TIP: It is important that radon tests are done during “closed-house
conditions” of the home, meaning windows on all levels and doors to outside are
closed, except for going into and out of the house. In the Summer ‘whole-house AC
units’ can be operating on Auto, but ‘window AC units’ should not be used
during the testing.

November 12, 2016. Today a local Home Inspector
reported to us they have found two Active Soil Depressuirization Radon
Mitigation Systems in the area that did not penetrate the concrete
slab. These systems cannot work properly. We have found some over the
years as well. This could have been detected immediately after the RMS
installation if proper radon testing with closed house conditions
following applicable EPA or AARST-ANSI standards had been done. When in
a real estate
transaction we recommend buyers always conduct their own
test when they start living in the house.

From Tomorrow our access to Estes Park is going to be limited because
the Thompson Canyon is closed for travel for many months until

September 18-22, 2016. Dr. Leo Moorman visited
the International Radon Symposium in San Diego,
CA., organized by AARST

gave a course for advanced mitigators on Sunday, allowing the students
to earn 8 hours NRPP-CE for re-certification. He also delivered two
presentations later in the week during the Symposium. The two
presentations will be published as contributions in
the peer reviewed proceedings of the Symposium.
RHMM deployed short term radon tests at an educational institution in
Estes Park following the

Radon Home Measurement
and Mitigation (RHMM) performs radon testing and radon mitigation of
single and multi-family
homes as well as radon testing and mitigation in commercial or business
locations, and delivers radon education to
interested groups and the public. RHMM also helps with radon
emerging during real estate transactions, helping real estate brokers,
buyers and sellers to understand and deal with what may be a serious
environmental health issue in a home. Our goal is to identify those
places that represent a high radon exposure to the general public in
residential, commercial and business environment and, after
verification of an increased health risk, to fix the problem.
RHMM works with home owners, contractors and builders by pre-screening
building site before construction for its ability to show a radon risk
concern after completion. If this radon risk analysis shows a predicted
high concentration of radon, RHMM can install an effective
pre-mitigation system in new home construction. RHMM, located in Fort
Collins, can solve radon problems anywhere in Northern Colorado or

Colorado Department of Public Health and Environment (CDPHE) has given
us the information that currently 22 municipalities in Colorado have a
Radon Code. This has been steadily growing since Aspen in 2003 and Fort
Collins in 2005 started this trend.
2014 New data (CDPHE) have revealed that twelve
Colorado Counties previously considered to be at moderate risk for
exposure have been upgraded to the high-risk category. This
means all 64 Colorado
counties are now categorized
as Zone I, which is the category with highest average radon
following the EPA classification. When a house is at or above
pCi/L, the USEPA recommends mitigation.
Spring is here: this is a good time to do a radon test.

A wonderful TED talk about the discovery of radon and the two famous
scientists who competed over a century ago for the honor of its
discovery. Rutherford vs. Ramsay. How did they discover it? By
looking at the "ultraviolet (UV) light spectrum" and
identifying it as different
from other known ultraviolet light spectra, such as that from helium.
In this Ted talk the original ultraviolet light spectrum recorded by
Rutherford is shown identifying the UV light spectrum of the then
entirely new element, called Radium Emanation (Rutherford) or
Niton (by Ramsay), which later became "Radon".

A so called "diffusion cloud chamber" can show the alpha
tracks in real life after radioactive decay when the ionizing
alpha particles released by the
atomic nucleus create milions of tiny (mist) droplets along their
pathway through a supersaturated vapor.
The alpha particles start with a
daunting velocity of 20%
of the speed of light. This instrument is called a "cloud
since the principle on which it works is reminiscent of the process how
clouds are formed in the sky.
