High-resolution mapping along the coast and time-series measurements of the radon-222 (Rn) concentrations in the shallow zone in a semi-enclosed sea, Obama Bay, Japan, were undertaken in 2013. The temporal and spatial variations in the Rn concentrations were analyzed in parallel with meteorological conditions, physical–biogeochemical characteristics, and the submarine groundwater discharge (SGD...

Radon-222 diffusion in an anhydrous andesitic melt was investigated. The melts were glass discs formed artificially from melted volcanic materials. Solutions of the relevant diffusion equations were done by the explicit finite difference method. Results were compared to analytical solutions reported in the literature and good agreement was found. We have shown that the explicit finite differenc...

Extensive measurements of (222)Rn in the town of Xanthi in N Greece show that the part of the town overlying granite deposits and the outcrop of a uranium ore has exceptionally high indoor radon levels, with monthly means up to 1500 Bq m(-3). A large number of houses (40%) in this part of the town exhibit radon levels above 200 Bq m(-3) while 11% of the houses had radon levels above 400 Bq m(-3...

The present research was carried out to investigate the behavior of radon ( 222 Rn) concentrations over carbonate and evaporite sequences assess related health hazards. A total 50 points from three different stratigraphic units, namely, Bahadurkhel Salt, Jatta Gypsum, Kohat Formation Eocene age, were analyzed for in district Karak, Khyber Pakhtunkhwa, Pakistan. Measurements levels made by using...

Radon is a gas with symbol Rn and atomic number 86. It’s an active, colorless, odorless, tasteless gas formed from decaying of uranium. It is one of the densest gas, and also a health hazard due to its radioactivity. Uranium is the parent compound from which radon is formed. Uranium has been there since the earth was formed. Thus it will be present for millions of years in the same concentratio...

Abstract Backgrounds from long-lived radon decay products are often problematic for low-energy neutrino and rare-event experiments. These isotopes, specifically $${}^{210}\hbox {Pb}$$ 210 Pb , {Bi}$$ Bi {P...
