近年来,有关放射性核素经动物和人的皮肤透入体内的报导显著地增多。同时积累的实验资料,对在实践上很重要的核裂变产物组分的放射性核素,还不能正确估算出在皮肤表层沾染时的组织吸收剂量。除了有~(90)Sr、~(137)Cs和~(131)I的报导外,还缺乏有关放射性核素在皮肤和内脏紧要器官内转移动态的资料。而
In recent years, there has been a significant increase in the penetration of radionuclides into the body through the skin of animals and humans. At the same time, experimental data accumulated, radionuclides of nuclear fission product components that are important in practice, can not correctly estimate the tissue absorbed dose when the skin surface is contaminated. In addition to the reports of ~ (90) Sr, ~ (137) Cs and ~ (131) I, there is a lack of information on the metastatic potential of radionuclides in vital organs of the skin and viscera. and
