Environmental guidance for your business in Northern Ireland & Scotland

Radioactive materials out of scope of the regulations

Radioactive materials out of scope of the regulations

The radioactive materials you keep and use, and the waste that you produce may be classed as “out of scope” of the regulations if the risk to the environment and human health is considered to be negligible.

The level of risk is based on international standards and is set out in numerical values for the concentration of radioactive elements, and the total amount of radioactive material present. The level of risk is calculated by assessing the potential dose that members of the public could be exposed to from the way that radioactive substances are used and disposed of.

What you must do

It is your responsibility to satisfy yourself that the radioactive materials you use, and the wastes that you produce are out of scope of the regulations. You must be able to demonstrate the reasons for your decision to your environmental regulator.

You can find the information you need to decide if the materials you use and the waste you produce are out of scope of the regulations in
