Question 6. At Canadian Light Source, a synthetie radioisotope is freshly prepared. The initial activity of the radioisotope is 10.0 mCi, and the activity changes to 0.08 Ci in 25.0 hours. (a) What is the decay constant and half-life of the synthetie radioisotope sample in se- onds?. (b) What is the sample's activity in u Ci 50.0 hours after it is prepared? (c) After how many half-lives, will a 2.00% of this synthetic sample remain?
