A
Radon Detector
is used to find traces of Radon.
Radon
is a chemical element in the periodic table
that has the symbol Rn and atomic number 86.
What is Radon?
Radon is a gas
produced
by the radioactive decay
of the element radium.
(Source: USGS)
Radioactive decay is a natural, spontaneous process in which
an atom of one element decays or breaks down to form another
element by losing atomic particles (protons, neutrons, or
electrons). When solid radium decays to form radon gas, it
loses two protons and two neutrons.
These two protons and two neutrons are called an alpha
particle, which is a type of radiation. The elements that
produce radiation are called radioactive. Radon itself is
radioactive because it also decays, losing an alpha
particle and forming the element polonium. Radon levels in
outdoor air, indoor air, soil air, and ground water can be
very different.
Radon Detectors
and Radon Testing Kits are used to detect Radon in homes and
other buildings.
The decay of each radioactive
element occurs at a very specific rate. How fast an element
decays is measured in terms of the element "half-life", or the
amount of time for one half of a given amount of the element
to decay. Uranium has a half-life of 4.4 billion years, so a
4.4-billion-year-old rock has only half of the uranium with
which it started. The half-life of radon is only 3.8 days. If
a jar was filled with radon, in 3.8 days only half of the
radon would be left. But the newly made daughter products of
radon would also be in the jar, including polonium, bismuth,
and lead. Polunium is also radioactive - it is this element,
which is produced by radon in the air and in people's lungs,
that can hurt lung tissue and cause lung cancer.
Radon Mitigation and
Potential in the US
Geologic Radon Potential
The U.S. Geological Survey has
compiled a series of geologic radon potential assessments for the
United States in cooperation with the U.S. Environmental Protection
Agency (EPA). The geologic radon potential reports describe the
geology, soils, radioactivity, generalized housing construction
characteristics, and other relevant information, and include
discussions of the geologic factors controlling radon potential in
each state. The geologic radon potential areas are defined by geologic
boundaries, so that rock and soil units with similar radon generation
and transport characteristics are grouped and delineated in the
reports.
