The Ionising Radiation Regulations

As required by The Ionising Radiation Regulations (Northern Ireland) 2017 employers must apply to the Health and Safety Executive Northern Ireland (HSENI) of certain work they do with ionising radiation and in advance of the work commencing. The following link will take you to the regulations:

The Ionising Radiation Regulations (Northern Ireland) 2017 (IRRNI17) came into force on 1 January 2018 and is based upon a risk-based approach to telling HSENI of your work with ionising radiation.

What you apply for depends on the size and likelihood of exposure, known as the ‘graded approach’.

Depending on the level of risk, before working with ionising radiation, as prescribed by the requirements of IRRNI17, you may need to:

  • notify HSENI - low risk activities
  • apply to HSENI for a registration - medium risk activities
  • apply to HSENI for consent - high risk activities

You’ll need to apply even if you’ve previously notified us that you work with ionising radiation. In addition, you might have to notify or hold registrations and consents at the same time. This depends on the work you do.

You’ll only need to notify or register ionising radiation work with HSENI once, no matter how many:

  • sites you have that carry out work which must be notified or registered
  • categories of work you do that must be notified or registered

The application can be submitted by an authorised employee. It can’t be submitted by a third party but they can advise you on your application.

We strongly advise you to consult with your radiation protection adviser (RPA) before you apply.
