Abstract

In experiments of on rats a study was made of late effects of chronic action of tritium oxide (3HOH) during 6 months (37 X 10(4) Bq/g/day) and external gamma-radiation (137Cs) which were delivered in comparable daily and cumulative doses. It was shown that 3HOH produced a more pronounced blastomogenic effect. The RBE coefficient of tritium oxide approximated 1, with a reference to the average life shortening, and 4.2 and 2.5, with a reference to the incidence of malignant tumors and leukoses, respectively.

摘要

在对大鼠进行的实验中,研究了氧化氚(3HOH)在6个月内(37×10⁴贝克勒尔/克/天)的慢性作用以及外部γ辐射(¹³⁷Cs)的远期效应,二者的每日剂量和累积剂量相当。结果表明,3HOH产生了更明显的致瘤效应。氧化氚的相对生物效应系数,以平均寿命缩短为参照约为1,以恶性肿瘤和白血病的发病率为参照分别为4.2和2.5。
