The compact Radiation Alert GammaView Detector is light, easy to carry and operate with a 1×1 Nal scintillation detector that accurately  measures gamma contamination and exposure. Perfect for use in the lab, facility, and in the field.

The GammaView can also be used as a single-channel analyzer (SCA). This function allows a “window” to be set to focus on a specific energy region of the gamma spectrum, effectively reducing the background count.


Each GammaView includes bluetooth, 2 AA batteries, boot, USB cable, software and is NIST calibrated
