摘要: Abstract Half-lives have been obtained for a number of radionuclides by following the decay purified samples over periods time as long six years. The data were treated method least squares. half-lives are 284·5 ± 1·0 days Ce 144 71·3 0·2 Co 58 , 27·8 0·1 Cr 51 2·60 years Fe 55 278 5 Mn 54 2·66 0·02 Pm 147 366·6 0·9 Ru 106 and 84·1 0·3 Sc 46 .
