An assembly () for monitoring ionising radiation comprises a detector substrate () for generating electronic charge responsive to incident ionising radiation, the detector substrate () having an array of ionising radiation sense volumes () formed in it. A circuit substrate () supporting an array of read-out circuits () corresponding to the array of sense volumes is mechanically and electrically coupled to the detector substrate (). Each of the read-out circuits () is switchable between first and second charge integration modes for receiving charge from a corresponding sense volume. A charge integration circuit () is configured in the first charge integration mode to integrate charge corresponding to sensing of a single ionising radiation detection event in a corresponding sense volume and in the second charge integrating mode to integrate charge corresponding to sensing a plurality of ionising radiation detection events in the corresponding sense volume.
