WebUseful for calculating today's activity for any radioactive isotope. You may also back decay sources to find out the original activity (or for any date), knowing the current activity. 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 ... WebThe weak gamma radiations from Co 57 were studied. In addition to the well known 14, 123, and 137 keV gamma rays, a 708 keV gamma ray was observed, having an intensity of 2 × 10 −3 gamma rays per disintegration. No annihilation radiation was observed; an upper limit of 5 × 10 −4 can be put on the number of positons per disintegration.

60 Co undergoes beta decay to the stable isotope nickel-60 (60 Ni). The activated nickel nucleus emits two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall equation of the nuclear reaction (activation and decay) is: 59 27 Co + n → 60 27 Co → 60 28 Ni + e − + ν e + gamma rays.
