Local probability of indoor radon concentration to exceed the threshold estimated from geogenic radon potential [PDF]

open access: yesNuclear Technology and Radiation Protection, 2017
Indoor radon has been recognized as an important air pollutant. Based on epidemiological evidence, it is estimated that indoor radon is the second cause of lung cancer after smoking.

Radon kinetics in a natural indoor radon chamber

open access: yesScience of The Total Environment, 2020
An unusual 180 m3 storage room in the basement of a two-story laboratory building is unventilated, and separated from occupiable rooms by double steel doors. The space completely borders on soil through the concrete floor and two of its concrete walls.
