Sorption of Cs and Co on Titanium Oxide Films in Light Water Reactor Primary Circuit Environment.

This paper discusses the processes of the long-lived Cs and Co immobilization on titanium surfaces in simulated light water reactor primary circuit environments. This study is prompted by numerous problems in both the maintenance of equipment during reactor operation and the dismantling of the reactor after the completion of the operation, which is associated with contamination of working surfaces with long-lived radionuclides. The composition of the oxide films formed on the surface of commercial titanium alloy ПT-3B has been studied with specimens prepared in autoclave test conditions and surface samples from the pipeline sections to which the primary coolant was applied.

Review of Russian research with radioactive particles: Foliar uptake.

Studies performed in the former Soviet Union were reviewed to provide interception and weathering values for radioactive particles. None of these studies were available in the English language literature before or were considered in the international reviews. The estimated mass interception fractions ranged 0.

[Quantitative dependence of sheep death on dose and dose rate of external gamma-radiation].

The results of experimental studies of sheep death at different dose rates of gamma-radiation have been analyzed. Parameters of a mathematical dependence of animal death on the exposure dose and dose rate have been identified. The evaluation of adequacy of the derived equation has demonstrated that the established relationship correctly describes the experimental data in studied dose rate range.
