چکیده انگلیسی
This paper deals with the use of diamond detectors operating in the current mode, i.e. in particularly high-intensivity fields of X- and γ-rays. It is concerned with the monitoring of broad photon energy spectra close to radiation plans. The discussions are supported by numerical response simulations of diamond detectors foreseen to control real-time absorbed or ambient dose rates. The collected charges and the current delivered by the irradiated detectors are analysed to propose stacks of materials with less than 30% measurement uncertainty in an unknown 20 keV-1.5 MeV photon (X- or γ-rays) field. Single-sensor monitors show sensitivities sufficient for X-ray manipulation alarm dosimetry.
