Workers in certain occupations such as the military may be exposed to technical radiofrequency radiation exposure above current limits, which may pose a health risk. The present investigation intended to find the effect of chronic electromagnetic field (EMF) exposure from radar on plasma catecholamines in the military workforce. In the study, 166 male personnel selected randomly were categorized into three groups: control ( n = 68), exposure group‐I (X‐band, 8–12 GHz, n = 40), and exposure group‐II (Ku‐band, 12.5–18 GHz, n = 58). The three clusters were further divided into two groups according to their years of service (YOS) (up to 9 years and ≥10 years) to study the effect of years of radar exposure. Enzyme immunoassay was employed to assess catecholamine concentrations. EMF levels were recorded at different occupational distances from radar. Significant adrenaline diminution was registered in exposure group‐II with no significant difference in exposure group‐I when both groups were weighed against control. Nor‐adrenaline and dopamine levels did not vary significantly in both exposure groups when compared to controls. Exposure in terms of YOS also did not yield any significant alteration in any of the catecholamines and in any of the exposure groups when compared with their respective control groups. The shift from baseline catecholamine values due to stress has immense significance for health and well‐being. Their continual alteration may prove harmful in due course. Suitable follow‐up studies are needed to further strengthen these preliminary observations and for now, exposures should be limited as much as possible with essential safeguards.
