β计数法测定水环境中的^131I
Determination of ^131I in Water Environment by βCounting Method
摘要
Abstract
^131I is a very important nuclide applied in nuclear medicine ;also it is one of the most important fission nuclides released from nuclear leak accidents, so accurate determination of ^131I is very important for environment protection. First, we described β counting method in detail for ^131I in different water environment;Second,we determined ^131I in ocean water and radioactive waste water by this method. The experimental results showed that 1 ) The full chemical recovery rates of iodine varied from 85.39% to 94.47% and the average is 90.90% ;2) The volume activities of ^131Iin four parallel samples of ocean water were 0. 673 4- 0. 735 1 Bq/m3, while in radioactive waste water, the volume activities of ^131I were 16.80 -17.43 Bq/m3 ;the results of parallel sample determination suggested that reproducibility was good for this method.关键词
