A person's body generates about 0.2 µCi of radioactivity! Determine the total radioactivity emitted by 300 students in a lecture hall. (1 Ci = 3.7 x 10¹⁰ Bq and 1 Bq = 1 decay/s)

Question

Quizplus · Accepted Answer

The total radioactivity is calculated by multiplying the radioactivity per person by the number of students: 0.2 µCi/person * 300 students = 60 µCi. Converting µCi to decays/s: 60 µCi = 60 x 10^-6 Ci = 60 x 10^-6 x 3.7 x 10^10 Bq = 2.22 x 10^6 decays/s, which is approximately 2 x 10^6 decays/s.
