Gamma radiation fields are found in many industrial situations, including power generation, nuclear fuel processing, research, industrial radiography and medicine.

The training of staff to understand ionising radiation and to safely monitor areas where it may occur, has presented trainers with a dilemma - exposure of trainee and trainer to radiation is essential if real instruments are to be used to demonstrate its characteristics, but in doing so the staff present receive an unnecessary exposure.

To overcome this difficulty, STS has developed GAMMA - a simulation system that enables very realistic training to be given in many aspects of radiation field training, but without the use of real sources.

Gamma Technology

This STS system uses a radiofrequency source, concealed in a camouflaged container, to simulate the radiation source. The simulated instrument uses a sophisticated detector to measure the RF signal from the source, and this is then displayed on the meter, in appropriate units. Because the instrument responds DIRECTLY to the signal from the source, the system provides an extremely realistic simulation.
  Two major benefits arise from the use of radio signals in this way - the system obeys the inverse square law, thus simulating ionising radiation, and secondly, the shielding properties of materials affects the simulated radiation in a similar way to ionising radiation.
   
  Field Survey Instruments - 900 Series
   
  Simulators for field survey instruments have been developed by STS, and have exactly the same controls, displays and functions as real instruments. Models currently in production include the Eberline RO2, Wallac RD10, Mini Instruments Smart Ion and NETechnology PDR series.
