As an inert radioactive gas, 222 Rn could be easily transported to the atmosphere via
emanation, migration, or exhalation. Research measurements pointed out that 222 Rn …

Radon-222 is a naturally occurring radioactive gas that is part of the Uranium decay series.
Its Presence in the environment is associated mainly with trace amounts of uranium and its …

Abstract 222 Rn is a noble radioactive gas produced along the 238 U decay chain, which is
present in the majority of soils and rocks. As 222 Rn is the most relevant source of natural …

The present paper outlines characteristics of thoron and its progeny in the indoor
environment. Since the half-life of thoron (220Rn) is very short (55.6 s), its behavior is quite …

Radon-222 (222Rn) is a radioactive noble gas with a half-life of about 3.8 days, which is
naturally exhaled from soil into the atmosphere (eg Pal et al. 2015). It originates from the …

Results of a pilot study of 222Rn and 222Rn progeny outdoors and indoors in a valley of
enhanced radioactivity, affected by uranium mining and milling have been summarized …

Radon is a natural radioactive gas derived from geological materials. It has been estimated
that about half of the total effective dose received by human beings from all sources of …

Ever since studies on uranium miners established the presence of a positive risk coefficient
for the occurrence of lung cancer in miners exposed to elevated levels of 222 Rn and its …

Inhalation and ingestion are the two main routes upon which human beings are exposed to
radon and its decay products. Due to the electrostatics nature, radon can attach to solid …

Radon concerns the international scientific community from the early twentieth century,
initially as radium emanation and nearly the second half of the century as a significant …
