RESEARCH AND DEVELOPMENT OF AN AUTOMATIC BERYLLIUM-IN-AIR MONITOR
Abstract
An improved model beryllium-in-air monitor was constructed, calibrated and tested in the laboratory. Significant improvements include optimization of the air sample system design and elimination of the temperature instability of critical electronic parts. A concentration of 25 micrograms per cubic meter beryllium-in-air requires 4 minutes for reliable alarming, a low level concentration of 2 micrograms beryllium requires 60 minutes. Sensitivity, alarm reliability and response time are all dependant primarily upon the construction of the alpha source. Other characteristics of the device and instrument design were optimized.
