The presence of many possible sources of radiation of dangerous intensity in todays nuclear physics laboratories has resulted in the use of various kinds of radiation meters for the protection of laboratory workers. Health Physics instruments of one class are placed in working regions to record the radiation intensity of integrated radiation some of these instruments are designed to alarm when intensity or integrated intensity reaches the danger point. Another class of Health Physics instruments is meant to be carried on the individual workers person. These instruments are more satisfactory than the fixed instruments since they read the integrated radiation near the workers. Despite their excellent accuracy and reliability, these instruments leave a lot to be desired since they do not provide an alarm and the person wearing them may find out some morning that he received a large overexposure the preceding day. This overexposure might have been avoided if the instrument had given an alarm when the safe daily dose had been received. This report describes this type of instrument and its construction.
