Radon, 222Rn, is the major contributor to natural radiation in human environment. The exposure of high radon is known as one of the causative factors of lung cancer. Though thoron, 220Rn, has been a matter of study in atmospheric science, but it was often neglected compared to radon. It was considered that the amount of thoron in the environment is less than that of radon. However, recent studies show that thoron and its progeny sometime contribute significantly to the radiation dose in residential buildings. A review of methodologies, measurement protocols and concepts used in various thoron measurement surveys performed in India is presented in this paper. The results of measurements of thoron and its progeny, carried out in the Himalayan region and in the high background radiation area of the south-eastern coast of Odisha, India are also presented. The results obtained using various thoron measurements techniques and the resulting doses to the general public are discussed in details.

在室内环境中进行measurements测量的意义

on 222 Rn是人类环境中自然辐射的主要贡献者。高ra暴露被认为是肺癌的病因之一。虽然托伦220Rn是大气科学方面的研究问题,但与ra相比,它经常被忽略。据认为,环境中of的数量少于ra的数量。但是,最近的研究表明,ron及其后代有时会显着影响住宅建筑中的辐射剂量。本文介绍了在印度进行的各种测量测量中使用的方法,测量协议和概念。还介绍了在印度的奥里萨邦东南海岸的喜马拉雅地区和高背景辐射区进行的ron及其子代的测量结果。详细讨论了使用各种thoron测量技术获得的结果以及对公众产生的剂量。
