Notify HSENI of work using ionising radiation

Every employer is required to notify HSENI of low-risk work that they carry out with ionising radiation or in an atmosphere containing radon above a certain level. Please use the following link to the HSE RADAN digital platform which has been designed to accept notifications on behalf of HSENI.

Before you start

Notification

You will need to notify HSENI if you work in an atmosphere containing radon above an annual concentration of 300 Bq m^-3. This is the most common reason for employers being required to notify HSENI.

You may also need to notify HSENI if you work with:

• artificial radionuclides or naturally occurring radionuclides, which are processed for their radioactive, fissile or fertile properties 
• naturally occurring radionuclides which are not processed for their radioactive, fissile or fertile properties
