Dose estimation derived from the exposure to radon, thoron and their progeny in the indoor environment
The annual exposure to indoor radon, thoron and their progeny imparts a major contribution to inhalation doses received by the public. In this study, we report results of time integrated passive measurements of indoor radon, thoron and their progeny concentrations that were carried out in Garhwal Himalaya with the aim of investigating significant health risk to the dwellers in the region. The m...
متن کاملMeasurements of indoor radon, thoron and their progeny in Farrukhabad city of Uttar Pradesh, India
Background: More than 50% of the total dose received by human beings from all sources of radiation (both from natural and manmade) comes from radon and its progeny which is responsible for lung cancer in many cases. Materials and Methods: In the present study, the measurements have been carried out by using twin chamber dosimeter cups with LR-115 type-II detectors. The value of track ...
متن کاملAssessment of lung cancer risk due to indoor radon exposure in inhabitants of the state of Azad Kashmir Pakistan
Background: Several epidemiological studies conducted on underground miner’s show that exposure to elevated levels of radioactive radon gas is expected to increase the risk of lung cancer. Relative risk of lung cancer is almost linear with radon exposure. Elevated concentrations of radon are not only reported within mines but also for closed indoor environment of general public houses....
متن کاملInhalation Dose Due to Indoor Radon
The Rn and Rn enter the atmosphere mainly by crossing the air interface of either soil-air or building materials. The existence of relatively high indoor concentration maintains a large Rn, Rn concentration gradient between the materials and open air. The present paper deals with the experimental measurement of Rn, Rn concentrations and the associated inhalation dose rates due to them in the dw...
متن کاملComparative analysis of radon, thoron and thoron progeny concentration measurements
This study examined correlations between radon, thoron and thoron progeny concentrations based on surveys conducted in several different countries. For this purpose, passive detectors developed or modified by the National Institute of Radiological Sciences (NIRS) were used. Radon and thoron concentrations were measured using passive discriminative radon-thoron detectors. Thoron progeny measurem...
