Question:
Sodium-23 (in a sample of NaCl) is subjected to neutron bombardment in a nuclear reactor to produce 24Na. When removed from the reactor, the sample is radioactive, with β activity of 2.54 × 104 dpm. The decrease in radioactivity over time was studied, producing the following data:
(a) Write equations for the neutron capture reaction and for the reaction in which the product of this reaction decays by β emission.
(b) Determine the half-life of sodium-24.
