A 10 Curie source of Co-60 is discovered in an unused vault. A label on the source indicates the source was created March 1, 1942. What is the activity of the source today in uCi?(2 pts) Na-24 is produced during neutron irradiation of a product. The product is not safe to handle until 4 half-lives have elapsed and the activity has decayed to 2 µCi. What is the initial activity in this scenario?
