Dose Rate Alarm Unit Graetz GammaTest C

 

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.

Dose Rate Alarm Unit Lamp Graetz GWL 10m

 

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
  • Technical Data
    Type of radiation: gamma radiation / X-rays (DC installations)

    Acoustic alarm: > 93 dB(A) measured in 30 cm distance,
    can be switched off
    Energy range: 40 keV - 1,3 MeV
    Temperature range: -30 °C up to +60 °C
    Power supply: accumulator
    (operating time with fully charged accumulator approx. 48 hours, without acoustic alarm)
    Housing: aluminium combined with high impact plastic
    protection class IP 65
    Dimensions / Weight: (120 x 120 x 250) mm / approx. 2300 g

     

    Dose Rate Alarm Unit Graetz GammaStart

     

    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.

     

    Technical Data
    Type of radiation: gamma radiation / X-rays
    Detector: GM-tube
    Sensitivity: counting rate at 3 µSv/h approx. 1 count/min
    Acoustic Alarm: > 85 dB(A) measured in 30 cm distance
    Temperature range: -30 °C up to +60 °C
    Power supply: 3 batteries type LR1 1,5V
    Housing: aluminium
    Dimensions / Weight: (130 x 50 x 20) mm / approx. 150 g
