ICRP新的人呼吸道模型将在1993年正式出版。现对该模型的主要内容分若干次向大家作一介绍。这是第一篇介绍。1966年肺动力学工作组报告的出版和1979年在ICRP第30号出版物上刊登了呼吸系统剂量学模型之后,引起了人们在实验动物和人身上对吸入气溶胶的沉积、滞留、廓清和转移进行了大量研究。随后就出版了许多有关实验结果同根据ICRP肺模型得出的论断进行比较的报告。毫不奇怪,人们发现肺模型在许多场合是很需要的。批评最多的则是针对D,W,Y廓清分类系统。许多放射性化合物在动物实验或对人受到内照射后所进行的研究,发展它们的呼吸道廓清率和 ICRP new human respiratory model will be officially published in 1993. Now the main content of the model points to introduce you to several times. This is the first introduction. The publication of the report of the Working Group on Pulmonary Pneumodynamics in 1966 and the publication of a respiratory system dosimetry model in ICRP publication No. 30 in 1979 have caused the deposition, retention, clearance and decontamination of inhaled aerosols in laboratory animals and humans A lot of research has been done on the transfer. Subsequent reports were published comparing experimental results with those based on the ICRP lung model. Not surprisingly, it has been found that lung models are needed on many occasions. The most criticized is for D, W, Y clearance classification system. Many radioactive compounds have been studied in animal experiments or after exposure to human internal radiation to develop their respiratory clearance rates and
