Radiation monitoring

The naturally occurring radioactive gas radon, arises from the decay of natural elements in rock and soil. Levels indoors depend on a number of factors:

  • the concentration of radon in the ground
  • the way a house is constructed
  • the way the house is heated and ventilated

Long term exposure to high levels of the gas has been found to cause lung cancer, especially by those people who smoke where radon is found to be more common.

Radon affected areas

There are parts of the country where 1% or more of properties are estimated to be above the UK radon action level of 200 becquerels per cubic metre of air.

Visit The UK Health Security Agency (UKHSA) website to view maps on radon.

Measuring radon levels

Every building has radon and in most areas the levels are low. Through UKHSA website Welcome to UKradon you can:

  • order a radon address search
  • order a home measurement pack
  • order a workplace measurement pack

More information on measuring radon can be found on UKHSA website.

Other radioactive substances

Nuclear sites and other industries can create radioactive waste as a result of their routine operations. Some of the wastes are released into the air or discharged to water, the radioactivity can enter the environment and access the food chain. The releases and discharges are controlled by authorisations issued by the Environment Agency. The Environment Agency (EA) and the Food Standards Agency (FSA) separately monitor levels of radioactivity in the environment and food chain.
