| Abstract | The development of primary standards of absorbed dose for electron beams has lagged somewhat the development of photon beam standards. However, this has not limited the diversity of designs, or the range of applications. This review describes the state-of-the-art in electron beam standards as practised today in a number of primary standards laboratories and research institutions around the world. The devices detailed cover electron energies from 80 keV to 25MeV and doses from 1Gy to tens of kilogray, although the focus of the majority of research is on dosimetry for radiation therapy. |
