GUIDELINES AND POLICIES FOR EXPOSURE TO ELECTROMAGNETIC FIELDS

GUIDELINES AND POLICIES FOR EXPOSURE TO ELECTROMAGNETIC FIELDS

The establishment of exposure limits for EMF radiation by countries and international organizations has now become a necessary and integral part for the protection of the population. The International Commission on Non-Ionizing Radiation Protection (ICNIRP), recognized by the World Health Organization (WHO), has issued exposure guidelines used by most European countries. In 1998, ICNIRP proposed guidelines for the drafting of the current standard that were adopted by the European Commission for Electromagnetic Standardization (CENELEC - Commission European de Normalisation Electrotechnique) and the European Council. In 2018, ICNIRP - based on existing studies - announced a draft of new guidelines, in which the exposure limits at the current frequencies of the 2G, 3G, 4G and 5G systems are almost the same as in 1998. Greek legislation is based on ICNIRP guidelines. The exposure limits are based on scientific published literature, as well as results on short-term exposure.

Reference levels for electric and magnetic fields from 0 Hz - 300 GHz, according to the 1998 version of ICNIRP.

Frequency Band Average SAR (whole body) (W/Kg) Local SAR (head and torque) (W/Kg) Local SAR (extremities) (W/Kg)
100 KHz – 10 GHz 0,08 2 4

The table refers to frequency bands from 100 kHz - 10 GHz as defined by ICNIRP regarding the energy absorbed by the tissues. For the other frequency bands the Special Absorption Rate is considered negligible.
