A Practical Guide to Non-Ionising Electromagnetic Fields and Radiation Assessments (2 Revised edition)

This report is a new and updated version of the report 99-0001 that was written in January 1999.

It gives an easy to understand, practical interpretation of the National Radiation Protection Board (NRPB) statement on restrictions on human exposure to static and time varying electromagnetic fields (EMF) and radiation, and includes a section on NRPB-R301 1998.

In addition to this update is a new section on hazards to flammable atmospheres.

The report is presented in three main sections covering the following topics: a review on the NRPB's guidelines of 1993 and also the 1998 ICNIRP guidelines major factors that govern the coupling and absorption of EM energy into the human body, the information required by the site surveyor in order to make the initial calculations and comparison of the measured EMF paramenters with the investigation levels, to name a few ERA's proposals for the procedures required to perform the site survey and the fuller assessment if the investigation or the reference levels have been changed.

Two other effects of radio frequency radiation are discussed, ignition of flammable atmospheres and initiation of electro-expolsive devices. Some benefits provided in this publication are: an easy to understand review of the NRPB's document; the differences between the NRPB and the two-tier ICNIRP guidelines; application of the NRPB's investigation levels and basic restrictions for compliance with the measured EM field parameters.
