Convert the standard radioactive activity unit into its equivalent value in Rutherfords (rd).Nuclear Chemistry and Radioactivity Chemistry Question

Question

Convert the standard radioactive activity unit $1\text{ millicurie (mCi)}$ into its equivalent value in Rutherfords (rd).

Answer: B

💡 Solution & Explanation

$1\text{ Curie (Ci)} = 3.7 \times 10^{10}\text{ dps}$. $1\text{ millicurie (mCi)} = 3.7 \times 10^7\text{ dps}$. $1\text{ Rutherford (rd)} = 10^6\text{ dps}$. Therefore, $1\text{ mCi} = (3.7 \times 10^7) / 10^6 = 37\text{ rd}$.
