Public exposure from inhalation of radon and thoron around the tin mine and smelter areas in Bangka, Indonesia [PDF]
Scientific ReportsRadon (222Rn) and thoron (220Rn) were reported as the highest contributors to natural radiation received by humans. Furthermore, radon has been stated as the second-highest cause of lung cancer. The concentrations of 238U and 232Th (the parent nuclide of

Utilization of radiometric data for mapping primary and secondary sources of gamma radiation and radon/thoron release potentials in Ireland [PDF]
Frontiers in Public HealthBackgroundThis paper presents a novel approach to predict and map radon and thoron levels. We developed separate radon and thoron prediction maps for Ireland and introduced a system for producing high-resolution 3D radiation maps which may be used for ...

Nuclear Engineering and Technology, 2020 Building materials contribute significantly to the indoor radon and thoron levels. Therefore, parameters that influence the exhalation rates of radon and thoron from building material need to be analyzed closely.

Nukleonika, 2016 The health risk from thoron (Rn-220) is usually ignored owing to its short half-life (55.6 s), but the generated thoron decay products can cause a significant dose contribution.

INDOOR RADON, THORON AND THEIR PROGENY CONCENTRATIONS IN HIGH THORON RURAL SERBIA ENVIRONMENTS [PDF]
Radiation Protection Dosimetry, 2017 This article deals with the variation of radon (Rn), thoron (Tn) and their progeny concentrations expressed in terms of equilibrium equivalent concentrations (EERC and EETC), in 40 houses, in four villages of Sokobanja municipality, Southern Serbia. Two types of passive detectors were used: (1) discriminative radon-thoron detector for simultaneous Rn ...

220Rn (Thoron) Geohazard in Room Air of Earthen Dwellings in Vietnam
Geofluids, 2019 Thoron’s (220Rn) contribution to α-radiation exposure is usually considered negligible compared to that of 222Rn (radon). Despite its short half-life of 55.6 seconds, thoron can be exhaled from porous surface layers of building materials into indoor air ...

Indoor Radon and Thoron Measurement using CR-39 and LR-115 detectors in dwellings of Beni Mellal-Khenifra area (Morocco) [PDF]
E3S Web of Conferences, 2023 Radon and thoron are radioactive gases that are found naturally in the environment. They can seep into homes through cracks in the foundation, walls, and floors. Once inside, they can build up to levels that are harmful to human health.
