ISOTOPE METHOD FOR SEPARATING THALLIUM Russian patent published in 2007 - IPC B01D59/00 B01D59/50 C01G15/00 

FIELD: medicine.

SUBSTANCE: method is divided into stages and involves producing photons of the first frequency corresponding to wavelength of 378 nm; photons of the second frequency corresponding to wavelength of 292 nm; photons of the third frequency corresponding to wavelength from 700 to 1400 nm. Photons of the first frequency are produced with one or more continuous radiation laser. Photons of the second and third frequency are produced with one or more pulsating radiation laser. The first, second and third frequency photons are applied to atomic vapor containing several Thallium isotopes. Photons of the first frequency pump Thallium isotope assembly in base state and transfer them to metastable state with energy level of 7793 cm^-1 over the first excited state distinguished by energy level of 26477.6 cm^-1 relative to zero energy of the basic state.

EFFECT: high reliability of diagnosis.
