| 摘要 |
The present invention relates to a process and installation for simultaneously measuring the flux of ionizing radiation, of an energy greater than several kVe and the dose of radiation received by a body exposed to this radiation. Process characterized in that it consists, first of all, in subjecting a semiconductor detector (2) operating in impulsional mode to the radiation to be applied to said body (1), in recording a first energy spectrum of the instant radiation at said detector (2), then in emplacing said body (1) between the radiation source (3) and the detector (2), in then subjecting said body (1) to said radiation for the predetermined duration and recording a second energy spectrum of the radiation incident at said detector (2), in computing a differential energy spectrum from said first and second spectra and segmenting it at energy intervals, and, finally, determining, on the one hand, the total radiation dose absorbed by the body (1) by summation of the elemental doses calculated for each of the mentioned intervals of said differential spectrum and, on the other hand, the flux emitted from the first spectrum of recorded energy.
