The International Commission on Non-Ionizing Radiation Protection has commenced the revision of its EMF guidelines in the frequency range up to 300 GHz. The ICNIRP International EMF Dosimetry Workshop has brought together a range of scientists to discuss the basis of the existing guidelines and to highlight those areas where attention needs to be given. This report is an attempt to extract the key messages from each of the presentations. A tabulation of the important issues discussed in the summary and conclusion session is provided at the end of this report.
