Fifty granitic rock samples were collected from different plutons in the central part of the
Eastern Desert of Egypt and were analyzed for specific concentrations of 238U, 232Th and …

The radon adsorption coefficient of activated charcoal (K) has exponential relationship with
temperature theoretically, but few experiment results of K at temperature below 0℃ were …

The measurement of radon (222 Rn) activity flux using activated charcoal canisters was
examined to investigate the distribution of the adsorbed 222 Rn in the charcoal bed and the …

Charcoal canisters are widely used devices for measuring radon concentration in the
atmosphere, but they are sensitive to humidity. A newly designed super absorbent polymer …

Due to their high efficiency and speed of use, alpha scintillation cell is being increasingly
utilized for detection of radon (222Rn) in soil gas. The calibration factor of the 110 A active …

Open-faced charcoal canisters have been used for radon measurements for over 40 years.
This method is sensitive to temperature, changing radon concentrations, humidity and other …

Offshore floating nuclear power plant (OFNPP) is a significant solution for marine electricity
shortage. In this study, the optimized activated carbon for decay technology was studied in …

Underground low-background laboratories have a very large demand for radon reduction in
their working environments. Therefore, in this paper, we have constructed a system for low …

Radon adsorption by activated charcoal collectors such as PicoRad radon detectors is
known to be largely affected by temperature and relative humidity. Quantitative models are …

In the present study, the heat activation and vacuum activation have been used to re-
increase the adsorbed amount of Xe and Kr on activated charcoal for radioactive off-gas …
