Title

ALTERATIONS OF VISUAL REACTION TIME AND SHORT TERM MEMORY IN MILITARY RADAR PERSONNEL (PRELIMINARY REPORT)

Pages

  428-435

Abstract

 Background: Radar transmitters emit high-power RADIOFREQUENCY radiation by creation of a high-voltage and high-frequency alternating electrical current.Methods: HEALTH EFFECTS of OCCUPATIONAL EXPOSURE to MILITARY RADAR were investigated. Visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. To assess the short-term memory, modified Wechsler Memory Scale test was performed.Results: The mean+/- SD reaction time in radar works (N=100) and the control group (N=57) were 238.58+/- 23.47 milliseconds and 291.86+/- 28.26 milliseconds (P<0.0001), respectively. The scores of forward digit span in radar works and the control group were 3.56+/- 0.77 and 4.29+/- 1.06 (P<0.0001), while the scores of backward digit span in radar works and the control group were 2.70+/- 0.69 and 3.62+/- 0.95 (P<0.0001). The scores of word recognition in radar works and the control group were 3.37+/- 1.13 and 5.86+/- 1.11 (P<0.0001). Finally, the scores of paired words in radar works and the control group were 13.56+/- 1.78 and 15.21+/- 2.20 (P<0.0001). It can be concluded that OCCUPATIONAL EXPOSUREs to radar radiations decreases reaction time, which may lead to a better response to different hazards.Conclusion: To the best of our knowledge, this is the first study to show that OCCUPATIONAL EXPOSURE to radar MICROWAVE radiation leads to decreased reaction time and the lower performance of short-term memory. Altogether, these results indicate that OCCUPATIONAL EXPOSURE to radar MICROWAVE radiations may be linked to some non-detrimental and detrimental HEALTH EFFECTS.
