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: 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...

We exposed a stack of CR39 track detectors containing Ag foils to a 1.7 GeV/nucleon 56Fe'beam and investigated the anomalous mean free path effect. Neither the whole set of 7517 nor a subset of 2542 interacting fragments produced probably in the Ag target show an effect. By combining the data of this and an earlier experiment we can also exclude an effect for 3219 interacting fragments produced...

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 ...

The latest advances in the development of a fluorescent nuclear track detector (FNTD) for neutron and heavy charged particle dosimetry are described and compared with CR-39 plastic nuclear etched track detectors (PNTDs). The technique combines a new luminescent aluminium oxide single crystal detector (Al(2)O(3):C,Mg) with an imaging technique based on laser scanning and confocal fluorescence de...

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.
