  • The NCRP has long mcog&ed the need for a clear assessment of the magnitude of doses from various souroes of radiation to which the population of the U.S. is ocpo9ed. In anticipation of the need to gather data for input into this process five as&sament committees, each adhing a different source category, wem established, first in 1971 and then reestablished in 1986. NCRP reports assessing exposum from natural background, consumer products, and nuclear power gene ation have recently been published (NCRP, 1987% 1987b. 1987~)...

  • This book is intended as an introductory text for Engineering and Applied Science Students to the Medical Applications of Electronics. A course has been offered for many years in Cardiff in this arena both in this College and its predecessor institution. A new group, the Medical Systems Engineering Research Unit, was established following the reorganisation of the College. Restructuring and review of our course material and placing the responsibility for teaching this course within the new group led to a search for new material.

  • The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasingly technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for nuclear medicine.

  • The National Council on Radiation Protection and Measurements (NCRP) published Report No. 48, Radiation Protection for Medical and Allied Health Personnel in 1976. Many changes in medical practice and procedures involving ionizing radiation have occurred in the intervening 13 years. As a result, the Council determined to prepare this new report to supersede NCRP Report No. 48. The primary objective of this new report is to update the material to include new radiation sources used in medicine.

  • The promoter of the early growth response gene (Egr-1) has been described to be activated by ionizing radiation, and it seems to be clear that this process involves di€erent mitogen activated protein (MAP) kinases, dependent on the speci®c cell type examined. However, early steps leading to activation of the corresponding pathways and thus to overexpression of Egr-1 are not well understood.

  • I like playing around with words and letters. You probably know that LASER is an artificial word derived from “Light Amplification by Stimulated Emission of Radiation”. When starting my lecture on “Laser–Tissue Interactions” I tend to write this derivation on the board. I continue with “LIGHT: Lasers Irradiate Germinated and Healthy Tissues”. Why? Lasers cut everything, if appropriate laser parameters are selected. There is no shield around healthy tissue. And there is no laser that fits all sizes as some clothes do. Lasers never have been some kind of wonder instruments.
