Dose assessment for radon and thoron concentrations in iraqi thermostone bricks [PDF]
E3S Web of Conferences, 2023 This research aims to measure radon (222Rn) and thoron (220Rn) concentrations for selected thermostone bricks samples produced in Iraq. 222Rn and 220Rn concentrations were measured using the active method (RAD7 detector).

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 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.
