Childhood Leukemia Risk Due to High Voltage Transmission Line in Tehran - Iran

摘要

Up to the best of our knowledge, the first report on the relationship between childhood cancer and electromagnetic field emitted from power lines dates back to 1979. In our research, a group of 202 children suffering from leukemia has been studied (as case group). Map of Tehran was divided to 921600 square regions using AUTOCAD software. Using random number generator 4000 square regions were selected of which 86 were located 100 meters or less from the power line (as simulated control group), corresponding to 0.2 μT. Out of 202 children 7 were living in these selected area. Statistical analysis shows that Odds Ratio is equal to 1.63 (95% CI = 0.8 - 3.6) that shows a causal relationship between electromagnetic field and childhood leukemia.
