Abstract
In order to give an accurate measurement for ambient dose monitoring, the residual dose should be reduced to an order of 0.1 mSv and Al203: C dosemeters are to be annealed by users just before service operation. An easy new annealingprocess for this purpose has been studied by using common fluorescent lamps with films that cut ultraviolet components. We made a series of annealing tests of Al203: C detectors by this method. The average residual dose by exposing to bare lamps was 0.13 mGy, while it decreased to one tenth; i. e. 0.01 mSv, by using the ultraviolet cut films. The test results show that use of common fluorescent lamps with ultraviolet cut films provides an easy and practical annealing method for measuring ambient doses by Al203: C detectors.
