A 5.0 mL sample of cobalt-60 used in cancer therapy contains 2.00 mCi. How many becquerels are present? (Hint: notice that you have 2 milliCuries not Curies)
Homework Answers
conversion to be used:
1 Ci = 3.7*10^10 Bq
we have:
2.00 mCi = 2.00*10^-3 Ci
= 2.00*10^-3 * 3.7*10^10 Bq
= 7.40*10^7 Bq
Answer: 7.40*10^7 Bq

1. Cobalt 60 is commonly used as a source in industrial radiography (nondestructive testing of steel products by imaging with gamma radiation). A typical Co source is 100 Curies. Given a half-life of 5.27 years: (a) Calculate the mass of Co needed for a 100 Ci source (Atomic mass = 59.9338 g/mole). (b) If the source is abandoned in a warehouse for 22 years, how many half-lives have elapsed? (c) How much activity remains?
