As a result of being exposed to the radiation released
Chapter 20, Problem 86AP(choose chapter or problem)
As a result of being exposed to the radiation released during the Chernobyl nuclear accident, the dose of iodine-131 in a person's body is \(7.4 \mathrm{mC}\) \(\left(1 \mathrm{mC}=1 \times 10^{-3} \mathrm{Ci}\right)\) Use the relationship rate \(=\lambda N\) to calculate the number of atoms of iodine-131 to which this radioactivity corresponds. (The half-life of \({ }^{131} \mathrm{I}\) is 8.1 days.)
