Abstract

Studies on ambient gamma radiation in indoor and outdoor environment and their effect on human health have created interest among the researchers across the world. The present study represents the results of indoor and outdoor ambient gamma dose rates around the Kaveri river basin from Talakaveri (Madikeri district) to Mekedatu (Ramanagara district) by using portable Environmental Radiation Dosemeter. The annual effective dose in the present study area varies between 0.14 mSv.y-1 and 0.58 mSv.y-1 with an average value of 0.30 mSv.y-1 for indoor radiation. The outdoor annual effective dose ranged between 0.01 mSv.y-1 and 0.14 mSv.y-1 with an average value of 0.06 mSv.y-1. The total annual effective dose varies from 0.17 to 0.72 mSv.y-1 with an average value of 0.36 mSv.y-1. The calculated values of indoor and outdoor annual effective dose in the study area (are found to be lower than the world average values (1 mSv.y-1 and 0.48 mSv.y-1).

摘要

对室内和室外环境中的环境伽马辐射及其对人类健康的影响的研究引起了世界各地研究人员的兴趣。本研究使用便携式环境辐射剂量计，代表了从 Talakaveri（Madikeri 区）到 Mekedatu（Ramanagara 区）的卡弗里河流域周围室内和室外环境伽马剂量率的结果。本研究区域内的室内辐射年有效剂量在 0.14 mSv.y-1 至 0.58 mSv.y-1 之间变化，平均值为 0.30 mSv.y-1。室外年有效剂量在 0.01 mSv.y-1 至 0.14 mSv.y-1 之间变化，平均值为 0.06 mSv.y-1。总年有效剂量在 0.17 至 0.72 mSv.y-1 之间变化，平均值为 0.36 mSv.y-1。研究区域内室内和室外年有效剂量的计算值（低于世界平均值（1 mSv.y-1 和 0.48 mSv.y-1）。
