In this paper, the evaluation of Rn-222 radioactivity content in drinking water samples from Calabria region, southern Italy, is reported as a case study. The Rn-222-specific activity analyzed groundwater for human use was evaluated by using PerkinElmer Tricarb 4910 TR setup and compared with parameter value (100 Bq L−1) reference Italian legislation, i.e., D.Lgs. 28/2016, derived European Dire...

Introduction: Exposure to indoor radon increases the risk of lung cancer. This study examined the level of indoor radon in dwellings of Khorramabad city, by using passive alpha-track detector (CR-39) during winter of 2016. Materials and Methods: In the present study, we detected the concentration of indoor radon in 56 dwellings. A passive sampling instrument (alpha-track detector with CR-39 pol...

Abstract Dynamic hydrologic exchange flows in river beds and banks are important for many ecosystem functions throughout corridors. Here we test whether the exchanges associated mixing between a flooding groundwater within river’s bank can be effectively traced by Radon‐222 ( 222 Rn), naturally occurring, inert, radiogenic, radioactive gas that analyzed monitored situ. The assessment was done s...

Abstract Long-lived radon daughters are a critical background source in experiments searching for low-energy rare events. Originating from ambient air, radioactive polonium, bismuth and lead isotopes plate-out on materials that later employed the experiment. In this paper, we examine cleaning procedures their capability to remove PTFE surfaces, material often used liquid xenon TPCs. We find lar...

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...
