RADHAZ (Radiation Hazard) Testing

TRaC has considerable experience in conducting Radiation Hazard (RADHAZ) testing on both Military and Commercial systems. Using high-spec isotropic field probes we can determine the radiated field strength surrounding a transmitter or installation to ensure that co-located personnel are not exposed to levels in excess of the International Radiological Protection Board Guidelines, which now form part of European Health and Safety Law.

TRaC recently conducted testing of all transmitters on a suite of military vehicles using the latest MOD guidelines as laid down by LandRadhaz/Guide/A002/2012 and the levels within JSP 392 leaflet 35. These documents stipulate increased antenna positions and frequencies as well as, where possible, conducting RADHAZ testing on an open area test site (OATS). TRaC has, through its relationship with Millbrook Proving Ground, been able to develop an OATS at a secure facility. This can be used to perform RADHAZ testing of military systems open site in accordance with the new guidelines (assuming frequency clearance can be acquired).  

If full vehicle RADHAZ testing is required to be performed in an anechoic chamber, the Heavy Vehicle Semi-Anechoic Chamber (HVSAC ) at Malvern can comfortably accommodate a Mastiff vehicle with HF antennas fitted and has recently been fully refurbished to improve its overall performance as well as increasing headroom for large vehicles.  

Where a transmitter is found to exceed the reference levels, TRaC is able to conduct Specific Absorption Rate (SAR) testing to determine how much radiation would actually be absorbed be a human operator utilising the equipment.
