In the United States, radon is measured through primary and secondary testing, and a similar method is used in Canada. In the United Kingdom, only long-term radon measurements are taken with seasonal adjustments. In the Republic of Author: Cheolmin Lee, Dajeong Lee.

from radon exposure, as also recently recommended by WHO [7]. Although the dose to the lungs arising from radon exposure in homes is due mainly to radon decay products rather than radon gas itself, radon concentration is more related to dose than to radon decay product concentration, and radon concentration measurements are appropriate to.
