Instrument for X and gamma-radiation parameter measurement

An instrument for measuring X or gamma-radiation parameters, which contains a set of converters, installed in an opaque vessel and located in sequence is described. The converters are separated by a scintillator. Energy dependense of the scyntillator efficiency is mirror opposite to energy dependence of the converters efficiency. The invention is aimed at the increase in accuracy of dose rate measurement and in calibration flexibility. It is achieved by the additional introduction of correction of total energy dependence of each pair of edge and middle converters efficiency. The invention can be used to acquire information on the dose rate and effective wavelength of X radiation. It can also be used in the system of X-ray device control. The use of the invention ensures an increase in the accuracy of dose rate measurement with calibration flexibility
