Textbook Problem

Chromium’s radioactive isotope 31Cr has a half-life of 27.7 days and is often used in nuclear medicine as a diagnostic tracer in blood studies. Suppose a 51Cr sample has an activity of 2.00 μCi when it is placed on a storage shelf. (a) How many 51Cr nuclei does the sample contain? (b) Calculate the sample’s activity in Bq when it is removed from storage one year later.
