Variation of radon progeny concentration over a continental location
Background: The variation of the radon progeny concentration in outdoor environment and meteorological parameters at fine resolution were studied for one year at a continental location, National Atmospheric Research Laboratory, Gadanki, India. Materials and Methods: The concentrations were measured using Alpha Progeny Meter by collecting air samples at a height of 1 m above the Earth&rsqu...
متن کاملContribution of radon and radon daughters to respiratory cancer.
This article reviews studies on the contribution of radon and radon daughters to respiratory cancer and proposes recommendations for further research, particularly a national radon survey. The steady-state outdoor radon concentration averages 200 pCi/m3, and indoor levels are about 4 times higher. The primary source of radon in homes is the underlying soil; entry depends on multiple variables a...

متن کاملCarcinogenic and Cocarcinogenic Effects of Radon and Radon Daughters in Rats.
It has been previously established that lung cancer could be induced in rats by exposure to radon and radon daughters. Although the oat-cell carcinomas that are common in humans were not found in rats, other histological types of lung carcinomas, especially squamous cell carcinomas and primitive lung adenocarcinomas, were similar to those observed in humans. A dose-effect relationship was estab...
متن کاملOutdoor radon concentration in China
The annual effective dose to Chinese population from natural radiation exposure is about 3.1 mSv/y, of which 1.56 mSv/y or 50% is due to the exposure from radon and its daughters [1]. The enhanced natural radiation level results mainly from indoor radon concentrations rising by 70%, compared to the previous data in 1990s [1, 2]. Based on the research, the increase in indoor radon concentrations...
