Radiation Alert Monitor 4

The M4 is a compact, ergonomic, general purpose survey meters 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.

Energy Sensitivity: 1000 CPM/mr/hr (Cs137).

Detects alpha down to 2.5 MeV; typical detection detection efficiency at 3.6 MeV is greater than 80%. Detects gamma and x-rays down to 10 keV typical through the window, 40 keV minimum through the case.

Includes:

  • Carrying Case w/ Belt Clip
