Measurements 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 کاملActivity of Ultrafine Fraction of Radon Progeny in Indoor Air
Inhalation of Rn progeny has been recognized as a health risk, primarily as a cause of human lung cancer. Rn progeny in the domestic environment contributes the greatest fraction of the natural radiation exposure to the public. The ultrafine activity of these progeny amounts up to about 10 percent of the total activity (attached and ultrafine), but is considered to yield about 50 percent of the...
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 ...
متن کاملIntegrating Radon Progeny Monitor
INTRODUCTION The Japan Nuclear Cycle Development Institute (JNC) carried out research and development projects related to uranium exploration in Japan from 1967 to 1987. Several mining facilities have been retained after the end of projects. Hence, the study on the behavior and the environmental impact of radon and its progeny from the mining facilities is being continued at the Ningyo-toge Env...
متن کاملExperimental determination of attachment function of radon progeny on aerosol particles
ABSTRACT Aerosol size information is very important for risk estimation of radon exposure. Size measurements of aerosol particles attaching radon progeny were made by using the Dekati's ELPI (Electrical Low Pressure Impactor), and its attachment function was determined. The impactor, which covers a wide size range from 0.03 to 10 μm in diameter, gives number size distribution in real time by an...
