Abstract
A study of indoor radon dwelling of Bhadohi Uttar Pradesh, India. Radon is a colorless and odorless radioactive gas. Radon has been a natural component of the air we breathe. Radon is an invisible radioactive gas that occurs naturally in the indoor atmosphere. It comes from the naturally breakdown of uranium in soils and rocks. Lung cancer risk depends upon the concentration of radon, thoron and their decay product in air. Measurement of indoor radon concentration was carried out in the residential housdes, indoor and outdoor environment of district Bhadohi, Uttar Pradesh using solid state nuclear track detector (SSNTDs). Radon exists in soil gas, building materials, Indoor atmosphere etc. Solid state nuclear track detector using 25 dosimeters in indoor and 25 dosimeters in outdoor, the radon concentration were measured in total 50 dwellings of Bhadohi district in the eastern U.P.in the winter season and inhalation dose in (mSv/y). Significant variation of radon concentration was found in the different type of houses. A study of indoor/ outdoor radon dwelling of Bhadohi Uttar Pradesh, India. This paper presents the experimental calibration of LR-115 type II plastic track detectors for monitoring environmental radon. The indoor/ outdoor concentration however depends on various factors viz. ventilation condition, type of construction seasonal variation and geology of the area. Radon in dwellings originates from walls, floors and ceilings and also depends on the construction material. The conditions prevailing in India eastern region in the Utter Pradesh with respect to people’s life-styles, building construction type, topography and meteorological parameters are greatly different. Concentration of Radon measured in different houses, SSNTDs technique is used for present work in selected indoor/outdoor environments. Detector mounting for three months. Detector used in Bare on card mode and Dosimeter. Most of the houses in Bhadohi district are houses with typical construction their dense population, different geological and environment conditions which provide a wide scope of radon studies in this area. A result of measurements of radon concentration in Bhadohi (India) are presented.
