Certified Performance Test Chambers

The NRPP requires that operators of analytical radon and/or radon decay product measurement devices periodically pass a device performance test.

Device performance tests are to be conducted at NRPP certified performance test chambers. To become certified as a performance test chamber, a firm must submit and application and pass an inter-comparison test with an independent chamber (currently US EPA in Las Vegas, Nevada).

A certified performance test chamber is certified for radon or radon decay products separately. To view a list of current NRPP certified performance test chambers select one of the following options:

Chambers certified for performance testing radon measurement devices
Chambers certified for performance testing Working Level devices - none at this time

Note: Certified performance test chambers also offer spiking services as required by Quality Control/Quality Assurance.

Tertiary/Calibration Test Chambers

Chambers Certified for calibration and spiking.
