Atypical amount of 99mtc injected for medical imaging is 15.0mci. convert this to decays per second, also called becquerels (bq, the si unit of activity.\

Bq

Explanation:

Radioactivity is the phenomenon in which a less stable nuclei decomposes to a stable nuclei by releasing some radiations or particles like alpha, beta particles or gamma-radiations.

Radioactivity is measured in units of curie (Ci) or becqerels (bq).

1 millicurie = Curie

Thus 15 millicurie = Curie

1 Curie is equal to Bq

0.015 Curie = Bq

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots
