Abstract
Accurate monitoring of radon requires that the measuring instrumentation be properly calibrated against a recognized standard. The most recent intercomparisons have been conducted using radon-in-air samples contained within spherical glass ampoules provided by the National Institute of Standards and Technology (NIST). These bulbs are now generally accepted as a primary radon calibration standard. In intercalibration exercises using these bulbs, results reported by the U.S. Bureau of Mines (USBM) were found to be in excellent agreement with those reported by NIST. The USBM method of calibration is described, and possible sources of uncertainty examined.
