| description | The study which had been conducted in the period from 1990 to 2000’s in the settlements ofGomelregion showed that the average internal exposure doses of population living in the settlements situated on territories with equal levels of contamination density were considerably different. The reasons for the difference have been revealed. It was shown that not only radiation contamination of territory but also a range of factors of non-radiation origin have influence on formation of internal exposure dose. The hypothesis has been approved that internal exposure dose of each individual and also of each family has its certain place, constant in time at a dose distribution curve. This appropriateness had been used as a methodological basis for reconstruction of subjects’ individual doses for any time period. Method for estimating the average annual effective exposure doses of inhabitants living in contaminated settlements of theBelarusRepublichad been developed. The results of the Whole Body Counter measurements had been used for direct assessment of internal exposure dose and as the basis for developing a model. Model for the dose estimation is based on the classification of settlements according to regional characteristics of soil, which cause 137Cs in taking with locally produced foodstuff. The model is also based on regression of daily 137Cs intake on the density contamination of the soil for each region. The effect of the indirect factors on the dose forming had been taken into account: the number of inhabitants and the area of forest around the settlement. According to the developed method, there had been created a Catalog of Average Annual Effective Doses of Residents of the Belarus Republic. |
