Exposure to indoor radioactive gases for long spells increases the risk of health-related issues. The primary mechanism contributing radon levels is transportation, subsequently exhalation from soil matrix/ building material matrix enclosed air dwellings. Long-term exposure elevated may lead possibility problems. use Radon Transportation Resistive (RTR) in construction reduce concentration. pur...

The reuse of by-products and residue streams is an important topic due to environmental and financial aspects. Manganese clay is a residue of manganese ore processing and is generated in huge amounts. This residue may contain some radionuclides with elevated concentrations. In this study, the radon emanation features and the massic exhalation rate of the heat-treated manganese clay were determi...

The radon isotopes (Rn-222 and Rn-220) and their progenies are responsible for more than 50% of natural radiation dose and the second leading factor in the case of the development of lung cancer after smoking [1]. Rn-222 (radon) and Rn-220 (thoron) are generated in crustal materials from their natural Ra-226 (U-238 decay series) and Ra-224 (Th-232 decay series) content, respectively. As a resul...

Various methods to determine 222Rn concentration in soil gas were tested at two sites with different soil types in a depth of 1 m. They include instantaneous (spot), continuous (real time) and timeaveraging procedures with advective ('active' procedures) or diffusive ('passive' procedures) gas transport from soil to detector: a) active grab-sampling of soil gas from different thin soil gas prob...

The transport of Rn through sealed, horizontal 2.54 cm diameter tubes filled with still water was observed to be significantly greater than that predicted solely from molecular diffusion. The rate of Rn transport was also found to be related to the concentration of Rn in the water. A constant source of radon producing an air concentration ranging from 1.1 to 176 Bq cm was connected to one end o...

Radon is a noble gas formed from the natural radioactive decay of uranium (U) and thorium (Th), natural components of the earth’s crust, which decay to radium (Ra) and then to radon (Rn). Decay chains include Ra and Rn for U; Ra and Rn for U; and Ra and Rn for Th. As radium decays, radon is formed and released into pores in the soil. Fissures and pores in the substrate allow the radon to migrat...

We show that energetic charged particles are produced during electrolysis of a D2O solution of Li2SO4 in a cell with a platinum anode and a palladium cathode. CR-39 plastic detectors, designed for recording alpha particles from radon decay, were immersed in the electrolyte during electrolysis. They recorded significantly larger numbers of energetic particle tracks than were recorded by control ...
