Beta-spectra identification in gamma-emission indicating radiometric control

For analysis of /spl beta/-emitters an isotope composition was selected from salt sedimentation samples on the walls of a uranium-graphite reactor primary circuit. Spectrum measurements were carried out 10 days after reactor shutdown. A differential stream of /spl beta/-radiation from a unit sample surface was calculated. The differential stream is a degraded spectrum of salt sedimentation /spl beta/-radiation. /spl beta/ and /spl gamma/-ray doses are presented.
