The article presents approaches to the establishment of criteria (requirements) of radiation safety to the decontaminated areas of the territory, buildings and decommissioned facilities of use of atomic energy and other types of practical activities with sources of ionizing radiation. The main directions of further use of the decontaminated areas of the territory, buildings, and constructions, including 5 scenarios of restricted and unrestricted use, are determined; the criteria of radiation safety in the term of a dose constraint of a critical group of the population in 0.3 mSv/year living or working on decontaminated objects are established; the controlled parameters of the radiation situation and their levels, as well as the list of radionuclides subject to control are justified. The article presents the values of specific activity (Bq/kg) of residual radioactive contamination of soils and materials of buildings and structures, the radiation dose to the population in which will not exceed 0.3 mSv/year. Based on the presented data, draft sanitary rules and guidelines have been developed.

There are 143 men (group I) with idiopathic infertility in the form of asthenozoospermia of the II degree living in the territories of the Kiev region (Poles’ky, Chernobylsky, Ivan’kovsky, Borodyansky, Vyshgorodsky districts) were investigated in the Department of Sexual Pathology and Andrology of the SI «Institute of Urology of the National Academy of Medical Sciences of Ukraine» and exposed to ionizing radiation due to the Chernobyl accident in 1986. All individuals in the I group were born from parents who were in the accident at the Chernobyl nuclear power station in the area of radioactive contamination and permanently resided in areas with a high level of radioactivity. The control group was made up of persons born and living in the Ivano-Frankivsk region with a similar condition (group II, n=57). The mean age of the studied group I was 28,3±2,4 years, and persons of the II group were 30,1±2,8 years. Diagnosis of II was performed ambulatory in accordance with WHO and Ministry of Health of Ukraine standards. The study was to study and compare spermogram parameters in patients from both groups. It has been established that the reproductive problems of men with idiopathic infertility living in radiation-polluted areas of the Kiev region of Ukraine consist in a significant violation of the quality indicators of ejaculate (mobility by the pool A+B is less than 1,6 times, p<0,05) correlating with modifications of physicochemicals (the average time of liquefaction is 1,4 times greater, p<0,05) and biochemical (decrease of levels of fructose by 2,2 times, citrate – by 1,6 times, p<0,01–0,05) data characterizing the effect of ionizing radiation, as one one of the leading factors of male genital function violation. The study found that the level of general indicators of spermogramm is significantly worse in the regions of Ukraine who were exposed to radioactive contamination due to the Chernobyl accident, in contrast to the indicators of persons from conditionally pure regions.

Radiation Sources

Currently, there are critical ecosystems that accumulate radionuclides and determine the duration of radiation exposure on biota. The dose of external exposure caused by two factors – radioactive contamination of forest stands and the human behavior mode. In this work, authors represent the analysis of structure of ionizing radiation sources in forest stands at the territory with radioactive contamination. A method for estimating values of external radiation dose is based on calculation of protection against extended sources of ionizing radiation. A calculation data source is information on contamination density, wood species and forest type. We used taxation characteristics of pine stands to determine configuration and radiation sources composition. Calibration and verification of proposed model were carried out by dose rate in situ measurements by different methods. The results of comparison of the exposure dose rate in the meadow-forest areas confirmed the existence of the so-called “edge effect”. Experimental data is in a good agreement with the model calculations. A forecast of external exposure dose in pine forests for a remote period after the accident at ChNPP has been obtained. The method allows to improve radiation safety measures of forestry engineers, worked at forest sites.

Surface Bond

Modern surface analysis is based largely upon the use of ionizing radiation to probe the electronic and atomic structure of the surfaces physical and chemical makeup. In many of these studies the ionizing radiation used as the primary probe is found to induce changes in the structure and makeup of the surface, especially when electrons are employed. A number of techniques employ the phenomenon of radiation induced desorption as a means of probing the nature of the surface bond. These include Electron- and Photon-Stimulated Desorption (ESD and PSD) which measure desorbed ionic and neutral species as they leave the surface after the surface has been excited by some incident ionizing particle. There has recently been a great deal of activity in determining the relationship between the nature of chemical bonding and its susceptibility to radiation damage.
