METHOD OF DETECTING NUCLEAR EXPLOSITION FROM KRYPTON AND XENON ISOTOPES Russian patent published in 2010 - IPC G01T1/167 G01T1/30 

FIELD: physics.

SUBSTANCE: components of different types of fissions in the overall activity of krypton and xenon isotopes is determined by generating a signal F₁ for the given moment of separation t_q and measurement time t, obtaining a system of linear algebraic equations at fixed values for each iteration from the signal F₁ by differentiating said system on elements pN_j, solving the system of linear algebraic equations by forming several target functions and using 4 methods for multi-criteria mathematical programming by reducing the multi-criteria problem to a single-criterion problem with limitations, using iterative calculation procedures to solve the said single-criterion problem with limitations for given t_q with estimates of elements of a two-dimensional signal specified on each iteration, determination of point signals of components of types of fissions into the overall activity of isotopes. To determine the moment of separation t_q, components pN_j are calculated at equal t_q and t_q for which the relationship is minimal is selected.

EFFECT: high efficiency of determination and accuracy of point estimates of components of different types of fissions into the overall activity for each krypton and xenon isotope.
