210Po activities in glass objects
In the present work, we used the (CR–LR) difference technique for retrospective radon progeny measurements in 17 dwellings based on implanted 210Po activities in glass objects. A total of 48 glass objects were examined, but only 19 objects gave results which were sufficiently reliable due to the sensitivity of the method. From these 19 data, an increase in the surface 210Po activities in the gl...
متن کاملCorrelation of 210Po implanted in glass with radon gas exposure: sensitivity analysis of critical parameters using a Monte-Carlo approach.
In recent years, 210Po implanted in glass artefacts has been used as an indicator of the mean radon gas concentration in dwellings in the past. Glass artefacts have been selected in many dwellings and the alpha-recoil implanted 210Po concentration has been measured using various techniques. Some of these retrospective techniques use a model to estimate the retrospective radon gas on the basis o...
متن کاملMeasurement of Contemporary and Retrospective Radon Concentration in Ramsar Dwellings Using Polycarbonate Detector
The origins of radon gas are the amount of uranium decay in the soil that is released into space and through the interior gaps of buildings. Radon can enter the respiratory system and cause radiation hazards. Recently research has identified Radon as the second leading cause of lung cancer after cigarette smoking. The indoor concentration of Radon progeny is mentioned as an important issue reg...
متن کاملAlpha particle emission from reference glass surfaces implanted with 210Po.
Implanted long-lived radon decay products in glass surfaces have been used as a measure of past radon exposure in homes. Special track-etch devices (so-called 'retro-detectors') attached to the glass surface, have the ability to specifically measure the implanted activity of 210Po in situ. Calibrating these devices for 210Po is fairly straightforward, but the retro-detectors are also sensitive ...
متن کاملIntercomparison of retrospective radon detectors.
We performed both a laboratory and a field intercomparison of two novel glass-based retrospective radon detectors previously used in major radon case-control studies performed in Missouri and Iowa. The new detectors estimate retrospective residential radon exposure from the accumulation of a long-lived radon decay product, (210)Pb, in glass. The detectors use track registration material in dire...
