Question

True or false? 10 g of a radioactive isotope has an activity of 15 bq. Therefore it can be predicted that 20 g of the same isotope will have an activity of 30 bq.

Answer 1

True

Step-by-step explanation:

The activity of a radioactive sample is directly proportional to the amount (mass) of the sample. Therefore, if the activity of 10 g of a radioactive isotope is 15 bq, then the activity of 20 g of the same isotope will be twice as much, or 30 bq. This assumes that the decay properties of the isotope remain constant with increasing mass.
