摘要：

A method of measurement and analysis of gamma spectra of short living fission products of lightly irradiated fuel pins has been developed at facilities at the LR-0 zero-power experimental reactor. Experimental and computational methods of the peak area correction for radioactive decay are described. Selection of energy peaks suitable for deriving power distribution in the core was performed.
