Description:

The International Intercalibration and Intercomparison Program (IIIP), consisting of several selected laboratories from four countries, held a radon progeny intercomparison measurement at the U.S. Bureau of Mines experimental Twilight Mine on September 12-14, 1988. Grab samples were taken at four different conditions of low and high radon progeny and condensation nuclei concentrations, respectively. The results showed good agreement among all seven participants. The coefficient of variation of all measurements was 4.7 pct; after minor corrections for flows and some systematic biases, it was reduced to 3.2 pct. [Description provided by NIOSH]
