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...
متن کاملLaboratory Intercomparison of Radon-in-water Standards
The standardization of instruments used for radon-in-water measurements typically involves handling and disposal of Ra in solution. To avoid contact with the Class A carcinogen, radium-free solutions were prepared and tested for use as radon-in-water standards. Filters containing known amounts of Ra were sealed in polyethylene and placed in vials filled with distilled water for >30 days to allo...
متن کاملResults of the 2015 national indoor radon intercomparison measurements
It is well known that radon and its short-lived progenies have the most impact to the population effective dose from radioactive sources [1]. Precise and accurate radon monitoring results should be the basis for the establishment of the national reference level and implementation of radon action plans. During the period February and March 2015, Laboratory for Radioactivity and Dose Measurements...
متن کاملResults 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...
متن کاملThe present status of the radon program in the United States of America.
The indoor radon program in the US. started in the early 1970's in response to Congressional Hearings that recommended the initiation of radon measurements in certain parts of the united States where enhanced radon caused by contaminated uranium and radium tailings was suspect. In the mid 1970's, the Department of Energy (DOE), Environmental Measurements Laboratory (EML), conducted the first in...
