Study of non-ionizing radiation emissions in two zones of Xochimilco, México City

Abstract

The objective of this study was to estimate electromagnetic pollution by radio frequency (RF) and magnetic field (CM) over one year by measuring the intensity near schools, hospitals, business premises, and homes in a commercial and a residential zone of Xochimilco, México City. The RF and the CM were measured using an EXTECH® EMF450 meter. We compared the values of nonionizing radiation (NIR) found in the environment with the levels reported to affect the biological systems of both humans and animals. We also compared these values with the limits established both nationally and internationally. The highest average CM and RF values in the central zone were 6.38 μT and 1316 μW/m2, respectively, while in the housing area, they were 5.08 μT and 66 μW/m2. The values we registered were below the permissible limits both nationally and internationally. However, they were above the reported threshold that could trigger adverse health effects according to some authors. These values are within the limits established by the International Commission on Non- Ionizing Radiation Protection (ICNIRP). Further studies are required as there is still nothing conclusive regarding this type of radiation and its effects.
