Effects of controlled environment on field strength of spurious electromagnetic radiations

Statement of the problem

Occurrence of spurious electromagnetic radiations within the environment of radio navigation systems poses long term health hazard to operators of these systems in aviation. Studies have shown that effects of these spurious microwave radiations on human beings depend on a number of factors, one of them being the intensity of their electromagnetic fields. Various methods have been applied to minimize or even eliminate these microwave radiations. However, one method which has not been exploited involves controlling the intensity of spurious radiations by varying selected environmental parameters around the radio equipment that is generating harmful emissions. These parameters include temperature and humidity. Variation of temperature and humidity separately and simultaneously is likely to affect the electromagnetic field strength of spurious radiations within the controlled environment. The research will be looking for controlled environmental parameter points where intensity of spurious radiations is minimal or within the OSHA recommended safety levels. Thus, it may become possible to dilute harmful radiations and aim to render their effects on equipment operators insignificant.
