AlphaGUARD and AlphaPM used for Radon and radon progeny Risk assessment on an oil platform.
Molycorp Mountain Pass Minerals Mine, USA, started enhancing and modernizing the facilities. AlphaGUARD and AlphaPM have been used for a study to compare passive radon thoron detectors (track etch detectors) and real time detectors (AlphaGUARD). In case of passive monitoring once a high exposure event has been recorded that affects the average for that time frame irrespective of the lows for that period. Real time monitoring measures actual lows and highs of exposures and weighted averages are determined. Real time measurements and use of DataExpert software package allowed results for all areas to be displayed and reported prior to leaving platform.
