Cu64 half life
WebFeb 1, 2024 · combined physical decay and pharmacokinetic clearance is termed the effective half-life. The physical decay or half-life is the time required for a given quantity of radioactivity to decrease to one half of its original activity solely as a result of radioactive decay. For a radionuclide, ten physical half-lives will 5account for 99.999% of its ... WebDec 15, 2006 · In the 16th edition of the chart of nuclides, it lists Cu-64 as decaying to Zn-64 by beta minus decay. OK, no problem here. Then it lists Zn-64 decaying back to Cu-64 by positron decay with a half life of 1.1 x 10^19 years. Assuming this isn't some typo, I have 2 questions. 1) How in blazes did they manage to figure this half life out?!
