A study on haematological and physiological effects of electromagnetic radiation from global system of communication

Aim: To study the effects of exposure to electromagnetic radiations from cell phone on Humans. Materials and Methods: A prospective cross-sectional study was conducted in a secluded room of the Central Laboratory of the Medical College where use of electronic devises is prohibited. The study was conducted on 25 healthy male subjects and 25 health female subjects in the age range of 18–25 years of age. In post night fasting state, the study subjects were isolated in the secluded room for 3 hours to prevent any exposure to electromagnetic radiations. Blood sample is collected and divided into two aliquots, one is control sample (not exposed) and test sample (exposed to EMR with strength of 0.471 W/Kg for 30 minutes from a distance of 5cm). The samples were evaluated for blood cell count, blood indices and blood sugar levels. Nerve conduction study was done on median nerve prior to and after exposure to EMR for 5 minutes. Results: Significant increase was observed in Mean Corpuscular Volume (MCV) (p 0.012) and Neutrophil count (p 0.026) in test sample compared to control sample. Significant decrease was observed in Mean Corpuscular Haemoglobin Concentration (MCHC) (p 0.049) and blood sugar levels (p Nerve conduction study on median nerve has shown significant increase in conduction velocity (p 0.014). Conclusion: The study has shown that even a limited exposure to EMR in recommended strengths can cause significant changes in haematological parameters and conduction velocity of nerve.
