Which of the following relationships concerning the units of radioactivity are mathematically correc — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

All options are correct. $1\text{ Bq}$ is defined as $1\text{ dps}$. $1\text{ Curie (Ci)} = 3.7 \times 10^{10}\text{ dps} = 3.7 \times 10^{10}\text{ Bq}$. $1\text{ Rutherford (rd)} = 10^6\text{ dps}$. $1\text{ mCi} = 3.7 \times 10^7\text{ dps}$. To convert this to Rutherfords, divide by $10^6$, giving $37\text{ rd}$.
