METHOD OF OBTAINING THORIUM-228 RADIONUCLIDE Russian patent published in 2013 - IPC G21G1/08 

FIELD: physics.

SUBSTANCE: in the disclosed method of obtaining a ²²⁸Th radionuclide, which involves irradiating a target, the target material is a natural thorium isotope - ²³⁰Th, the target is placed in a linear electron accelerator and irradiated with γ-quanta of deceleration radiation, and the desired ²²⁸Th radionuclide accumulates therein during the threshold nuclear reaction ²³⁰Th(γ,2n)²²⁸Th. The target material can be ²³⁰ThF₄ or ²³⁰ThO₂ or ²³⁰Th metal.

EFFECT: obtaining α-radiating nuclides, which enables to eliminate shortage of therapeutic α-radiators on the market of medical radionuclides and satisfy increasing demand in the future.
