Measurements 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 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...
متن کاملRadon exhalation rates from stone and soil samples of Aravali hills in India
Background: The most popular building materials are soil bricks and different types of stones. Radon is released into ambient air from soil and stones due to ubiquitous uranium and radium in them, thus increasing the airborne radon concentration. The radioactivity in soils is related to radioactivity in the rocks from which the soil is formed. In the present investigation, the radon em...

متن کاملRadon and Thoron Progeny Measurements in Dwellings of Northern Greece
Radon progeny concentration is measured with a total alpha counting system in 185 dwellings in the town of Thessaloniki. The Equilibrium Equivalent radon Concentration (EEC Rn) follows a lognormal distribution with an arithmetic and geometric mean value of 28 Bq/m and 16 Bq/m respectively. Simultaneous in situ alpha and gamma spectroscopy measurements were performed in 60 schools of Thessalonik...
