[Comparative evaluation of the carcinogenic effects of chronic exposure to tritium oxide and external gamma-radiation]. / Sravnitel'naia otsenka blastomogennogo éffekta khronicheskogo deistviia okisi tritiia i vneshnego gamma-oblucheniia.

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.
