Description

The National Radon Safety Board (NRSB) is working with the US EPA Radiation and Indoor Environments National Laboratory in Las Vegas to conduct an on-site intercomparison for Radon Chambers for radon progeny (Working Level) devices. If you are interested in participating, please contact the NRSB office in Colorado by letter or e-mail. An application for Secondary Radon Chambers is available on-line.

The radon chamber accreditation program is the part of the radon program that ensures that providers of quality assurance exposures of devices and instruments that measure radon and radon decay products meet standard criteria to ensure high quality in their services. Quality assurance exposures include calibrations, spikes, proficiency tests and performance evaluations. Quality in these services is essential to the radon testing industry, because the radon chamber operators provide the reference upon which radon and radon decay product measurements are based. To achieve an adequate degree of quality, radon chambers must meet certain design and operating characteristics.

A secondary radon chamber is one that meets the requirements of this document, and specifically inter-compares with a primary reference, such as the EPA radon laboratory in Las Vegas. A secondary chamber can perform quality assurance exposures of devices including calibrations, spikes and proficiency tests.
