We No Longer Offer Radon Testing Services
Radon Warning Statement
“The Minnesota Department of Health strongly recommends that ALL homebuyers have an indoor radon test performed prior to purchase or taking occupancy, and recommends having the radon levels mitigated if elevated radon concentrations are found. Elevated radon concentrations can easily be reduced by a qualified, certified, or licensed, if applicable, radon mitigator.
Every buyer of any interest in residential real property is notified that the property may present exposure to dangerous levels of indoor radon gas that may place the occupants at risk of developing radon induced lung cancer. Radon, a Class A human carcinogen, is the leading cause of lung cancer in nonsmokers and the second leading cause overall. The seller of any interest in residential real property is required to provide the buyer with any information on radon test
results of the dwelling.”
Disclosure Requirements
The Minnesota Radon Awareness Act does NOT require radon testing or mitigation. However, many relocation companies and lending institutions, as well as home buyers, require a radon test when purchasing a house.
Effective January 1, 2014, the Minnesota Radon Awareness Act requires additional disclosure and education be provided to potential home buyers during residential real estate transactions in Minnesota.Before signing a purchase agreement to sell or transfer residential real property, the seller shall disclose in writing to the buyer any knowledge the seller has of radon concentrations in the dwelling. The disclosure shall include:

Radon
NRPP Certification #107718RT Standard and Analytical
What you don’t see could kill you. Those are strong words but in today’s world of science and technology we can see things we never thought about in decades past. Our home, like many throughout the United States has high radon levels. Radon is a deadly gas that can be found in most parts of the world. It is thought to be responsible for an estimated 21,000 lung cancers deaths every year (US EPA). It is the second leading cause of lung cancer behind smoking. Testing for radon is easy and the results can give a home owner knowledge and peace of mind. If high levels of radon are found in your home you can take action to mitigate and ease your concerns. Efficiency Detectives can help you with your testing and help find a contractor licensed to do mitigation work for you.
Places where Radon can enter your home
A. Cracks in concrete slabs
B. Spaces behind brick veneer walls that rest on uncapped hollow-block foundations
C. Pores and cracks in concrete blocks
D. Floor-wall joints
E. Exposed soil, as in a sump or crawl space
F. Weeping (drain) tile, if drained to an open sump
G. Mortar joints
H. Loose fitting pipe penetrations
I. Open tops of block walls
J. Building materials: brick, concrete, rock
K. Well water (not commonly a major source in Minnesota homes)
Paul Schollmeier & Efficiency Detectives, LLC is nationally certified and registered with the Minnesota Department of Health to conduct radon measurements with continuous radon monitors. (Certification and training for radon measurement and mitigation is not required in Minnesota.)The requirements are outlined in this document from the National Radon Proficiency Program (NRPP).
Measurement Instruments
Efficiency Detectives uses two different methods of detecting radon in your home. The first is by using a continuous radon monitor (CRM). An instrument that is set up in the lowest livable location in your home. We use a Sun Nuclear Sentinel 1030 CRM that takes measurements every 60 minutes. We also use Corentium Pro CRM.Both are accepted devices and listed with NRPP. These monitors can be programed to sample radon periodically and can create reports that show how concentrations change over time and with changes in weather. Sample Report
A second method is one commonly used by home owners throughout the country but is often not procedurally followed. That method involves activated charcoal envelopes or disks that "adsorb" radon during the time they are placed. Placement is important as is following all the instructions for proper sampling and analysis. These envelopes also "desorb" radon while they are adsorbing.
