[Remarks on the use of of several physical values in standards of radiation safety, health regulations and other documents]. / Zamechaniia k ispol'zovaniiu nekotorykh fizicheskikh velichin v normakh radiatsionnoi bezopasnosti, sanitarnykh pravilakh i drugikh dokumentakh.

The levels of radioactive substances in all standard documents and special literature is expressed by the rate of their disintegration, which is not correct. The main indicator of radioactive danger is surface pollution (for example, in Bq/km2). But pollution of surface can be uneven and in some places dangerous. Recommendations to correction of the matter are offered.

[Pneumonia morbidity in the personnel of x-ray offices]. / Zabolevaemost' pnevmoniiami u personala rentgenovskikh kabinetov.

Pneumonia incidence in roentgenologists was studied on the basis of temporary disability certificates for the period of 5 years. A significant increase in pneumonia incidence was noted, which gives the grounds to consider this disease as occupationally dependent for this category of people. A quantitative dependence of pneumonia incidence on the value of the accumulated collective dose during the period under study was established.

[Changes in the blood system after its extracorporeal irradiation]. / Izmeneniia v sisteme krovi posle ee ékstrakorporal'nogo oblucheniia.

One-stage extracorporeal beta-radiation of dog blood in a dose of 6-12 Gy is not followed by the development of radiation after-effects. Favourable changes in the peripheral blood content are marked. Erythrocyte carbohydrates undergo adaptation reconstruction with an increase in the percentage of nucleic acids. Over 7 to 30 days of observation the activity of nonspecific immunity factors such as lysozyme, lytic activity of beta-lysines, and phagocytosis also increases. At the same time the antimicrobial action of penicillin is potentiated. The data obtained can be used for correction of upset immune responsiveness.

[The levels of occupational irradiation of medical radiologists in the USSR from 1981 data on centralized individual dosimetric control]. / Urovni professional'nogo oblucheniia meditsinskikh radiologov USSR po dannym tsentralizovannogo individual'nogo dozimetricheskogo kontrolia za 1981 g.

By the 1981 centralized individual dosimetric control data using film dosimeters IFKU-1 the summary dose of medical radiologists in the Ukraine was 223 man-cSv X year-1. The mean annual doses in different occupational groups of medical radiologists varied from 0.07 to 0.60 cSv X year-1 and were in accord with the data available to the UN Scientific Committee on Atomic Radiation Effects concerning the levels of irradiation in similar professions in France, Canada and Austria in the period of 1974 to 1975. Persons in charge of the storage of radioactive substances are referred to high risk groups by the level of a mean annual dose (0.60 cSv X year-1). The distribution of irradiation annual doses of medical radiologists in the Ukraine was well approximated by Weibull function within the dose range of 0-1.1 cSv X year-1. This dose range accounts for 98.4% of all the cases. 1.6% of the persons received annual doses within the range of 1.1-3.5 per year-1, and their summary dose was 53.5 man-cSv X year-1. Basing on the data obtained a conclusion has been made that an increase in the frequency of stochastic effects in Ukrainian medical radiologists at the expense of occupational irradiation in 1981 is not to be expected.
