Product Description
The Rad 100 Digital Pocket Geiger Counter
The recent stepchild to the Rad 100, and as in its parent model, the Rad 100 is designed for general purpose monitoring of radioactivity.
The Rad 100 is identical to the Radalert in most every respect. The main difference is that the Rad 100 has no user adjustable audible Alert feature, making possible substantial savings to the consumer.
Like the Radalert 100, the Rad 100 otherwise offers these features:
Detects Alpha, Beta, Gamma and X-radiation Digital readout on large, easy to read LCD display Readings in CPM and mR/hr, or µSv/hr Total mode for timed counts Audible clicking with each radiation count detected (can turn off) No user adjustable Audible Alert (choose Radalert 100X for that) Data Port for connection to computer or data logger Select the navigation button, or click here for detailed Specifications on the Rad 100, except for the audible alert feature.
The Rad 100 is an excellent value for the money, offering good sensitivity in a user friendly Geiger counter with digital readout.
Specifications for the Radalert 100:
Detector
Halogen-quenched, long thin cylindrical Geiger-Mueller tube (LND712) with side wall of .012" #446 stainless steel, and with thin mica end window
Window Size
1.5 to 2.0 mg/cm² thick;
Radiation Detected Alpha, Beta, Gamma, X-ray Sensitivity Detects alpha down to 2.5 MeV; efficiency at 3.6 MeV > 80% Detects beta at 50 keV w/35% efficiency, at 150 keV w/75% Detects gamma and X rays down to 10 keV thru window, 40 keV minimum through case; gamma sensitivity is 1,000 CPM/mR/hr referenced to Cs-137 Normal background is approximately 10 to 20 CPM Accuracy

necessary and easy to use device
through my years of mineral collecting i have borrowed detectors from friends and colleagues. over the past several years, my family has joined in my passion for rocks and minerals. for their safety, and for mine, i am most pleased to have purchased this easy to use, rugged, reliable detector. mark goldgeier on Jun 5th 2019
