Intercomparison of Commercially Available Active Radon Measurement Devices in a Discovered Radon Chamber

A Comparison of ‘radon’ Measurement Devices

Field comparison of commercially available short-term radon detectors.

We performed a comparison of commercially available short-term radon detectors in order to determine the accuracy and precision of the detectors under actual field conditions. We exposed fifteen radon detectors, under field conditions, from each of six companies to a reference radon concentration. Five of the six companies tested did not pass the U.S. Environmental Protection Agency's previousl...

Intercomparison of retrospective radon detectors.

We performed both a laboratory and a field intercomparison of two novel glass-based retrospective radon detectors previously used in major radon case-control studies performed in Missouri and Iowa. The new detectors estimate retrospective residential radon exposure from the accumulation of a long-lived radon decay product, (210)Pb, in glass. The detectors use track registration material in dire...

Response of a Radon Charcoal Cannister to Climatic and Radon Variations in the Inte Radon Chamber

Charcoal canisters are commonly used to measure radon concentration for periods of 2-7 days. The radon absorption and desorption process is known to be sensitive to several environmental parameters such as temperature, relative humidity and radon concentration fluctuation. In the present study a set of exposures under different environmental conditions were done in the INTE radon reference cham...

Results from the First Annual Aarst Radon Measurement Intercomparison Exercise

The First Annual AARST Radon Measurement Intercomparison Exercise was conducted at the radon calibration laboratory at Bowser-Momer, Inc. in November and December, 1997. There were thirty-two participants involved in the exercise, including Bowser-Momer. For grab radon measurements, the Environmental Measurements Laboratory (EML) sent samplers to be filled in the Bowser-Morner chamber simultane...
