Malignant neoplasms on territories with different levels of magnetic fields of industrial frequency

摘要

The incidence of malignant neoplasms in the territories with different levels of magnetic induction of the industrialfrequency was investigated. The measurement of magnetic induction was performed using an automated complexincluding a laptop, a GPS receiver and magnetic induction testers oriented in accordance with the three components ofthe magnetic field vector. The measured data were subjected to spectral transformation with filtering harmonics of theindustrial frequency, the magnetic induction module was calculated, which was displayed on the electromagneticpollution map of the city. Data on cases of diseases for 2004–2012. were obtained from the cancer registry of the TomskRegional Oncology Center. The incidence was calculated in the territories with low (20–140 nT), medium (141–950 nT)and high (951–2511 nT) values of magnetic induction. An increase in the incidence of malignant tumors has been notedas the induction of the magnetic field produced by overhead power transmission lines increases. According to theWilcoxon test, differences in morbidity are significant for incidence in areas with low and medium levels of magneticinduction at a significance level of p = 0.038; for morbidity in areas with low and high, medium and high levels ofmagnetic induction at a significance level of p = 0.007. The received epidemiological data demonstrate the role ofmagnetic fields of industrial frequency as a risk factor for occurrence of oncological diseases in the population.
