Radon, an element of natural radiation, is considered one the leading causes lung cancer worldwide. In Bangladesh, radon has been clarified as a foremost source radiation exposure. Potential natural-radiation-induced elevated risks were estimated in Bangladesh previously for population. this survey, very preliminary study country, comparative indoor (222Rn, Rn) and thoron (220Rn, Tn) concentrat...

The Bat Xat district in the Lao Cai province of Vietnam has enormous potential for resources copper and rare earth minerals. In fact, exploration exploitation activities these minerals have brought about positive economic benefits to this area recent years. However, activity also brings negative impacts on environment surrounding population. mineral deposits contain a significant content radioa...

Study of radon, thoron and their progeny are important from radiological point view. This work is towards prediction, measurement, decay behavior, estimation associated factors effective dose for different room conditions (open closed). The levels measured experimentally using active monitors, dosimeters deposition-based sensors. Radon found uniformly distributed the open condition while shows ...

Radon and thoron are significant contributors for radiological risk in indoors originating from decay chain of uranium thorium, which prevalent the environment. These concentrations depends on presence thorium concentration, lifestyle habitants. The village “Peddamula” is located neighbourhood area proposed mining exploration uranium. estimated concentration radon found range 14- 448 Bq.m-3 wit...
