Description:"Twelve laboratories from the western United States and Canada participated in radon progeny intercomparison measurements at the U.S. Bureau of Mines radon calibration facility in March 1987. The participants intercompared grab-sampling and automated equipment methods at high and low concentrations of radon progeny and condensation nuclei. The objective of this intercomparison was to determine if the measurement procedures and equipment of the North American facilities are equivalent. The sampling results showed good agreement among all participants. The standard deviation for the working level measurements was less than 3.5 pct for 1.70 Working level (wl) and less than 8.8 pct for 0.21 Wl. This relatively good agreement was achieved by using alpha standards calibrated by the National Bureau of Standards and by closely checking and monitoring airflows." - NIOSHTIC-2
