NEW THERMOLUMINESCENT DOSIMETER
A dosimeter design is described in which a thermoluminescent phosphor is mounted on an electrically heatable support in an evacuated or gas-filled envelope. With CaF/sub 2/: Mn as the phosphor, the device detects gamma doses in the milliroentgen range and has linear response to 2 x 10/sup 5/ r. Dose readings can be made in less than a minute with simple instrumentation requiring no darkroom facilities. The dosimeter may be reused many times. The response is independent of dose rate for at least 10 mr/min to 7000 r/min. With suitable tin shields the response is independent of energy at 40 kev to 1.25 Mev. The advantages of this device for personnel monitoring in health physics operations are pointed out. (auth)
