In March 2006, the Health and Safety Executive made available the third edition of PM77 'Equipment used in connection with medical exposure' on the HSE website by following hte link below.
This document addresses the requirement for reporting of incidents where a radiation employer suspects or has been informed that a person was, while undergoing a medical exposure was, as a result of a malfunction or defect in radiation equipment, exposed to ionising radiation to an extent much greater than intended - the Ionising Radiations Regulations 1999, Regulation 32(6).
Currently, there is no similar specific guidance issued by DH regarding the reporting of incidents resulting in a person undergoing a medical exposure who was, otherwise than as a result of a malfunction or defect in radiation equipment, exposed to ionising radiation to an extent much greater than intended - the Ionising Radiation (Medical Exposure) Regulations 2000 Regulation 4(5). DH is currently reviewing this and guidance is expected to be issued in the near future. Until then, the advice given by DH in the general guidance document on IR(ME)R should be followed: - ie the term much greater than intended for IR(ME)R 2000 should be interpreted as in the HSE guidance PM77 second edition issued in 1998.
