§ Mr. HancockTo ask the Secretary of State for Defence if installed personal IPM7 monitors are in use at RN Base Faslane; if personnel are monitored by IPM7 when they leave the yard; and if he will make a statement on the practice at other nuclear establishments. [69465]
§ Mr. SpellarOne IPM7 walk through monitor is installed in the Clyde Naval Base. When leaving classified areas all personnel are monitored for contamination by trained Health Physics staff using hand held instruments. They also have the option of using the IPM7 at this stage. In the very unlikely event that personnel are contaminated, they are taken to the Health Physics Group for decontamination, which includes compulsory monitoring by the IPM7.
At MOD-owned nuclear establishments, it is the practice to monitor the working environment and exposed personnel for possible contamination. Contamination monitors are used as part of the overall monitoring arrangements.
