Plutonium-239 has a half-life of 24,120 years. Assuming we started with 20 grams, how much plutonium would there still be after 30 years
Added by Kelli E.
Step 1
First, we need to find out how many half-lives have passed in 30 years. To do this, we can divide the total time (30 years) by the half-life (24,120 years): Number of half-lives = 30 years / 24,120 years = 0.001243 Show more…

Plutonium-239 decays as in the previous problem with a half-life of 24000 years. How much of an original quantity of plutonium will still exist 72000 years after it was produced in a reactor?
An isotope of plutonium has a half-life of 3.75 years. If you begin with 87 grams of plutonium, how much will remain after 6.0 years

The half-life of the radioactive element plutonium-239 is 25,000 years. If 16 grams of plutonium-239 are initially present, how many grams are present after 25,000 years? 50,000 years? 75,000 years? 100,000 years? 125,000 years?
