ALL veterinary practices should be aware that the Ionising Radiation Regulations 2017 come into force on 1 January 2018 and replace IRR99.

There is an immediate requirement for all radiation employers (from now referred to as employers) to re-notify the Health and Safety Executive (HSE). Some sites may have to additionally register and obtain consent to operate.

Employers with multiple sites only have to register once. Online application will be available, but appears not yet to be in place. Draft guidance notes can be downloaded. It is not anticipated that the new regulations will have a massive impact on the profession but it is worth noting the following changes (this may not be exhaustive): requirement to put procedures in place to estimate doses to members of the public, lowering of dose limit to the eye, removing of the subsidiary dose limit for the abdomen of women of reproductive capacity and recording and analysis of significant events such as radiation accidents.

Note that a radiation accident in itself does not have to be reported to the HSE.
