ICRU Report 21 treated the basic aspects of electron-beam dosimetry with special attention to the use of electron beams in radiation therapy. Since that report was completed, the use of high-energy electrons in radiation therapy has expanded and linear accelerators and microtrons have come into more frequent use beside the previously dominating betatrons. The properties of the clinical electron beams in present use are, therefore, greatly diversified and new characterizations are needed to describe the beam qualities for dosimetric and therapeutic use. This report explains how absorbed dose can be determined for electrons with initial energies between 1 and 50 MeV, a range chosen to include beams which are produced by linear and circular accelerators used in medicine, radiation chemistry and radiation biology. This report is primarily concerned with quantities and methods which are sufficiently well established to be useful in standardization. However, in some important areas in clinical electron-beam dosimetry such methods do not exist. An attempt has been made to analyze these situations and suggest some quantities and methods which may fill the gaps.
