Radiation Quantities: Significance of the Angular and Energy Distribution of the Radiation Field
This paper discusses the effects of changing from the old to new (ICRP 60 and ICRU 47) dosimetric quantities, and the relationship between quantities, as a function of the energy and angular distribution, for practical radiation fields. It considers: X rays, gamma rays, neutrons and beta rays; reviews the limited data on practical energy and angular distributions for photons and neutrons in the workplace; and calculates relevant dosimetric quantities based on realistic assumptions. The results are used to illustrate how the relationship between quantities might vary in practical fields and to draw conclusions about the implications of recent ICRP and ICRU publications.
