Abstract :
The instrument described measures the shortlived 222Rn-daughter concentrations and the Working Level (WL) in sealed "hot chambers" located in uranium mines. Radiation-induced pulses from two separate sensors are transmitted through 500 ft. cables to a microprocessor, which processes the pulses and controls the operation of the system. A read-only memory stores a fixed program which is used to calculate the desired concentrations. The results are printed as pCi/l (Rn-daughter concentrations) and WL.
