BETA-GAMMA RADIATION SURVEY METERS & DIGITAL CONTAMINATION MONITORS
These meters are normally used for low level gamma dose rate measurements in Medical Cyclotron, PET-CT Centers & similar other facilities. Further these meters are used for swipe testing and also to check for Beta contamination of hands, foot, clothing, gloves and work areas. These meters are popular with Nuclear Medicine practitioners. In radiotherapy departments, these meters are widely used for swipe testing of – Cobalt therapy machine jaws, – Brachytherapy Source transfer tubes and LDR sources, also for inspection of other sources & source housings. For swipe testing, it is recommended that these meters are used in CPS or CPM modes.
Further, CPS / CPM modes are selected when these meters are used for Beta contamination measurements and the user has to open shutter or cover of the detector probe. For measurement of low level gamma dose rates, cover / shutter is to be kept in closed condition.
