A town in Galicia with elevated radon levels

By | News | No Comments

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.

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

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.

Financial support to fight against the silent killer

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.
