The Indian Environmental Radiation Monitoring Network continuously monitors, throughout India, the absorbed dose rate in air due to outdoor natural gamma radiation, by using Geiger-Mueller detector-based standalone environmental radiation monitors. The network consists of 546 monitors spread across 91 monitoring locations distributed all over the country. In this paper, the countrywide long-term monitoring results are summarised. The measured mean dose rate of the monitoring locations followed a log-normal distribution and ranged from 50 to 535 nGy.h-1 with a median value of 91 nGy.h-1. Due to outdoor natural gamma radiation, the average annual effective dose was estimated to be 0.11 mSv.y-1.
印度环境辐射监测网络通过使用盖革-弥勒探测器为基础的独立环境辐射监测器，在印度各地持续监测室外自然伽马辐射导致的空气吸收剂量率。该网络由分布在全国的 91 个监测点的 546 个监测器组成。本文总结了全国范围内的长期监测结果。监测点的测量平均剂量率呈对数正态分布，范围为 50 至 535 nGy.h-1，中位数为 91 nGy.h-1。由于室外自然伽马辐射，估算的平均年有效剂量为 0.11 mSv.y-1。
