On the other hand, significant relationships were found between work experience and reverse digit span ( P < 0.001), word recognition ( P < 0.001) and paired words ( P < 0.001). On the other hand, work experience and the distance from the antenna played no role in mean GHQ-scores of the participants.Ĭhi-square test showed statistically significant relationship between work experience and forward digit span ( P < 0.001). As shown in Table 3 the number of work hours per day could not affect the GHQ-28 scores of participants. In response to this question that if they have been able to enjoy their normal day-to-day activities (Question#21), 31% responded “less than usual”. Considering been getting edgy and bad-tempered (Question#11), 32% responded “rather more than usual” and 7% responded “much more than usual”. Regarding feeling constantly under strain (Question#10), 37% responded “rather more than usual” and 10% responded “much more than usual”. On the other hand, in response to this question that if they had difficulty in staying asleep once you were off (Question#9), 20% responded “rather more than usual”. Regarding feeling of tightness or pressure in their head (Question#6), 24% responded “rather more than usual”. In response to this question that if they have recently been getting any pain in their head (Question#5), 29% responded “rather more than usual”. In response to this question that if they have recently been feeling run down and out of sorts (Question#3), 31% responded “rather more than usual”. Thirty percent of the participants have reported that rather more than usual they had recently been feeling in need of a good tonic (Question#2). The GHQ scores for social dysfunction and severe depression were 1.08 ± 0.34 and 0.44 ± 0.52, respectively. The mean score of GHQ in all subsets was 0.44 ± 0.52 while these scores for somatic symptoms and anxiety/insomnia were 1.03 ± 0.49 and 0.99 ± 0.58, respectively. Mean (±SD) GHQ-28 scores of participants in all subsets and the scores in each subsection of somatic symptoms, anxiety/insomnia, social dysfunction, and severe depression are shown in Table 2. The aim of this study was to assess if occupational exposure of military radar personnel affect their general health. In a 40-year controlled longitudinal Belgian study, no increase in all-cause mortality in military personnel who were in close contact with radar equipments was found. On the other hand, there are published reports that could not show any detrimental effect in radar workers. There are also reported risks such as increased incidence of hemolymphatic cancers that can be caused by microwaves generated by radars or ionizing radiation produced by electronic devices producing the microwaves. Furthermore, some non-EMF hazards such as radar equipment-related electrical injury are also reported. increased concentration of malondialdehyde), reduced fertility, increased level of DNA damage and chromatid breaks. Recent studies conducted on the health effects of occupational exposure to military radar radiations indicate some detrimental effects such as induction of oxidative stress (decreased glutathione concentration vs. As radiations emitted by radar systems must travel long distances to detect objects, the power must be relatively high at transmission site. Nowadays, radar systems, which operate at RF between 300 MHz and 15 GHz, are widely used for navigation, aviation, national defense, weather forecasting, and even speed control (hand-held police radars). Radar workers are routinely exposed to pulsed high frequency electromagnetic fields (EMF), which are produced to locate and identify the presence, direction or range of airplanes, ships, control towers or other, usually moving objects. Radio Detection and Ranging (Radar) equipments send and transmit high-power radio frequency (RF) waves by producing a high-voltage and high frequency alternating electrical current. The rapidly increasing use of microwave radiation, has raised public concern about possible detrimental effects of non-ionizing radiation sources, which work in this frequency range.
