Standard of limit on dose of radiation on - site detection for import and export granite 进出口花岗石现场放射性剂量检测控制标准
When the distribution of important fission products is calculated , emphasis is placed on the noble gas radionuclides and upon radioisotope of iodine because of their great contribution to accident dose 在对重要裂变产物分布的仿真计算中,重点放在了惰性气体核素和碘的放射性同位素上,因为它们是事故中放射性剂量的重要来源。
