Passive Radiation Detection Warning Device requires no modification whatsoever to the existing metal detector walk-through gates

The Passive Radiation Detection Warning Device – PRDWD radiation detector can convert any existing metal detector walk through gate into a radiation detector. The detector can be installed as a remote detector driven by the power of the main unit or can be installed by utilising an external 5 volt power supply.

The detector is capable of triggering a relay or a switching device, warning light or buzzer. All these operations can be triggered simultaneously or consecutively.


  • Detects and indicates the presence of ionising radiation products of the man-made type known as radioisotopes or radionuclides including x-rays (ionising radiation). PRDWD does not detect non- ionsing radiation, such as mobile telephones, microwaves, radars, etc.
  • Can also operate in conjunction with biometrics
  • access control.
  • Free of modifications on the existing metal detector walk-through gates
  • The relay can be used for monitoring and control with
  • security systems, PLC, strobe lights or buzzers.
  • Gammasonics
  • Alarm to indicate counting event in the detector
