Americium-241 is a radioactive isotope that emits alpha particles. The rate constant for this radioactive decay is 1.47 x 10-3 per year. a. What is the half-life for the decay of americium-241? b. How long will it take for 45.0% of the americium to decay?
The half-life of radon-222 is 3.823 days. What is the rate (decay) constant of this isotope? (Report your answer in standard notation. Only include the number in the answer box.) k = ?????? day-1
The Cadmium isotope 109Cd is radioactive. A sample begins decay with 1012 Cd atoms. After 500 days, 4.7 x 1011 atoms remain. What is the half-life of this sample? (a) 46 days (b) 102 days (c) 459 days -- right answer but not sure how to get it (d) 662 days (e) none of the above
All radioactive decay processes follow first-order kinetics. The half-life of a gamma producing radioactive isotope is 2.4 hours. This isotope is used in a medical scan and enough of the isotope is given such that a heart scan can be done? If 0.75 ng of the isotope is administered, how ng of the isotope remains in the patient after 3.5 days?
14C is a radioactive isotope with a half life of 5.73x10^3 years. Radioactive decay is first order process and the amount of 14C present in an object can be used to determine its age. How long does it take for for 90 % of the 14C in a sample to decompose?
