Isotopic uranium determination in urine by alpha spectrometry is the current method to monitoring the contribution of U, U and U. Alpha spectrometry data of samples from. An analysis has been elaborated to determine the long-living γ-emitting fission products of uranium.

It consists of a sodium bisulphate melt of the fission product solution or the U-fuel, followed by liquid-liquid extractions.

Afterwards the isotopes are absolutely counted with a standardized 3″×3″ NaI crystal. The total γ-spectrum of the original fission product solution, taken with a.nuclear weapon tests [1].

Radiochemical determination of plutonium isotopes in environmental samples can be done by alpha spectrometry [6–8].
