(a) Neutron activation of sodium, which is 100% 23Na, produces
24Na, which is used in some heart scans as seen in this table. The
equation for the reaction is 23Na + n → 24Na + 𝛾. Find its energy
output in MeV, given the mass of 24Na is 23.990962 u. (Assume 1 u =
931.5 MeV/c2.) MeV (b) What mass (in g) of 24Na produces the needed
6.5 mCi activity, given its half-life is 15.0 h?
