Rn-222 has a short half-life (3.8 days) and decays into a series of solid particulate products, known as radon progeny or radon daughters, all of which have even shorter half-lives (∼30 min or less). Other isotopes of radon also occur naturally, but due to differences in half-life...
501 Words 3 Pages Open Document The indoor radon, thoron and their progeny concentrations is getting more attention day by day due to their health hazard effects on the population. Monitoring of indoor radon, thoron, and their progeny concentrations have become a global phenomenon due to their he...

Measurements were made in July 1994 to determine air exchange rate, aerosol characteristics, radon concentrations, and radon progeny activity size distributions in the Carlsbad Caverns. The measured radon concentrations were stable at a level of 1821 卤 55 Bq m3 (mean 卤SD). Using a SF6 trace ...
The complete product line provides all accessories for radon in air, water, soil, building materials, progeny, thoron and calibration equipment to perform air, water, soil and exhalation measurements. The collected data can be linked to the DataVIEW software, allowing data download and storage as...
Radon daughter products;Radon decay products;Radon progeny Definition Radon (Rn) is a chemically inert gas with atomic number 86 in the periodic table. The most stable isotope is radon-222 from the decay series of uranium-238. The half-life of radon-222 is 3.8 days. The short-lived daughte...
The influence of the measurement technique used to characterize the fraction of airborne radon progeny (short lived radon decay products of Rn: Po, Pb, and Bi) activity associated with ultrafine particles (in the size range 0.5-5 nm) was examined by comparing simultaneous measurements of the ...
