Information about radiation and its effects, and information on radon in the home
Radiation
Radiation occurs from two sources:
- natural radiation exists due to materials present in the earth, and particles arriving from outer space
- artificial radiation is caused by man-made processes
There is no difference in the effects of the radiation from either source.
We are exposed to a low level of radiation throughout our lives. This is perfectly normal and does not cause any health effects. However, large amounts of low radiation over a long time can cause health problems.
Radiation monitoring
Until 2016 we carried out radiation monitoring to establish normal background radiation levels. The results can be used in assessing and managing nationwide consequences of a nuclear incident, such as the one that occurred at Chernobyl in 1986.
Following the Chernobyl incident in 1986 a nationwide nuclear radiation monitoring network called RIMNET was introduced. RIMNET has monitoring sites located across the country and is managed by the Met Office.
The radiation monitoring measured normal background radiation levels. If an incident should happen the monitoring results would assist in the recovery.
Radon
Radon is a naturally occurring radioactive gas which can come from soil. It can sometimes build up inside homes.
The UK Health Security Agency (UKHSA) have released an updated radon potential map, produced by UKHSA and BGS. This is the first update in over 10 years. The potential map assesses the likelihood of a building being in a Radon Affected Area. The map shows that some areas in the borough may have radon levels at or above the action level.
The UKHSA recommends that individuals and employers check the map to see if a radon test is advised in homes and workplaces in their area. Further information can be found on the UKHSA UKradon website
If a test shows that a property has levels of radon above the action levels, you may need to consider ways to reduce this. Further information on techniques to reduce levels is available on the UKradon website.
