| GG1W Gamma GM Detector |
| The GG1W Intelligent Gamma Probe
is an integrated real-time Gamma radiation-monitoring
device that provides highly accurate indication
of ambient Gamma radiation over a wide range. |
 |
The GG1W uses a pair of
halogen quenched Geiger Mueller tubes for sensitivity
to ambient gamma radiation levels. The GM tubes
are operated using a “Time-To-Count”
method which removes the limitations associated
with traditional ‘constant bias’ GM
tube circuits. |
| Detects gamma radiation from 80 keV to 2 MeV with a linearity of ±20%. |
| Dynamic range of 10-4 mSv/h to 105 mSv/hr. |
| Electrically connects via a multi-conductor shielded cable to an associated Apantec's RM1-series Display and Control unit. |
| The GG1W is housed in a rugged cylindrical aluminum housing with a NEMA4 rating. When provided with an internal check source, the detector is designated as Model GG1WC. |
