmful levels of radon. But most importantly we need many countries to take the issue of radon more seriously. Sweden and the US are relatively far ahead in combating radon exposure. However, other parts of the world have not begun to take the necessary steps to reduce the health risks and fatalities,” says Karl Nilsson.

The study is presented in issue no 5 (2018) of EHP and can be accessed here » ehp.niehs.nih.gov/EHP2503

Matrasses have high levels of radon gas in Korea

By | News, Okategoriserade | No Comments

Korean radioactive beds matrasses

A recent news published in a Korean newspaper has drawn international attention: bed matrasses may be a source of radon gas

The radioactive Korean matrasses

In May 2018, the Korean government confirmed high levels of radon gas exhalation in some beds. Due to that, some beds could be a source of radon gas.

Are matrasses dangerous?

First investigations found out that exhalation levels were 10 times higher than the reference level. Radon gas is the second leading cause of lung cancer after smoking. Therefore, beds caught the interest of Korean authorities.

What’s next?

Consumers associations have started actions in the court against the company. In addition, the Korean government has withdrawn all matrasses and asked for expert advice.

A town in Galicia with elevated radon levels

By | News | No Comments

galicia Costa da morte

A small town in North-western Spain has cancer cases 7 times higher than the Spanish average. The town is located in A Coruña, in the Autonomous Region of Galicia. Furthermore, this region has very high radon levels.

A little town in Galicia: facts

This town has 313 inhabitants and the cancer cases account for 23 only on an 800 m road. Also, the rest of the location has a big incidence of cancer.

Why?

This region is one of the Radon Priority Areas in Spain. As a result, the high number of cancer cases in this town might be attributable to elevated radon levels. Other public buildings in Galicia have similar radon-related problems.

Available tools

The EURATOM BSS 59/2013 Directive establishes a reference level for radon of 300 Bq m-3and mandates member states to set up national radon action plans.

Questions and answers about radon in water

By | Blogs | No Comments

SSM (The Swedish Radiation Safety Authority) has recently published the National Radon Action Plan. Radon in drinking water has been highlighted as one of the risks. As the world’s leading radon laboratory, Radonova Laboratories AB gets a lot of questions about water safety. Below you can find some answers to the most common inquiries we receive on this subject.

Can we find radon in drinking water?

Radon in drinking water can occur primarily in water from wells bored down through solid rock. In Sweden, wells supply water to approximately 800,000 people. More than 6% of these wells are estimated to have such high levels of radon as to be hazardous to health. This means that radon concentrations in these waters may exceed the limit of 1000 Bq l-1, while 60% of wells are in the range of 100-1000 Bq l-1. There is also a risk of elevated radon levels in water wells bored down through soil layers. Data from the SGU (Swedish Geological Survey)shows that 1.6% of these wells are above 1000 Bq l-1and 30% in the range 100-1000 Bq l-1.

How dangerous is radon in water?

Radon in water can be harmful to health in two ways. Firstly, by radon adsorption during and after water intake and second, by radon release from water into indoor air that we breath. Radon from the air is significantly more dangerous because our lungs are more sensitive to radon compared to the stomach. As we now know, radon breaks down over time into radioactive isotopes we call ‘daughters’ with the emission of alpha particles causing lung tissue damage. Thus, high levels of radon can lead to lung cancer. Radon causes about 1100 lung cancer cases per year in the UK according to PHE (Public Health England).

How can you measure radon in drinking water?

It is easy to measure radon in water. After ordering a measurement pack from our website, we will send a kit containing a special bottle with clear instructions on how to take the water sample. Once you have filled the bottle with water, send it back to us. The analysis results will be obtained within one week. All Radonova’s measurement methods are accredited by SWEDAC, which means that you can rely on our results.

Swedish Radon action plan

By | News | No Comments

The new national plan for radon in Sweden has been issued in April 2017. This plan is the result of a joint effort of seven central government authorities. The plan mandates the Swedish Radiation Safety Authority to coordinate the work of all the authorities to reduce the radon exposure to the population in Sweden. The reference level is 200 Bq m-3 and you can find further information on the website of SSM. The document (in Swedish) can be downloaded at this link

Radon as tracer and global climate research

By | News | No Comments

© Asya M – stock.adobe.com

We used to consider radon as the second leading cause of lung cancer. This has been proved by means of many studies and research projects. However, radon can be used as a tracer too. One example is an investigation carried out in Antarctica to look into how the relationship between pollutants reaching Antarctica and global climate models. What stands out from this study in terms of radon metrology is the device developed by Australian Nuclear Science and Technology Organisation (ANSTO). Have a look at the published paper to observe the very low values this instrument is able to measure. It can measure mBq m-3. For further information check the article published on phys.org.

metroRADON: Metrology for Radon monitoring

By | Blogs, Okategoriserade | No Comments

Why do we need this project?

On 6th of February 2018, all European member states have had to incorporate into their national legislation the new EURATOM Directive 2013/59. This is a milestone to protect people against the dangers coming from ionising radiation and, in particular, those from radon exposure. Therefore, there are new needs in terms of calibration of radon measuring devices and protocols dealing with radon measurements. Also, as the Directive states the reference level for radon concentration must not exceed 300 Bq.m-3 so the challenge of having traceable and good calibration sources becomes obvious.

Structure and work packages

The project is funded by EMPIR (European Metrology Program for Innovation and Research) and coordinated by BEV/PTPmetroRADON has five main objectives:

  • To establish calibration procedures for measuring instruments capable of detecting low radon concentrations
  • To look into how thoron concentrations may affect radon measurements
  • To revise the existing radon measurement protocols in Europe and enhance such practices all over the continent
  • To provide support for the implementation of the new Directive in terms of the definition of RPA (Radon Priority Areas)
  • To revise the existing radon calibration facilities in Europe

Apart from the above, there are other objectives in terms of dissemination of results and enhanced communication that make metroRADON a very ambitious project that will be running for the next 3 years.

Partners

There are 17 partners involved in the project. Eight of them come from national metrological institutes and the rest are from research centers and universities. The following countries are represented: Austria, Bulgaria, Czech Republic, Finland, France, Germany, Hungary, Romania, Serbia, Spain and Switzerland. The European Commission is represented by the JRC (Joint Research Centre). In addition to that, 25 companies compose the Industry Interest Group and among them, Radonova laboratories AB from Sweden are an active participant.

Timeline

The project will extend from June 2017 until June 2020. Every six months a newsletter will be issued showing progress and upcoming activities. All the information is available on the website www.metroradon.eu

Financial support to fight against the silent killer

By | News | No Comments

Last February 2018, the 28 EU member states had to implement the EURATOM BSS 59/2013 Directive into their national legislation. An interesting part of this document is the Annex XVIII with a list of 14 items to consider by the governments during the design of the national radon action plans. The item 12 says “Where appropriate, provision of financial support for radon surveys and for remedial measures, in particular for private dwellings with very high radon concentrations”. The Swedish and Spanish governments are an xample of this. As of 1st July 2018, homeowners can receive up to 25000 SEK to reduce the radon levels indoors. But before doing this, radon measurements must have been done using the services of an accredited laboratory as it is the case of Radonova Laboratories AB. In Spain, the national building plan includes in the Art. 36 the possibility of providing financial support to reduce radon levels below 300 Bq m-3.
