| GD100 Gamma GM Detector |
| The GD100 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 GD100 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. |
| The GD100 will detect gamma radiation from 80
keV to 2 MeV with a linearity of ±20%. |
| The detector provides a dynamic
range of 10 µR/hr to 10,000 R/hr. The GD100 is electrically connected via a multi-conductor
shielded cable to an associated Apantec’s
RDM-series Display and Control unit. |
| The GD100 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 GD100. |
