Radon mitigation measures

If radon levels of over 100 Bq/m³ have been measured in your residence, radon mitigation measures should be implemented in order to reduce these levels.

There are both artificial and natural radioactive substances in our food.

The nuclear action plan

The nuclear action plan aims to reduce the risk of serious accidents and radioactive contamination, and to prevent nuclear and other radioactive material from going astray.
