Analog Radiation Detectors

Numerous industries have put The Monitor 4 Family of analog radiation detectors to the test by decades of use. Radiation Alert® models of analog Geiger counters are an ergonomic, compact alternative to the “lunchbox” style. Great sensitivity, fast response, all in your pocket. Our handheld Geiger counters make spot surveys quicker with audio click and red light response with every count.

Monitor 4 and Monitor 4EC analog Geiger counters detect alpha, beta, gamma, and X-ray. The Monitor 4EC is an energy compensated version, giving a linear response to gamma and X-ray (above 40 keV) radiation through the side wall of the detector.

The MC1K detects gamma and x-ray, offering a linear response with the energy compensated detector. There is no alpha window on the MC1K. When you need an analog high range meter, this is the choice.



Monitor 4

The Monitor 4 is compact, analog radiation detector. A general purpose survey meter capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges. Proven and reliable over decades of use in the industry, the Monitor 4 has evolved into one of the best analog radiation detectors of today. Simple and ergonomic , a red count light flashes and a beep sounds with each count detected. Battery check and silent operation with the flick of your thumb. …

Monitor 4EC

The Monitor 4EC is an energy compensated, ergonomic radiation survey meter capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges.  A red count light flashes and a beep sounds with each event detected. The Monitor 4EC offers a linear response for gamma and x-rays (above 40 keV). …

Monitor MC1K

The MC1K is an ergonomic handheld survey meter using a built-in energy compensated GM detector. It detects gamma and x-rays up to 1000 mR/hr over 4 selectable ranges. The energy compensated Geiger counter affords the detector a more linear response to gammas and x-rays over the full range. A beep sounds and a count light flashes with each event detected.  …
