A survey of radon measurement needs and activities in state radiation control programs

This report summarizes the findings of a survey which was conducted in April-May, 1981 to determine radon measurement needs and present activities in state radiation control programs. The survey focuses on a wide variety of methods for measurements of radon and related quantities. This includes methods for measurement of radon (222Rn) concentration in air, potential alpha energy concentration, individual radon progeny concentrations, radon exhalation or flux density from surfaces, radon concentration in water, and thoron (220Rn) or thoron progeny concentrations in air. The report identifies the sources of radon and thoron which necessitate measurements in the states; the types of measurements and measurement methods that are performed routinely, or that the states would like to obtain or improve the capability of performing; existing calibration capabilities for these measurement methods; and the perceived needs for improving the quality of the measurements
