强度平衡法测量<sup>59</sup>Fe放射性活度

强度平衡法测量⁵⁹Fe放射性活度

摘要: 1997,年日本ETL组织了59Fe溶液比活度测量的国际比对，本实验室采用HPGe 谱仪强度平衡法测量了59Fe的放射性比活度。测量结果为1.8367(11.0%)×103Bq/mg，与日本ETL的测量结果在-0.7%内一致。

Abstract: A sample of 59Fe solution for international comparison organized by Japan ETL in 1997 was measured specific radioactivity in our laboratory by using intensity balance method. The specific activity of sample 59Fe is 1.8367(1±1.0%)×10³Bq/mg, and the result is in agreement with the one measured by ETL（Electro Technical Laboratory）.
