In this lesson, we will learn how to calculate the activity of a radioactive sample after a given amount of time using the sample’s half-life.
Students will be able to
Q1:
The initial activity of a sample of radioactive material is 800 Bq. What is the activity of the sample after 3 half-lives have passed?
Q2:
What is the activity of a radioactive sample after six half-lives have passed, as a fraction of its initial activity?
Q3:
The initial activity of a sample of radioactive material is 1,200 Bq. What is the activity of the sample after 1 half-life has passed?
