Radiation detector for measuring one or more characteristics of a radiation, comprising one or more detector pixels, a clock pulse generator, each detector pixel comprising a sensor producing an electrical signal in response to an event of a photon or charged particle of said radiation impinging on said sensor; a pixel electronics adapted for receiving and processing said electrical signal, comprising an analog processing unit for amplifying and shaping said electrical signal and producing a shaped pulse said pixel electronics comprises time determination unit for counting the TOT-count, the TOT-count being the number of clock pulses occurring during the time interval when said shaped pulse is above a threshold. Said pixel electronics comprises a plurality of event counters, each event counter counting the number of events having a TOT-count in a predefined ranges.

Radiation monitoring device

A radiation sensing device subdivided in N*M pixels, comprising: a conversion part to convert an impinging radiation into an electrical signal, a processing part having: for each pixel, at least two counters associated to different regions, so that a ratio of counters to pixels is at least equal to 2, an arbitration circuit which, for each pixel: receives detection information from the pixel and neighbouring pixels, taking into account detection information for the pixel and neighbouring pixels, allocates a detection value to an elected counter.
