| Advanced Survey Meter. |
INTRODUCTION: The ASM-990 series are easy-to-use instruments that detect alpha, beta, gamma, or x-ray radiation within an operating range of 0.1 mR/hr to 1 R/hr or 1 to 5,000,000 CPM, depending on the probe selection. Visual indication of measured values, as well as selectable parameters, are displayed on the analog/digital display. The units are compatible with Geiger-Mueller (GM) detectors and scintillation probes operating from 500 to 1300 volts. APPLICATION: The ASM-990 series are designed to meet the high technology requirements of health physics, medical physics, and nondestructive testing applications. Radiation safety officers (RSO), nuclear medicine laboratories, diagnostic x-ray and hospital emergency room technicians, and environmental health physicists will appreciate this intelligent survey meter with its cell phone-like multi-function key for easy menu navigation. The units, with purchased probe, are shipped calibrated and ready-to-use. With the proper probe combination, this meter can be used as a general survey meter, an area monitor, a wipe test counter, and a contamination monitor. The unit is supplied with an MHV connector to ensure compatability with all Victoreen probes. A Model 992 is available that includes a fully calibrated internal energy compensated 1 R/hr GM detector. The Model 993 features a fully calibrated internal pancake detector as well as an internal energy compensated 1 R/hr GM |  |

GM probes for qualitative radiation detection - The Geiger-Mueller (GM) detectors fulfill a wide variety of radiation
measurement needs for alpha, beta, gamma and x-ray sources. Some probes are provided with a 360° shield to permit
discrimination between penetrating and non-penetrating radiation. The GM detectors have a field-proven design to ensure dependable performance, reliability and ruggedness. Standard MHV type connectors readily allow interchange of all detector probes. The life expectancy of the counters range from 108 total counts to unlimited life depending on the type of quench gas utilized. Enhanced sensitivity to low level alpha, beta, gamma and x-ray radiation is achieved when using the unique 489-110D Pancake GM Probe. The following probe selection guide lists various probes and suggested applications. Applications include nuclear medicine, counter top surveys, leakage detection from diagnostic x-ray and linear accelerators, geological surveys, scrap metal yards and unknown wells. Scintillation probes for quantitative radiation assessment (counts/minute). The scintiallation detectors are optically coupled to photomultiplier tubes, which are then both magnetically shielded with mu-metal and specially shock-mounted to provide trouble-free performance. The entire detector, crystal and photomultiplier, are secured in a sturdy cylindrical aluminum housing. Where appropriate, a thin window has been utilized to provide alpha or low energy gamma response. Applications outlined in this guide include nuclear medicine labs, HAZMAT spills, radiation safety office surveys, industrial hygiene, industrial x-ray manufacturing, and geological surveys. |
