The GammaTest C is a light, robust battery
operated pocket-sized dose rate alarm unit for the personal radiation
protection for the detection of gamma and X-rays. Four different alarm
thresholds can be adjusted. When being exceeded, an optical (red LED) and
acoustic alarm will be triggered.
The dose rate alarm threshold 25 µSv/h is
required by the German Fire Brigades Regulation (FwDV 500) for the
determination of a danger zone. The alarm threshold 40 µSv/h is required in
the range of non destructive testing (NDT) during radiographic processing (for
example by X-rays): the local dose rate outside the control area may not
exceed 40 µSv/h.
The splash-proof, anodically treated aluminium
housing of the GammaTest C ensures a shielding against EMC influence.

The GWL 10m is an accumulator operated dose
rate alarm unit, independent of mains supply, for the detection of gamma
radiation and X-rays. The instrument has four alarm thresholds, triggering
optical and acoustic alarm when being exceeded. The acoustic alarm can be
switched off, if required.
The instrument, designed for operations in
"heavy-duty" environments, is EMC-proof and equipped with a robust and
splash-proof housing. The GWL 10m is preferably used for room monitoring and
for the determination of restricted areas, where a given dose rate has been
achieved.
The GWL 10m is supplied together with a
recharger unit for recharging the built-in accumulator.
Optional accessories:
robust tripod
motion sensor triggering an acoustic alarm when a person approaches
towards a danger zone with increased radiation level

The GammaSmart is a pocket-sized, very
robust, battery-operated dose rate alarm unit for the personal radiation
protection. It is designed for the detection of gamma radiation and X-rays,
indicating these with clear optical and significant acoustical pulse
repetition rate. An increasing dose rate leads to an increasing pulse
rate.
The splash-proof aluminium housing - equipped
with an optical battery control - ensures a shielding aginst electromagnetic
influence: the device is EMC-proof.

The dose rate alarm unit "GammaSmart V.Ex" is
a very robust and easy to handle pocket-sized alarm unit. It is accumulator
operated and designed for personal radiation protection.
It detects gamma radiation and X-rays,
indicating these with clear optical and acoustical single pulses. An
increasing dose rate leads to an increasing pulse rate.
The splash-proof aluminium housing (IP 54)
ensures a shielding against electromagnetic influence. An optical battery
control indicates the GammaSmart's readiness for use.
Recharge of the built-in accumulator requires
the recharger unit "GRAETZ 462L" (necessary accessories)
