6 MHz–107 GHz
Exposure duration: 6 months to 12 years (duration of employment)
|Frequency||6 MHz–107 GHz|
|Exposure duration||6 months to 12 years (duration of employment)|
|Additional info||Two groups of subjects were examined: The first group included 200 workers employed at installations generating high intensity waves . The second group included 200 controls having no contact to microwave radiation. In each subject from these groups examination with an "Oculus"opthalmoscope and slit lamp was done after prior dilation of the pupil with homatropine or neosynephrine.|
No parameters are specified for this exposure.
The group of 200 workers was compared with 200 persons of a control group.The findings of fundus examination were elaborated statistically. Pathological changes could be found in 84% in the exposed group and in 74% of the control group, respectively. These results demonstrate that there exist a possibility of harmful effects of microwave radiation even at intensities within the limits, if microwave exposure is sufficently long (over 4 - 5 years).
