Gamtinės jonizuojančiosios spinduliuotės antropogeninių pokyčių tyrimas ir įvertinimas

Abstract

By dosimetric, radiometric research and by modelling the formation of exposure dose in the air layer close to the ground surface, by a set of experiments in the urbanised and non-urbanised environment it was identified that man while building houses, digging quarries, building roads etc., changes the intensity of natural ionising radiation at the same time changing the distribution of natural radionuclides. While identifying that: ·the ionising radiation changes due to anthropogenic activities, caused by natural radionuclides, were evaluated. ·the methodology of dosimetric research using global positioning system (GPS) was improved. ·a computer model was created with the help of which it is possible to evaluate the change of ionising radiation, moving away from or approaching different buildings.
