Building materials used in Japan were collected from several companies and their
radionuclide concentrations were measured. Fifteen granite samples with high activity …

The contributions of radon and thoron from building materials to total radon (thoron) entry
rates in dwellings range from almost zero to several percent. It is necessary to measure …

Radon (222Rn) and thoron (220Rn) are radioactive gases emanating from geological
materials. Inhalation of these gases is closely related to an increase in the probability of lung …

Terrestrial radionuclides present in soil, bedrock and building materials are considered the
main source of indoor radon (222 Rn) and thoron (220 Rn). Due to its shorter half-life, 220 …

This study presents a corrected short-term model using the slope correction factor based on
existing short-term models for estimating radon exhalation rates of building materials using …

Background: We investigated the human risk due to radon and heavy metals (HM) in soil.
Methods: Samples were collected in 2017 from 10 representative geographical locations at …

The presence of high indoor radon concentrations, C x, is a major concern of the public
worldwide. Measurements of indoor radon in South Lebanon have been achieved using CR …

The objective of this study is to compute the primordial radionuclides activity in soil samples
and estimate the radon/thoron exhalation rates. A total of 25 locations were chosen for the …

Effective radium concentration ECRa, product of radium concentration and radon
emanation, is the source term for radon release into the pore space of rocks and the …

Among radiation exposure pathways to human beings, inhalation dose is the most
prominent one. Radon, thoron, and their progeny contribute more than 50 per cent to the …
