E-PERM^® System

Electret Ion Chamber Technology

E-PERM^® is EPA Accepted

• E-PERM is the first and only radon monitor incorporating Electret Ion Chamber Technology. E-PERM is tested, accepted, and listed by the U.S. EPA, and is nationally recognized as the state-of-the-art technology in the radon measurement industry.
• E-PERM is designated by the EPA as the “EIC, EP, or EC” method.
• The EPA has listed more successful tests using E-PERM (397) than any other method. In fact, 94% of all of the 1989 EPA RMP Round 6 E-PERM entries passed; more so than any other technology.

E-PERM’s^® Performance is Unsurpassed

• System error is less than 8%.
• E-PERM is a true radon integrating method, able to detect any variation in radon concentration, with excellent precision.
• E-PERM is not affected by humidity or normal temperature variations.
• E-PERM is the most popular method for radon testing. New users are added every week.

The E-PERM^® System is Versatile

• The simplicity of operating the E-PERM System is unique to electret-ion chamber technology. There is nothing else like it!
• E-PERM performs both short-term and long term measurements. Long-term electrets during follow-up measure- ments; chambers and measurement equipment perform identically in either case.
• Measurement results can be determined in the field, on-site.
• E-PERM can provide accurate screening measurements within two days. The length of exposure is not limited; the longer the exposure, the better the representation of radon levels over time.
• School personnel can be trained to assist in testing the facilities, or in developing programs to perform the entire testing activity with an in-house E-PERM System. E-PERM is the only technology to offer the options of partial or complete in-house measurement capabilities.

E-PERM^® is Cost Competitive

• The measurement costs will vary with the number of tests, which are a function of the test duration and radon level. In most situations, E-PERM costs less per measurement than any of the applicable methods, such as charcoal absorption and alpha track. E-PERM is more than competitive because its accuracy and efficiency are bonuses.
• There are many excellent radon measurement and engineering firms who specify E-PERM as their choice for accurate, cost effective surveys.
• E-PERM is specified in winning bids throughout the world.
