METHOD OF MEASURING RADIATION INTENSITY Russian patent published in 2014 - IPC G01T3/06 

FIELD: physics.

SUBSTANCE: radiation intensity of a source is measured by measuring spatial distribution of a full signal I_f(x) along the direction of propagation of primary radiation, normalising, via a least-square method, the measured and theoretical distribution until values thereof match at the initial section, determining spatial distribution of the background signal from the equation: I_fon(x)=I_f(x)-I_theor(x), and determining spatial distribution of the useful signal as the difference between distribution of the full signal and the background signal, where: I_theor(x)=A·exp[-µ(E)·x] is the theoretical distribution of the useful signal along the direction of propagation of primary radiation, I_f(x) is the spatial distribution of the full signal, µ(E) is a coefficient of linear attenuation of primary radiation in the scintillator material, x is the direction of primary radiation, E is the energy of primary radiation.

EFFECT: measuring the input of background radiation in the signal of the detector, high measurement accuracy, enabling measurement in difficult radiation conditions, reducing limitations on dimensions of the detecting element.
