Checklist for Consumers

(Source: NEHA-NRPP.org)

The EPA publishes a number of informative documents about radon for consumers. Many of the radon related booklets are available through the EPA’s website (www.epa.gov/radon/pubs) or through state radon offices.The EPA’s Consumer’s Guide to Radon Reduction provides guidelines for radon mitigation.The Home Buyer’s and Seller’s Guide to Radon http://www.epa.gov/radon/pubs/hmbyguid.html includes the following guidelines regarding radon measurements:Radon Testing Checklist
For reliable test results, follow this Radon Testing Checklist carefully. Testing for radon is not complicated. Improper testing may yield inaccurate results and require another test. Disturbing or interfering with the test device, or with closed-house conditions, may invalidate the test results and is illegal in some states. If the seller or qualified tester cannot confirm that all items have been completed, take another test.

Before Conducting a Radon Test:
  • Notify the occupants of the importance of proper testing conditions. Give the occupants written instructions or a copy of this Guide and explain the directions carefully.
  • When doing a short-term test ranging from 2-4 days, it is important to maintain closed-house conditions for at least 12 hours before the beginning of the test and during the entire test period.
  • When doing a short-term test ranging from 4-7 days, EPA recommends that closed-house conditions be maintained.
  • If you conduct the test yourself, use a qualified radon measurement device and follow the laboratory's instructions. Your state or county extension office may be able to provide you with a list of do-it-yourself test devices available from qualified laboratories.
  • If you hire someone to do the test, hire only a qualified individual. Some states issue photo identification (ID) cards; ask to see it. The tester's ID number, if available, should be included or noted in the test report. NEHA-NRPP provides laminated ID cards to its certified individuals.
  • The test should include method(s) to prevent or detect interference with testing conditions or with the testing device itself.
  • If the house has an active radon-reduction system, make sure the vent fan is operating properly. If the fan is not operating properly, have it (or ask to have it) repaired and then test.
  • Closed-house conditions means keeping all windows closed, keeping doors closed except for normal entry and exit, and not operating fans or other machines which bring in air from outside. Fans that are part of a radon-reduction system or small exhaust fans operating for only short periods of time may run during the test.

During a Radon Test:

  • Maintain closed-house conditions during he entire time of a short term test, especially for tests shorter than one week in length.
  • Operate the home's heating and cooling systems normally during the test. For tests lasting less than one week, operate only air-conditioning units which recirculate interior air.
  • Do not disturb the test device at any time during the test.
  • If a radon-reduction system is in place, make sure the system is working properly and will be in operation during the entire radon test.

After a Radon Test:

  • If you conduct the test yourself, be sure to promptly return the test device to the laboratory. Be sure to complete the required information, including start and stop times, test location, etc.
  • If an elevated level is found, fix the home. Contact a qualified radon mitigation company about lowering the radon level. EPA recommends that you fix the home when the radon level is 4 pCi/L or more.
  • Be sure that you or the radon tester can demonstrate or provide information to ensure that the testing conditions were not violated during the testing period.

Colorado Radon Testing

It's quite encouraging that more and more people are taking radon gas testing more serious. Maybe the agony it has caused many is the main source of this awareness. Nevertheless, we should not take chances when it comes to this gas and actually we should ensure that the test is done in our homes either by professionals or doing it ourselves with a home test kit.

Even though the home test kits are helpful, we definitely need the help of a special laboratory for analyzing the results of the test. One thing that is noticeable is that the levels of this gas can change depending on the weather. For instance, in winter the levels tend to be much higher while in summer the levels are quite lower. Nevertheless, if you live in a house that is third floor and upwards, then the risks are quite minimal.

When it comes to radon testing, devices that require longer periods of time in testing are more reliable and accurate. The reasoning behind this is that, radon levels change depending on the seasons and thus this devices that are long-term are able to get the average gas value of different seasons. Nevertheless, the minimum time that you need to expose the kit may carry depending on the device that you have.

On windy and stormy days Colorado radon testing might not be reliable and thus it's advisable for one to check the weather forecast before carrying out the test. However, if you prefer to go for short-term testing, then you should ensure that you keep all the windows and doors closed for about twelve hours before you start the test. This way, you'll be able to get accurate results.

Should You Test for Radon?

(Source: Chris Robertson)

Most people don't think much about Radon, and yet Radon can have a major impact on their health and that of their families. That's because Radon can seep into homes and contaminate the air inside. That's a major reason for concern as Radon is a major cause of lung cancer, second only after cigarette smoking. In fact, the US Environmental Protection Agency estimates that there are over 20,000 deaths in the United States every year due to exposure to Radon. How are we getting exposed to Radon, and what can a homeowner do about it?

Radon is a gas that is formed naturally when uranium in rock, soil and groundwater breaks down. The Radon gas then finds its way up to the surface. Unlike other forms of pollution or dangerous gasses, you can neither see nor smell Radon. Most of the time, Radon harmlessly dissipates into the atmosphere outdoors, as it has for millions of years, and it isn't a problem at all. It does become a problem when it finds its way into your house. How can that happen?
In many ways. What happens is that the Radon gas in the soil under your home collects in the void and air spaces under the foundation slab and gradually enters the home. It can also enter through cracks in foundations or even through showers and drainage sumps. Most new homes have much better insulation than in the past, of so the Radon gas becomes trapped indoors. So in this case the better insulation and sealing actually works against you. What can be done to fix a home with a Radon problem?

There are two basic ways to handle the problem. One of them is to install pipes that suck the Radon gas away from the spaces beneath the foundation and harmlessly expel it to the outside above the roof via an electric fan connected to exterior pipes. Another is to run the pipes inside the house or the garage so that the Radon is expelled outside above the roof. In this case, the electric fan is located in the attic, so the components of the system cannot be seen from the outside of the home. Both of these methods are referred to as Radon reduction or "mitigation" systems. According to Jamey Gelina, a radon specialist with The Air Quality Control Agency, "Radon gas can be reduced to safe levels in practically any home when the proper mitigation techniques are applied."

How do homeowners know whether or not their house is exposed to Radon? That's where Radon testing comes in. Radon occurs all over the United States, so testing should be pretty much mandatory. Testing is fairly simple and can be done by qualified testing services that install a detection device and then examine the results after a few days. This will reliably determine if the Radon levels in a home are high enough to require a Radon mitigation system. About one in every 15 homes in the US has excessive Radon levels, and Radon testing is mandatory in many states when you buy or sell a home. Even if it's not, given the potential health risks, it's foolish not to test one's home.

If testing reveals elevated Radon levels, a Radon mitigation system must be installed. Installation isn't difficult and it's a proven and effective technology, but it must be done right. There are many qualified mitigation system installers with certified and licensed technicians, so pick someone who's been in the business for a while to remove this potentially deadly thread from your home.
