| Popis: |
As part of an interlaboratory program, the half life of 240 Pu has been measured on a shared 240 Pu oxide material. Grown-in daughter 236 U was measured at four intervals in the range of 0.94–1.1 yr by isotope-dilution mass spectrometry. The measured half life is 6574 yr with 95% confidence limits of ±12.8 yr. Experimental uncertaities at all stages of measurement and their statistical treatment are discussed fully. |
