A four-parameter measurement system to accurately determine the relative humidity, temperature, mine pressure, and ventilation velocity has been developed for use in the radon gas control research of the federal Bureau of Mines. The new unit is housed in a 17- by 20- by 8-inch suitcase weighing less than 15 pounds. Radon gas seepage into mine ventilation systems and into work areas having marginal ventilation is a major problem to the uranium mining industry. The Bureau of Mines, in its effort to reduce this gas hazard, has been working with various sealants and sealant applicators to seal the gas in the surrounding rock. To provide a realistic evaluation of radon gas release rates, the temperature, pressure humidity, and ventilation velocity must be known.
