In recent years, industrial and technological development has led to a remarkable increase in the environment of non-ionizing radiation produced by artificial sources. The increased production and geographical spread of electromagnetic fields may be dangerous for the health of people exposed to them. Therefore, we carried out a survey of low- and high- frequency emission sources, measuring the intensity of the electromagnetic fields and characterising the emission systems in the district of Otranto in southern Italy. The low-frequency electromagnetic fields were measured using a PMM 8053 portable gauge for the frequency interval 5Hz-100kHz, a Wandel & Goltermann EMR 300 portable gauge for the 100 kHz-3GHz frequency interval and a HI-4455 probe for the 200 kHz-40 GHz frequency interval. The results of our measurements showed that the emissions for low and high frequencies were within the limits specified by the regulations in force. The only exception was a radio mast at point n. 10 (Masseria Uliveto) near which a value of 10.1 V/m above both the warning value and the quality target value specified by the Prime Minister’s Decree (P.M.D.) of 8th July 2003. However, these limits must be considered the minimum requirement consistent with the general aim of reducing exposure where technically possible and where conditions allow.

Abstract
In recent years, industrial and technological development has led to a remarkable increase in the environment of non-ionizing radiation produced by artificial sources. The increased production and geographical spread of electromagnetic fields may be dangerous for the health of people exposed to them. Therefore, we carried out a survey of low- and high- frequency emission sources, measuring the intensity of the electromagnetic fields and characterising the emission systems in the district of Otranto in southern Italy. The low-frequency electromagnetic fields were measured using a PMM 8053 portable gauge for the frequency interval 5Hz-100kHz, a Wandel & Goltermann EMR 300 portable gauge for the 100 kHz-3GHz frequency interval and a HI-4455 probe for the 200 kHz-40 GHz frequency interval. The results of our measurements showed that the emissions for low and high frequencies were within the limits specified by the regulations in force. The only exception was a radio mast at point n. 10 (Masseria Uliveto) near which a value of 10.1 V/m above both the warning value and the quality target value specified by the Prime Minister’s Decree (P.M.D.) of 8th July 2003. However, these limits must be considered the minimum requirement consistent with the general aim of reducing exposure where technically possible and where conditions allow.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
