General
Purpose Beta Monitor
Model GM1 detects
low level beta contamination from radioisotopes commonly utilized
in research laboratories such as 32P, 35S, 14C,
45Ca and 131I. Sensitive GM tube has a
total effective area of 1.125 inches with a window thickness of 1.5-2.0
mg/cm2. Detector includes a unique protective screen
that provides 86% open area for maximum sensitivity. Removable
plastic storage cap protects GM tube when instrument is not in use.
Minimum detection levels for hard beta emitters is 8-4
Ci/cm2 and 10-4 Ci/cm2 for soft beta
emitters. Minimum energy response to gamma radiation is 15 KeV.
The Rad-MonitorTM Radiation Monitor features a built-in battery
charger which allows use of rechargeable batters. Optional AC adapter is available
for 110 VAC operation and battery charging. Instruments are supplied with detector
probe, alkaline batteries, instruction manual and a two year limited warranty.
