Providers of
Precision Radon Decay Product and Radon Measurement Devices
Our Mission
The Progeny Group Limited is
dedicated to assisting consumers and air quality professionals to better
characterize health risks associated with indoor radon gas exposures by offering
measurement devices that measure BOTH radon decay products AND
radon gas.
Why not just measure
radon?
Measurement devices that measure only radon gas,
provide an indication of potential health risk. However, the primary
health risk associated with the presence of radon gas is due to the solid
particles that radon decays into. It is these radon decay products that
actually "stick" in the lungs that cause an increased potential for lung
cancer. Since the amount of radon decay products available for inhalation
can vary with house and atmospheric conditions, a radon gas measurement alone
does not fully characterize the actual health risk present in a building.
This is particularly true in buildings where high air circulation and the use of
air filters can have a large impact of reducing exposure to radon decay
products.
Why not just measure radon
decay products?
Since it is the decay products of radon that
present the primary health risk associated with the presence of radon, it is
logical that measurement of radon decay products would be preferable over radon
gas measurements. In fact, health risk studies are based upon either the
direct measurement or estimation of radon decay product levels.
Historically, radon decay product measurement devices have been expensive and
required complicated instrumentation, but not anymore! PGL in combination
with distinguished researchers and manufacturers have redeveloped technologies
to make these types of measurements very cost-effective. Nonetheless, PGL
believes that measuring radon decay products alone does not provide an
indication of the potential risk that could occur from a given radon gas level.
Why measure both
radon and radon decay products?
By measuring both radon and radon and radon decay
products, one is provided with a measure of the actual risk (from radon decay
products) and the potential risk (from radon gas). This provides a much
more thorough characterization than either measurement would by itself.
More importantly, the use of both measurements allows one to identify the
beneficial effects of air circulation, particulate air filters and clean indoor
air that serve to reduce exposure to radon decay products, that otherwise would
not be detected by a radon gas measurement alone. This can provide
significant economies, especially for buildings with high air circulation
(schools, commercial buildings, homes with forced air circulation, etc.) and
also provide alternative risk reduction techniques that can serve to improve
other indoor air quality concerns.
What if a Radon Decay
Product measurement is below EPA's action level, but the Radon measurement is
above EPA's action level?
"The question is often asked: Is radon decay product measurement an
acceptable procedure? The answer to this question is yes. EPA recognizes two
testing procedures. One is the direct measurement of radon decay products and
the second is the measurement of radon gas. Now if all factors are equal, the
direct measurement of radon decay products is the preferable approach and this
is because it provides the most accurate assessment of health risk."

Lammering, Radiation Program Manager, Region VIII, US EPA (ret.)

If the conditions that are causing the radon
decay products to be lower than the EPA's action level, such as air circulation,
air filters, clean air, etc., are conditions that are expected to exist during
normal occupied periods, then the radon decay product measurement takes
precedence over the radon gas measurements. However, if these conditions
are not maintained, then a very conservative approach would be to utilize the
radon gas measurements as an indication of the potential risk. The
advantage of the measurement devices provided by PGL, is that both
measurements are provided and one can make a much more informed decision on an
appropriate course of action.
