background: everyone is exposed to radon because it is present everywhere with varying concentrations. radon and its progeny are well established as lung carcinogenic. materials and methods: track etch technique using lr-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of etah district of uttar...

background: radon is an odourless, colourless and tasteless gas and it is the first cause of lung cancer among non- smokers. the assessment of the level of radium in building materials helps in understanding the radiological implications. it has been observed that everyone has some levels of exposure to them. therefore measurement of radium and radon in the soil samples are important from publi...

background: radon and thoron are invisible, odorless, heavy and radioactive gases which are ubiquitously present in dwellings and in the environment. in the present work, seasonal variation of indoor radon, thoron and their progeny concentrations has been studied in the dwellings of industrially polluted cities in district faridabad, haryana and district mathura in uttar pradesh. materials and ...

Background: Radon and thoron are invisible, odorless, heavy and radioactive gases which are ubiquitously present in dwellings and in the environment. In the present work, seasonal variation of indoor radon, thoron and their progeny concentrations has been studied in the dwellings of industrially polluted cities in District Faridabad, Haryana and District Mathura in Uttar Pradesh. Materials and ...

background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

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...

abstract  background: the essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. these two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...
