Spear, W G

A 17-pound, semi-portable, scintillation, transistorized alpha monitor was designed and fabricated, The instrument has both a loud-speaker and a count- ratemeter output indication. The count-rate-meter ranges are 0-1000, 0-10,000, and 0-100,000 C/M with an average probe geometry for Pu/sup 239/ alpha particles of about 18 per cent. The background count-rate is stable at less than three C/M for weeks at a time with no adjustments necessary. All transistor circuits are of the plug-in, interchangcable, printed circuit type. The loudspeaker volume output is sufficient for most plant locations, This instrument was designed primarily for alpha detcction but it may be converted to beta-gamma or neutron detection by proper crystal detector selection.
