Why should you choose E-PERMs?

Independent Agencies Demonstrate Superior Accuracy With E-PERMs

• The U.S. Department of Energy's 1994 Intercomparison demonstrated that E-PERMs perform as well as the more expensive continuous radon monitors.
• More E-PERM users have successfully participated in the U.S. EPA's Radon Proficiency Programs than any other technology.

E-PERMs Are Widely Accepted

• The U.S. EPA used E-PERMs for measurement of U.S. ambient radon levels for its Citizens Cuide to Radon.
• Chosen by the IAEA for its 60-country global radon study.
• Also used by IAEA for area monitoring following the Chernobyl nuclear reactor accident.
• The U.S. Postal Service and several other large federal government agencies have specified E-PERMs for use in their radon surveys of public properties in the U.S.
• Accepted and used widely in Germany, Italy, Sweden, Switzerland, and South Africa.

E-PERMs Deliver Low Cost Measurements

• Reusable monitors and voltage readers keep your equipment costs down - as low as $1.00 per measurement! The only replacement part is the electret.
• The Radon Introductory Kit eliminates your dependence on outside laboratories. E-PERMs put you in control.
