本文係評估桃園地區天然幅射中伽馬射線的體外暴露所導致的遺傳影響等效劑量。 桃園地區天然背景幅射暴露率平均值是11μR-hr^(-1);年集體等效劑量是1.01×10^5man-rem,遺傳影響劑量是86.8mrem-person^(-1)-yr^(-1)。
The genetically significant dose equivalent from environmental gamma-ray exposure of natural radiation in Tao-Yuan county of Taiwan has been estimated. The distribution of the exposure rates and the population-weighted annual collective dose equivalents in Tao-Yuan county was obtained. The mean exposure rate of natural radiation background was calculated to be 11 μR-hr^(-1). Annual collective dose equivalent in Tao-Yuan county was calculated to be 1.01×10^5 man-rem. The genetically significant dose equivalent per person was 86.8 mrem-yr^(-1).
