Explore the history and potential updates of ICNIRP guidelines regarding radiofrequency electromagnetic fields. Learn about the significance of revising standards, considerations for long-term effects, and the balance between stability and updating. Discover the implications of scientific evidence, new technologies, and the importance of not revising standards for non-scientific reasons. Delve into the evaluation of RF-EMF carcinogenic risks, different protection systems, and the workshop's objectives to develop a consistent framework for radiation protection.

EVOLUTION OF ICNIRP GUIDELINES FOR RADIOFREQUENCY EMF Paolo Vecchia Past Chairman of ICNIRP ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014

BASIC QUESTIONS • How likely is it that the exposure limits for radiofrequency fields will change? • What would be the consequences? • How likely is it that the basic approach to protection will change? • What would be the consequences? ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
EVOLUTION OF ICNIRP GUIDELINES • RF (interim) 1984 • RF 1988 • Time-varying electromagnetic fields > 0 Hz - 300 GHz 1998 Basic features of guidelines have not changed over the time ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
EARLY STANDARDS (1953-1982) ICNIRP 1998 Adapted by Hitchock and Patterson 1995 ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
ARE GUIDELINES OUTDATED? • Guidelines for time-varying fields last updated in 1998 • “Old” does not necessarily mean “not valid any longer” • Long duration is in general a proof of good norms • A balance between stability and updating is needed ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
WHY TO REVISE A STANDARD? • New scientific evidence (new effects, changes in thresholds, refinement of dosimetry) • New technologies (revision of safety factors, possibility of relaxation) • Outdated research database ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
NOT REASONS TO REVISE SCIENCE-BASED STANDARDS • Social pressure • Different regulations issued by national or local authorities • Time passed from last revision ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
CONFIRMATION OF ESTABLISHED EFFECTS It is the opinion of ICNIRP, that the scientific literature published since the 1998 guidelines has provided no evidence of any adverse effects below the basic restrictions and does not necessitate an immediate revision of its guidance on limiting exposure to high frequency electromagnetic fields.

CONSIDERATION OF LONG-TERM EFFECTS [The Interphone data] combined with the results of biological and animal studies, other epidemiological studies, and brain tumour incidence trends, suggest that within the first 10-15 years after first mobile phone use there is unlikely to be a material risk of adult brain tumours resulting from mobile phone use.

THE IARC CLASSIFICATION ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
THE IARC CLASSIFICATION IARC’s evaluation of RF-EMF as “possibly carcinogenic to humans” is not in contradiction with the assessments of ICNIRP and other major scientific organizations (such as SCENIHR (EU), HPA (UK), AFSSET (France), ARPANSA (Australia), HCN (The Netherlands), etc. A correct knowledge and understanding of the IARC classification, and of the different approach and scope of the different institutions is crucial. However, do hypotheses and suggestions of long-term effects justify a different approach to health protection? ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
DIFFERENT PROTECTION SYSTEMS Depending on the effects the appropriate system is chosen: • Health threshold based system Adequate for established threshold effects • Optimization system Adequate for no-threshold known hazards • Precautionary measures Adequate for suspected hazards ANTENNAS, DEVELOPMENT, INCLUSION AND HUMAN HEALTH Lima, Peru, 10-11 July 2014
The main objectives of this workshop are to identify similarities and differences in ionizing and non-ionizing radiation protection principles, in order to develop a reasoned and logically consistent framework The important issue of whether the principles of justification, optimization and limitation that govern ionizing radiation protection can or should be applied for non-ionizing radiation, will be also in the focus. The result of the workshop will flow in the update of the ICNIRP statement on “General approach to protection against non-ionizing radiation”.
