摘要
Abstract
The specific activity of 60Co radioactive solution and Mco+99Tc mixing solution was absolutely measured by coincidence method. The specific activity of "Tc solution was calculated by efficiency tracing method with 60Co as tracer isotope. Final result is that the specific activity of 99Tc solution is (70. 8±1. 8) Bq · mg-1 (k = 2), which can meet the need of measurement task.关键词
