ABSTRACT:
The present invention relates to a portable radiation measuring device, comprising a detector adapted to deliver electrical signals whose amplitude spectrum depends biunivocally on the energy spectrum of a radiation which may be received by the detector, amplification means and electronic means for compensating the sensitivity of the detector as a function of the energy so as to render it identical to that of human tissues, producing an output signal which is in a constant ratio with the energy of said radiation which may be absorbed by human tissues and display means, connected to the amplification and compensation means, for displaying the dose of radiation received by the detector.
