Abstract
The natural background r-radiation was observed by 102.88 cc lithium drifted germanium detector. Twenty-five lines due to 228Ac were observed in the energy spectrum extending from 50 to 1, 280keV. Comparison with other workers led to identifying two unknown peaks and observing four new lines. A quantitative measurement of the peaks is given in terms of relative intensity of the observed γ-lines.
