摘要：
CVD diamond detectors have been evaluated for use as X-ray dosimeters. The response both at radiological diagnostic and at therapeutic energies of one "detector grade" commercially available parallelepiped CVD sample has been measured and compared with the performances of a "needle shaped" CVD diamond detector grown by the hot-filament CVD technique on a tungsten tip. All the detectors were demonstrated to be very suitable for bio-medical application: they are linear in dose rate, stable and relatively fast, with a signal-to-noise ratio higher than 1000.
