1) Define what is meant by the half - radioactive material.
2) Radioactive decay is a random process. Explain what this means.
3) The activity of radioactive sample is measured. The activity corrected for background radiation is found to be 240 Bq. The activity is measured again after 1 hour 30 minutes and is now 30 Bq. What is the half life of the sample?
