摘要

This study was focused on the measurement of residential exposure to power frequency (50-Hz) electric and magnetic fields in the city of Ramallah-Palestine. A group of 32 semi-randomly selected residences distributed amongst the city were under investigations of fields variations. Measurements were performed with the Spectrum Analyzer NF-5035 and were carried out at one meter above ground level in the residence's bedroom or living room under both zero and normal-power conditions. Fields' variations were recorded over 6-min and some times over few hours. Electric fields under normal-power use were relatively low; similar to 59% of residences experienced mean electric fields 10 V/m. The highest mean electric field of 66.9 V/m was found at residence R27. However, electric field values were log-normally distributed with geometric mean and geometric standard deviation of 9.6 and 3.5 V/m, respectively. Background electric fields measured under zero-power use, were very low; similar to 80% of residences experienced background electric fields 1 V/m. Under normal-power use, the highest mean magnetic field (0.45 mu T) was found at residence R26 where an indoor power substation exists. However, similar to 81% of residences experienced mean magnetic fields 0.1 mu T. Magnetic fields measured inside the 32 residences showed also a log-normal distribution with geometric mean and geometric standard deviation of 0.04 and 3.14 mu T, respectively. Under zero-power conditions, similar to 7% of residences experienced average background magnetic field 0.1 mu T. Fields from appliances showed a maximum mean electric field of 67.4 V/m from hair dryer, and maximum mean magnetic field of 13.7 mu T from microwave oven. However, no single result surpassed the ICNIRP limits for general public exposures to ELF fields, but still, the interval 0.3-0.4 mu T for possible non-thermal health impacts of exposure to ELF magnetic fields, was experienced in 13% of the residences.
