A rapid response radon monitor capable of accurately responding within 3 minutes to changing radon levels of magnitude from 100 to 10,000 pCi/l (typical of the levels in working uranium mines) was developed for the Bureau of Mines. The 12- by 10- by 6-inch instrument weighs 17 pounds and is capable of 8 hours of continuous portable operation with a self-contained, rechargeable battery power source. Residual chamber contamination from a radon level allowed to remain in the chamber for 90 minutes is about 10 percent, decaying about a factor of 2 in 1 hour. The instrument sensitivity is a nominal 0.1 cpm (pCi/l), with a background count rate of less than 1 cpm.
