Handheld Radiation Alert® Detector, Monitor 4 - SE
International
The
Handheld Radiation Alert Detector is a portable and compact monitor that
detects radiation exposure in almost any situation. It is a battery
operated device which runs on only one 9-volt alkaline battery. With
this monitor there are no external wires or probes.
Features:
- Wireless
- Illumination and audio alerts with detection of radiation
- Geiger
tube
- ABS plastic shell
- Battery
operated
- Detects radiation over three selectable ranges
- Detects
four different types of radiation:
- Ideally used in
- Hospitals
- Research Labs
- Power Plants
- Rescue Units

Monitor Sensitivity:
|
Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV
> 80%.
Detects beta at 50 keV
with 35% efficiency.
Detects beta at 150 keV
with 75% efficiency.
Detects gamma and x-rays down to 10 keV
through the window, 40 keV minimum through the
sidewall.
Normal background is approximately 10-20 CPM.
