Radiation monitoring

Personal monitoring devices

Under section 50 of the Protection from Harmful Radiation Regulation 2025 an employer must ensure that employees who are occupationally exposed to the use of ionising radiation for any one of the purposes listed under this clause are issued with appropriate approved personal monitoring devices (PMDs) for detecting and measuring cumulative exposure to ionising radiation.

The clause also specifies that an occupationally exposed person has an obligation to wear the device while involved in the use of ionising radiation.

Section 51 of the Regulation requires that an employer must ensure that a record of exposure is kept for each occupationally exposed person to whom a PMD is issued.
