The research work was aimed to determine the fatal cancer risk due to the radiation exposure on population of Bangladesh. The total risk is somewhat higher. However, the average total fatal probability coefficient was found to be 101 cases per million people, the range of which was from 78 to 144 per million people. The lowest risk was found for the people of Srimangal (Maulavibazar) and Sandweep, while the risk was highest for the people of Nachole (Chapai Nawabgonj) and Badalgachhi (Naogaon), the two locations are in the Borendra region. The risk factors were found to be around average level for the people of Dhaka, Chittagong and Rajshahi. Since a very significant portion of people of Bangladesh live in these areas, the calculated average risk factor become more meaningful. Moreover, as both the average effective dose equivalents and the population density in Bangladesh are higher than those of the countries compared, the people of Bangladesh are in more risk than those countries.
该研究工作旨在确定孟加拉国人口因辐射暴露而面临的致命癌症风险。总体风险略高。然而，平均总致命概率系数为每百万人101例，范围为每百万人78至144例。发现斯里曼加尔（毛拉维巴扎尔）和桑德韦普的居民风险最低，而纳乔莱（查派瑙瓦贡杰）和巴德尔加奇（瑙冈）的居民风险最高，这两个地点位于博伦德拉地区。达卡、吉大港和拉杰沙希的居民风险因素处于平均水平左右。由于孟加拉国很大一部分人口居住在这些地区，计算出的平均风险因素变得更有意义。此外，由于孟加拉国的平均有效剂量当量和人口密度均高于所比较的国家，孟加拉国人民比那些国家面临更大的风险。
