Abstract

Abstract The major part of the radiation dose that humans receive from natural radioactive sources is due to inhalation of radon and its decay products. The study focuses on radon concentration (CRn) investigation in kindergartens and nurseries in the district of Montana. The influence of building characteristics on CRn was evaluated. The measurement of the CRn was performed using passive detectors. The survey was carried out between December 2019 and May 2020 with a total number of 602 detectors. The average value of CRn in the premises of the studied kindergartens and nurseries in this district is 125 Bq·m−3, and the geometric mean (GM) value is 88 Bq·m−3. The buildings that have built ventilation and sewerage systems have lower CRn. The effective doses of the children and workers were evaluated in order to assess the radon exposure.

保加利亚一个地区幼儿园的氡暴露情况

摘要人类从天然放射源获得的辐射剂量主要是由于吸入氡及其衰变产物。这项研究的重点是蒙大拿州幼儿园和托儿所的氡浓度（CRn）调查。评估了建筑特征对CRn的影响。使用无源探测器进行CRn的测量。该调查于2019年12月至2020年5月进行，共有602个探测器。该地区所研究幼儿园和托儿所的CRn平均值为125 Bq·m−3，几何平均值为88 Bq·m-3。建造了通风和污水处理系统的建筑物的CRn较低。对儿童和工人的有效剂量进行了评估，以评估氡暴露情况。
