STS Safe-FH40GL10
Simulated Survey Meter
The STS Safe-FH40G series of simulators. The FH40G is available as a hand held unit or mounted on a telepole for distance working.
The unit developed by STS utilises the STS Safe-Series technology to safely replicate radiation fields. A radiofrequency source, such as those shown, is placed in the training area and the simulated unit activated, the instrument then functions exactly as the real instrument does but is detecting the radio field not ionising radiation.
The simulators are able to replicate characteristic shielding and approximation to the inverse square law providing a very realistic training platform.
The use of simulators also helps to limit the exposure of the trainer – if real sources are used, every training session poses an additional cumulative dose to the trainer, while the trainee receives only the dose resulting from the session attended.
The telepole detector head has detectors mounted inside giving a full 360 degrees of coverage. The STS Safe- miniature source is particularly good for use with the extended telepole as it may be hidden easily out of sight. The FH40 controls and characteristics remain unchanged from the real instrument, button function is identical and the instrument has selectable alarm functions and audio output. The simulator is identical in size and form. The simulator runs on standard 2 AA cells as with the original instrument.
Attenuation of materials may be shown by placing the meter behind various shields such as plaster board, wood & glass. The thickness and density of the material will vary the signal received and demonstrate the value of using shielding to protect the worker.
