Title:
LINEARIZATION METHOD FOR MASS ABSORPTION CURVE OBTAINED THROUGH ATTENUATION OF RADIATION
Document Type and Number:
Japanese Patent JPS5892826
Kind Code:
A
Abstract:
The invention relates to a method which can be used, in particular, in radiometric weighing devices and for the radiometric determination of density. Whereas the aim of the invention consists in reducing the expenditure and in the improved use of the radiator activity, it is the object of the invention to use digital computing technology to linearise the attenuation curves over the entire range of the intensity of radiation. According to the invention, all the pulses which leave a specific detector in a selectable time unit are counted and the pulse numbers are assigned specific mass elements or pseudo-masses. The mass elements and pseudo-masses are corrected in a fine linearisation and supplemented to form a linear dependence of the attenuation of the nuclear radiation on the transirradiated mass.
