Radiation Measurement Instruments Radiation measurement instruments provide accurate radiation measurements in a variety of applications. From performing handheld gamma radiation measurements to measuring alpha and beta, radiation detectors make it easy to perform the measurements that are critical to any radiation safety program. These radiation monitoring instruments provide flexible options for most basic radiation detection scenarios. 1. What are radiation measuring instruments? Sources of ionizing radiation have important and indispensable uses in various industries to derive maximum benefit from their applications. To ensure radiation safety for radiation professionals, patients and the public; good radiation safety practices should be followed. The most important practice is to use radiation measuring instruments to measure the radiation in and around the source. 2. What are the types of radiation measuring instruments? The main types of radiation measuring instruments are: Surveyor, Dose Alarm Instrument, Radiation Monitoring System, Contamination Detector. 3. What are the important factors to be considered in the maintenance of radiation measuring instruments? Instruments should be kept in the best condition. Periodic calibration should be carried out as recommended by the authorities. If the instrument is repaired (or) the detector is replaced, the radiation measuring instrument must be recalibrated. 4. Where can these radiation measuring instruments be calibrated? Calibration cannot be done in any laboratory. The laboratory must be accredited by AERB (Atomic Energy Regulatory Board of India). AERB has further made it stringent that the laboratory must be accredited by an auditing body i.e. NABL. Such laboratories are required to calibrate the radiation measuring instruments at regular intervals.
