Development of a Rapid Response Radon Monitor.
NTIS: PB/80-183924 :69 pages
A rapid response radon monitor capable of accurately responding within 3 min 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 lb and is capable of 8 hours of continuous protable operation with a self-contained, rechargeable battery power source. Residual chamber contamination from a radon level allowed to remain in the chamber for 90 min is about 10 pct, 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.
