• Several types of electric pocket dosimeters have been developed recently. These dosimeters are distinguished by use of the silicone semiconductor as a radiation (γ-ray, X-ray) detector. Performance tests of a type of dosimeter named the PDM102 were carried out by using a 60CO point source (about 500kBq). The results showed that the minimum detectable dose equivalent for the dosimeter was 1-2μSv. Excluding cases of exposure from the underside or back of the dosimeter and exposure of less than 10μSv, differences between measured and calculated dose equivalents were less than 10%. Consequently the effect of the dose equivalent rate and dose equivalent (>10μSv) on the response of the detectors was determined to be less than 10%, and the directional dependence was also less than 10%. The dosimeter's response for back exposure was about 70-80% of that for front exposure. And for exposure from the underside of the dosimeter, the measured dose equivalents were equal to or less than approximately 50% of the calculated dose equivalents.
