k = 0.693/t1/2
k will be in yr^-1.
Convert 310 mg Co to g, then to moles. moles = grams/atomic mass.
moles x 6.02E23 = # atoms.
Rate = # atoms x k(from above) = decays per year.
Convert that to 190 sec.
Convert that to decays per sec (dps) and that will be # Bq.
Write a nuclear equation for the following: Iodine 131 undergoes beta decay two times Plutonium 239 is an alpha emitter Th 234 undergoes beta decay once and then alpha decay How do I go about writing nuclear equations?
When U238 decays into Pb206 via alpha and beta decay, what are the byproducts of the decay? A) 8 alpha particles and 6 beta rays. B) 8 alpha particles, 6 electrons, 6 neutrinos, and energy. MY ANSWER . C) 16 alpha particles, 16
which of the following choices correctly describes the decreasing ability of the radiation to penetrate a sheet of lead that is 3 inches thick? A. alpha particles > beta particles > gamm rays B. gamma rays > alpha particles > beta

So we did this lab about how we are to measure the half life of the beta decay of indium 116 (the indium 116 is captured by indium 115 and undergoes beta decay to become tin 116. Since the Indium 116 I reused I understand that
