[Complex sanitary and hygienic evaluation of water supply and community health in the area of the sulfite cellulose plants].

The study provides the results of the observation of the sanitary state of water area near discharge of sewage of a sulphite cellulose plant. Sanitary, chemical, bacteriological and toxicological characteristics of water and clastic deposits in the area of water abstraction systems used for economic and drinking purposes near a large inhabited locality are presented. Impact of a water factor on community morbidity and mortality rates has been analyzed.

[Age-related radiosensitivity of the crystalline lens in chronic experimental internal irradiation with 137Cs at low doses].

Internal whole-body irradiation of mice for 1 year with incorporated 137Cs at a dose of 0.5 eV was shown to make a significant cataractogenic effect on the lens. By annual rate this dose exceeded the existing maximum permissible dose only three times and was less than 10% of a cumulative dose for professionals having to do with ionizing radiation which they can accumulate at the maximum permissible dose level in annual irradiation for 50 years.

[Dose-effect relationship based on frequency of occurrence of radiation cataracts].

The paper is concerned with the results of experiments on random bred mice concerning dose-effect relationship estimated by radiation cataract developing 1 year after x-ray irradiation at doses of 0.05, 0.5, 4, 7 and 10 Gy.
