Measurements of Indoor Radon Levels in India using Solid~State Nuclear Track Detectors: Need for Standardisation
Solid-state nuclear track detectors are being used to obtain the time integrated concentration levels of indoor radon/thoron and their daughters. This technique is preferred for taking such measurements in dwellings Such measurements are important as the radiation dose to human beings due to indoor radon constitutes more than 50 per cent of the total dose including that received from the natura...
متن کاملAssessement of Indoor Radon, Thoron and Their Progeny in Dwellings of Bareilly City of Northern India Using Track Etch Detectors
The levels of radon, thoron and their progeny in the dwellings of Northern India have been determined by using twin chamber dosimeter cups. The concentrations of radon and thoron were found to vary from 16.62–155.12 Bq/m and 4.16–24.93 Bq/m. Their progeny concentrations were found to vary from 1.80–16.77 mWL and 0.112–0.674 mWL. The values of life time fatality risk and annual effective dose we...
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 کاملSeasonal variation of radon, thoron and their progeny levels in dwellings of Haryana and Western Uttar Pradesh
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 ...
متن کاملSimultaneous measurements of indoor radon, radon-thoron progeny and high-resolution gamma spectrometry in Greek dwellings.
Simultaneous indoor radon, radon-thoron progeny and high-resolution in situ gamma spectrometry measurements, with portable high-purity Ge detector were performed in 26 dwellings of Thessaloniki, the second largest town of Greece, during March 2003-January 2005. The radon gas was measured with an AlphaGUARD ionisation chamber (in each of the 26 dwellings) every 10 min, for a time period between ...
