Abstract:
Objective To investigate the 90 Sr radioactivity in a certain environmental sample , and also to evaluate annual in-dividual effective dose in local residents .Methods Water, surface soil and biologic samples were collected in accordance with related national standards, then, after pretreatment, radiochemistry was used to detect and analyze 90Sr radioactivity in the samples, and annual effective dose in local residents was evaluated based on the detected data .Results The 90 Sr specific activity in water , surface soil and biologic samples in the region was relatively low , annual effective dose rate of 90 Sr in local residents was 1 μSv yearly, just 1‰of the annual limit specified by national standards .Conclusion The annual effective dose rate of 90 Sr in the local people could be termed as negligible .
