The RadAlert-100 Geiger-Muller counter is a breakthrough in price and technology for personal radiation detection and protection. This small unit detects a full spectrum of ionizing radiations, to include x-ray, alpha, beta and gamma, and additionally incorporates an adjustable alarm feature, to automatically alert you to higher-than-normal radiation levels. During normal operation, the counts per minute appear on the digital display, with a flashing red LED and audio chirp (which can be shut off if desired), refreshing each minute. Or it can be set to gather the radiation dose over time if set into the totaling mode. The RadAlert can thereby be used for seeking out radiaiton "hot-spots" or evaluating materials which give immediate strong reactions, or alternatively allow one to make averaging determinations of low level radiation exposures over longer periods. The time-totaling feature is useful when evaluating low-level exposures from devices, materials or locations (as from TV's, CRT's, radiation-containing rocks, or Radon in a basement). One can then compare such timed readings to similar readings made in the open air, from background radiation alone. The RadAlert easily fits into a briefcase, purse, or large pocket, and has a belt clip for easy carrying and access. It operates from an included standard 9 volt battery for easy portable use.
Sensor: Halogen-quenched GM detector tube with mica end window. Detects Alpha, Beta, Gamma, and X-radiation.
Display: 4 digit liquid crystal display with mode indicators
Operating Range: mR/hr: .001-110 mR/hr (1100 micro-Sv/hr). CPM: 0-350,000 (3,500 CPS), or accumulated counts from 1 minute to 40 hours.
Sensitivity: 1000 cpm/mR/hr referenced to Cs-137.
Alert: Pulsating beeper sounds the alert. Alert level is adjustable.
Count Light: Red LED flashes with each count.
Beeper: Chirps for each count (can be muted).
Outputs: Dual miniature jack drives CMOS-compatible devices:
1. Counts to computer or data logger collection systems, such as "Geigergraph" (see below), or Vernier "Logger Pro" (Macintosh or Windows).
2. Can also be used as an audio output to an external earpiece, amplifier, or tape recorder.
Power: 9-volt battery gives 3-6 months continuous use at normal background level.
Size: 150 X 80 X 30 mm (5.9 X 3.2 X 1.2 inches)
Weight: 225 grams (8 oz.) including battery
Operating Temperatures: from 14 - 122 deg. F.
Note: The RadAlert100 is a newer version and replaces the older RadAlert50, which had a more limited measuring range and sensitivity.
* Adjustable audio alert level
* Dose rate or accumulated dose
* Easy conversion to your choice of CPM or mR/hr
* Interface to a computer or data logger
* Interface to an external warning device
