  2. Health effects of radon - Wikipedia

    en.wikipedia.org/wiki/Health_effects_of_radon

    Pb as observed in Japan as a function of time, due to variations in radon concentration. [4] Radon concentration in the atmosphere is usually measured in becquerels per cubic meter (Bq/m 3), which is an SI derived unit. As a frame of reference, typical domestic exposures are about 100 Bq/m 3 indoors and 10–20 Bq/m 3 outdoors.

    Radon concentration in open air varies between 1 and 100 Bq m −3. [6] Radon can be found in some spring waters and hot springs. [7] The towns of Misasa, Japan, and Bad Kreuznach, Germany boast radium-rich springs which emit radon, as does Radium Springs, New Mexico.

  4. Radon - Wikipedia

    en.wikipedia.org/wiki/Radon

    Radon concentration can differ widely from place to place. In the open air, it ranges from 1 to 100 Bq/m 3, even less (0.1 Bq/m 3) above the ocean. In caves or ventilated mines, or poorly ventilated houses, its concentration climbs to 20–2,000 Bq/m 3. [79] Radon concentration can be much higher in mining contexts.

    en.wikipedia.org/wiki/Background_radiation

    International radiation protection organizations estimate that a committed dose may be calculated by multiplying the equilibrium equivalent concentration (EEC) of radon by a factor of 8 to 9 ⁠ nSv·m 3 / Bq·h ⁠ and the EEC of thoron by a factor of 40 ⁠ nSv·m 3 / Bq·h ⁠. [2] Most of the atmospheric background is caused by radon and ...
