Instrumentation for Measuring Uranium Miner Exposure to Radon Daughters.
Chap 51 in "Radiation Hazards in Mining: Control Measurement and Med Aspects" PP 332-338 :332-338
The U.S. Bureau of Mines has investigated instrumentation and methods for measuring exposure to radon daughters in underground mine atmospheres. Both personal and area monitors have been studied through in-house and contract research. A field study in uranium mines identified some reliability problems that required additional work for the personal dosimeter systems. Improved versions of continuous working level detectors have been developed and tested for use as area monitors in underground mines. Test results for the personal and area monitors were satisfactory for underground mine applications.
