Título Guidance on determining compliance of exposure to pulsed and complex non-sinusoidal waveforms below 100 kHz with ICNIRP guidelines
Resumo The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has published guidelines for limiting exposure to electric, magnetic and electromagnetic fields (ICNIRP 1998a, b) and has provided frequency dependent basic restrictions and reference levels from which a hazard assessment for exposures to electric and magnetic fields can be made. This document provides clarification for assessing compliance with the guidelines for pulsed and complex non-sinusoidal waveforms with frequency components predominantly up to 100 kHz. The approaches described may be helpful to product standards setting bodies concerned with metrology. In the frequency range up to 100 kHz there are a number of sources of non-sinusoidal magnetic fields with the potential to exceed the reference levels for exposures specified in the ICNIRP guidelines. Common sources include electronic article surveillance gates, demagnetizers, electronic security systems, and metal detectors, and these generate predominantly magnetic fields. Therefore, this statement focuses mainly on magnetic fields; however, this can be readily extended to electric fields.

Título Interim Guidelines on Limits of Human Exposure to Airborne Ultrasound
Resumo These guidelines are primarily aimed at protection against exposure from devices emitting limited to frequencies having one-third-octave bands and guidance is given on limits of human exposure to airborne acoustic energy in the ultrasound range. Adverse health effects of exposure to airborne acoustic energy at levels normally encountered have been reported only at frequencies below 100 kHz and nearly all below 50 kHz. Thus, this standard has been limited to frequencies having one third-octave bands with mid frequencies from 20 kHz to 100 kHz.

Título Intermediate Frequencies (IF)
Resumo A relatively small number of studies has been conducted on the biological effects or health risks of IF fields. This is due, in part, to the fact that fewer types of devices produce fields in this frequency range. But because these devices now have a high consumer and industrial market penetration, it is important to evaluate their impact on human health. This information sheet addresses the known health effects of IF fields, and offers recommendations for further study.

Título INTERSUN - The Global UV Project - A guide and compendium to reduce the burden of disease resulting from exposure to UV radiation while enjoying the sun safely
Resumo This document is intended for national and local authorities and non-governmental organizations (NGOs) active in the area of UV radiation and sun protection. It highlights INTERSUN’s priority activities and publications. The purpose of this document is to provide information from INTERSUN that can be used to develop and implement integrated public health programmes, which reduce health risks from excessive UV radiation exposure. An important objective is to facilitate the harmonization of national activities and coordination of international activities through the use of the Global Solar UV Index and its associated health protection messages.

Título Manual for Measuring Occupational Electric and Magnetic Field Exposures
Resumo The purpose of this manual is to assist investigators in developing methods for occupational exposure assessments for electric and magnetic fields (EMF). Scientific reports that associate EMF with increased risks of various diseases have led to exposure assessments for the purposes of research, source assessment, and the surveillance of worker exposures. To provide guidance for these studies, methods that have been used successfully to measure EMF are summarized and presented in a standard format. The scope of the manual is methods for measuring occupational EMF with frequencies below 30 kHz. This covers most fields resulting directly from DC or 50/60 Hz AC electricity, as well as common electric and electronic equipment such as Video Display Terminals (VDT). In this manual, exposure assessment protocols are classified either as complete methods or partial methods. Complete methods are sets of instructions for the sampling strategy, calibration, measurement, data management and calculation of EMF exposure metrics. The exposure metric and other information about the method are contained in a summary table accompanied by a critique of the method’s strengths and weaknesses. Partial methods are essentially parts of a full method that emphasize important aspects of EMF exposure assessments: sampling strategies, spot measurement surveys, personal monitoring, area monitoring, measuring EMF characteristics, measuring EMFs from sources, walkthrough monitoring, quality control, calibration, data management, and calculating exposure metrics. By combining aspects of these complete and partial methods, industrial hygienists and other investigators can assemble protocols specifically tailored to assess EMF exposures for different purposes, applications, and work environments.
