A new scientific study in Environmental Health Perspectives estimated the
global lung cancer mortality attributable to Residential Radon over the year
2012. This value (PAR) for the sum of all 66 countries studied was estimated to
be 226,057 individuals. Authors: J Gaskin, D. Coyle, J. Whyte and D. Krewski, Environmental Health Perspect, https://doi.org/10.1289/EHP2503

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 test.

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 additional
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 May
2017. Access via Highway 36 from Fort Collins will add
substantial miles and time.
September 18-22, 2016. Dr. Leo Moorman visited
the International Radon Symposium in San Diego, CA., organized by AARST
and jointly held with the CRCPD. He
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.
August 31-September 2:
RHMM deployed short term radon tests at an educational institution in Estes Park following the
"Schools and Large Buildings" guidance. Proper testing
required 23 radon test devices for this facility.
August 24-26, 2016 with
temperatures cooler than most of the Summer, RHMM is measuring radon
levels in 80 apartments locally, and finishing up with 14 final tests
at the Air Force.
July 24, 2016 RHMM is starting this week to mitigate 10 Large Buildings, each with 8 apartments located in Fort Collins.
July 20, 2016 We
finished a large survey with 470 radon tests at the F.E. Warren Air
Force base in Cheyenne, WY. All newly built housing for personnel must
be tested within the first 5 years of occupancy. The report
shows in detail that we passed all the required Quality Assurance and
Controls that are needed in case of such a large survey. That
means we proved that the radon tests were sufficiently accurate to
make mitigation decisions.
July 9, 2016 The
proof of new membership of AARST is in. This is the official
National organization working hard to promote (1) education
proper insurances for its members, (2) administer the development
of National radon standards and (3) administer the AARST-NRPP
certification program for Testing and Mitigation and (4) organize a
yearly National Symposium for its members
which in September 2016 will be held in San Diego. AARST also
members pledge (5) they abide by proper industry and busines
ethics as they deal with the public and promote the risk reduction
of such a sensitive issue as lung cancer causing radon
gas. At RHMM we are proud our president has been a member of AARST
the last 16 years and has actively helped develop and
improve the organization via a past two term National Board membership
standard writing committees and the review committee for the Symposium
publications. This is a very valid organization to the public
by that it improves the
trust in radon testing and mitigation when performed by certified
especially in otherwise environmentally unregulated states such as in
Colorado and Wyoming and others.

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

Every year in
the USA 21,000 people acquire radon related lung
cancer according to the EPA, which means an average
of 58 people per day. Most of
these lung cancers are preventable if all the
houses the affected people had
lived in during their lifetime had properly working radon mitigation
systems installed. In addition the EPA advice is to test homes
radon systems regularly, such as once every two years, because the
radon entry pathway into a house can change over time.

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.
Although you need to know that a
term (>=2 days) test is conducted with outside doors and windows
closed, except you can live there and may open doors to go in and out

Awareness Week is here according to The Surgeon General. Health
agencies throughout the United States have joined forces to promote
awareness of the leading cause of lung cancer for non-smokers.
The American Lung Association Centers for disease Control, and National
Cancer Institute all agree the radon is a national
health problem and encourage radon testing during
the October awareness drive.

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.
