Some useful tools for assessing EMF exposure

ACMA exclusion zone calculator
The ACMA exclusion zone calculator was developed by Dr Vitas Anderson and EMSS Consulting as an easy to use, accessible and reliable online tool to help small operators and amateurs assess compliance with the ACMA license condition determination (LCD) for Apparatus licenses for radio transmitters.

It provides dimensioned drawings, conservatively formulated, for RF safety exclusion zones based on the ACMA/ARPANSA E and H reference level limits for general public exposure (which in turn are derived from the ICNIRP 1998 limits).

It can be accessed at the ACMA website:

Dielectric and thermal properties of human tissues
Two spreadsheet tools have been developed by Dr Vitas Anderson and Dr Robert McIntosh for helping researchers to select appropriate dielectric and thermal tissue properties for numerical modelling of temperature rise due to RF exposures.

These tools have been released under the auspices of the Australian Centre for Bioeffects Research (now revived as the ACEBR).

The first tool calculates the dielectric properties (permittivity, conductivity, loss tangent, propagation constant, wavelength, etc) of human tissues according to Debye and Cole-Cole expressions developed by Hurt and Gabriel. It also provide a general calculator for dielectric material properties.

The second tool provides a database of recommended thermal tissue values (thermal conductivity, specific heat capacity, metabolic heat production, %water content, mass density, blood flow and heat sink strength) which were derived from an extensive literature review published in 2010 (R. L. McIntosh and V. Anderson, “A comprehensive tissue properties database provided for the thermal assessment of a human at rest,” Biophysical Reviews and Letters, vol. 5, pp. 129-151, 2010.)

Assessment guide for implants in RF workers
This document provides guidance on assessing whether persons bearing metallic implants inside their bodies should be restricted from exposure to the upper tier limits of the radiofrequency (RF) safety guidelines (1998) published by the International Commission for Non-ionising Radiation Protection (ICNIRP) and the C95.1 (2005) standard of the Institute of Electrical and Electronic Engineers (IEEE).

It was developed by Dr Vitas Anderson and Dr Robert McIntosh as a research project for the Asian Office of Aerospace Research and Development (AOARD) of the US Air Force Research Laboratories (AFRL), under the auspices of the Australian Centre for Bioeffects Research (now revived as the ACEBR).

An earlier edition of this document was published in the International EMF Dosimetry Handbook and its main recommendations have been incorporated into the ICES IEEE C95.1 2005 standard on safety levels with respect to human exposure to RF EMF.
