本文介绍了用 CaSO_4∶Dy-Teflon 薄膜剂量计测景泰兰产品表面剂量率的方法和结果。7类42种饰品以及各种瓶、盘、洗子等20件景泰兰工艺品的表面剂量率都在0.015mrad/h 以下,实际上大部分在天然本底的涨落范围之内。为了比较,还同时测量了台湾省产的几件饰品和日本产的三个瓶,其中台湾省产的链饰的表面剂量率较高,平均达到0.78mrad/h。 This article describes the methods and results of measuring the surface dose rate of Kelantan products using a CaSO 4: Dy-Teflon thin film dosimeter. Twenty-four categories of 42 categories of jewelery, as well as bottles, dishes, and washes, all have a surface dose rate of 0.015 mrad / h or less for most of the 20 natural shine ranges. For comparison, several pieces of jewelry produced in Taiwan and three bottles made in Japan were also measured. Among them, the surface dose rate of the chain ornaments produced in Taiwan is relatively high, averaging 0.78 mrad / h.
