On 1 January 2018 Ionising Radiations Regulations 2017 (IRR17) replaced IRR99.

This Approved Code of Practice and guidance now applies. It gives advice and direction on how to meet the requirements in the regulations.

The Ionising Radiations Regulations 2017 set out your minimum legal duties and the ACOP text and guidance within this publication give practical advice on how to comply with those Regulations. The format of this publication is designed to clearly distinguish between the Regulations, the ACOP and the guidance - the ACOP text is set out in bold and the accompanying guidance in normal type, the text of the Regulations is in italics. Coloured borders also indicate each section clearly.

It can also be used by self-employed people who work with ionising radiation and have certain duties under these Regulations both as an employer and as an employee.
