Strontium-90 decay diagram The strontium-90 decay diagram displays two main features. First, it happens to be a cascade decay. Strontium-90 decays into unstable Ytrium-90 that later decays into stable zirconium-90. The Ytrium lifetime is much shorter than that of Strontium-90 (respectively 64 hours and 29-years radioactive half-lives).

Na 22 decay

If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to perform the calculation. • Drying can form airborne Na-22 dust contamination. Rapid boiling can cause airborne Na-22 contamination. • Expelling Na-22 solutions through syringe needles and pipette tips can generate airborne aerosols. • Use high-density (high Z) shielding material to shield Na-22 (lead). • Use remote handling tools when handling > 1 mCi of Na-22. 2011-05-04 Na-22.

1 Decay Scheme Am-241 decays 100% by alpha transitions to Np-237. Most of the decay (84.6 %) populate the excited level of Np-237 with energy of 59.54 keV. Branching of Am-241 decay by spontaneous ﬁssion is 3,6 (9) E-10 %. L’am´ericium 241 se d´esint`egre a 100 % par ´emission alpha vers le neptunium 237. Le branchement principal

Data accumulated from 1980 to 1987 by the gamma-ray spectrometer aboard the SMM are analyzed to search for annual increases at 1.275 MeV as evidence of Na-22 decay in the Galactic center region
