There are many different models of CRMs, too many to discuss in this medium, but they all require some formal training in order to be used properly. Simplicity, ease of use and low cost are the reasons more than 250,000 of the devices are used by the general public each year to test their homes and work places. Their main purpose is for a radon screening measurement by homeowners who want to know if there is a potential radon problem in the home. By far the most popular is a screening test that uses an activated charcoal test kit. We have a page with our charcoal-based test kit , plus complete animated instructions .
Operation is neat, quick and simple.
This same test kit is also carried by most True Value Hardware stores under the American Sensors label. Just click on ordering when it comes up at the bottom of the index column at the left. If you order using your VISA, MC, or Discover card, the kit will be sent via first class mail, usually the same day, and you should have it in less than a week. If you've tested the air in your home and found a radon problem, and your water comes from a well, you should have your water tested for radon. Compared with radon entering the home through soil, radon entering the home through water will in most cases be a small source of risk.
