摘要：

The high sensitivity and the nearly tissue equivalence of diamond make it a material suitable as detector for on-line dosimetry. The tremendous development of the CVD diamond technology allows to employ polycrystalline diamond films with controlled dimensions and a potential low cost as on-line radiation dosimeters. In this paper a characterisation and a comparison of the response of two "detector-grade" CVD diamond films under photon and electron beams are presented. The results show that both samples can be used as on-line dosimeters for applications in radiotherapy. (C) 2000 Elsevier Science B.V. All rights reserved.
