Abstract

RUGELES URIBE, José de Jesús et al. limits for human exposure to electromagnetic fields in accordance with ITU- k.52 standard for frequencies between 10 khz and 3 GHz in urban areas of Bucaramanga. Ing. Investig. [online]. 2007, vol.27, n.3, pp.149-158. ISSN 0120-5609.

This article presents an overview of the results obtained from testing the limits of human exposure to 10KHz to 3GHZ frequencies in the city of Bucaramanga (Colombia), taking into account decree 195-2005 approved by the Colombian Ministry of Communications, based on International Telecommunication Union (ITU) recommendation K.52. Measuring levels of exposure to electromagnetic radiation at three chosen locations in the city considered to be sensitive did not reveal that exposure limits were being exceeded. Mobile phone, modulated amplitude emission, frequency modulation and television bands installed at the sites several years ago were also measured. Levels obtained from electric field strength exceeded 100 dBuV / m in all cases, maximum value being 139 dBuV / m. Levels were well below exposure limits established by the K-52 rule. The highest levels for the general public’s exposure were 1.74964% in the AM band and 0.006408% for the cellular band between 869 and 894 MHz. This article also contains a description of the modules, exposure limits, acquisition and geo-positioning using the EspecVIEW tool designed for performing several types of measurements by Ministry officials and used in this study.
