Interpretation Introduction
Interpretation:
The products of a fusion reaction are to be compared with the reactants.
Concept introduction:
Nuclear fusion is the process that involves the combination of two or more nucleus and results in the formation of a single product and emission of the neutron. The nucleus absorbs energy in this process.

As a result of measuring beta particles emitted from P-32 for 2 minutes with a GM counter(Geiger), it was 72,960 counts. If a P-32 standard source having the same shape as this source and having a radioactivity of 2 kBq was measured for 10 minutes under the same conditions as before and 320,000 counts were obtained, what is the radioactivity of the first P-32? (required for solution course)
