[en] Criteria for approval of laboratories which issue, process and assess personal dosemeters were drawn up by Technical Panel 7 (Radiological Measurements) of the British Calibration Service at the request of the Health and Safety Executive. The criteria, which were published in 1977, are set out in publications 0803, 0821, 0822 and 0823. Publication 0803 contains general criteria regardless of the type of dosemeter handled. It deals with organization and staff, accommodation and services, equipment and facilities, and the dosimetry service provided. Publications 0821, 0822 and 0823 contain supplementary criteria for services using particular types of film and thermoluminescent dosemeters. Whereas some of the criteria are considered to be obligatory others are regarded as recommendations giving some flexibility which allows laboratories to adopt procedures best suited to their own needs whilst maintaining standards required for approval.
