✦ Synopsis

The intensities of some gamma-ray lines emitted from 234 Th and 234 Pa are usually used to estimate the concentrations of 238 U in different environmental samples. However, the absolute intensity values currently available for some gamma-ray lines which are used for determination of these concentrations seem to be inaccurate and include some discrepancies. In the present work, the absolute intensity values for some gamma-ray lines of 235 U, 234 Th and 234 Pa have been studied and precisely evaluated using a hyper pure germanium highresolution gamma spectrometer.
