E-PERM® System


Electret Ion Chamber Technology
Decision Maker Fact Sheet


E-PERM® is C-NRPP Listed

  • E-PERM incorporates electret ion chamber technology.
  • E-PERM is tested, accepted, listed by the NRPP, and is internationally recognized as the state-of-the-art technology in the radon measurement industry.
  • E-PERMs have been popular for many years. 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 accurately follow 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-PERMSystem is Versatile

  • The simplicity of operating the E-PERM System is unique to electret-ion chamber technology.
  • E-PERM performs both short-term and long-term measurements. Ion chambers and measurement equipment perform identically in either case. By selecting the appropriate ion chamber and electret type, E-PERM detectors can be deployed from two to 365 days as shown in the table.

  • Measurement results can be determined in the field, on-site.
  • E-PERMs 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 Sper 1 Reader

  • The measurement The measurement costs will vary with the number of tests, which are a function of the test duration and radon level.
    E-PERM costs less per measurement than any of the competing methods.
  • E-PERM is more than competitive because its accuracy and efficiency.
  • 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 many competitive tenders throughout the world.
