Half-life of a radioisotope is?
The half-life of a radioisotope is the time it takes for half of the atoms in a sample to undergo radioactive decay. It is a fixed characteristic of each radioisotope and can vary widely, from fractions of a second to billions of years. The concept of half-life is crucial in understanding the rate of radioactive decay and in numerous applications in science and technology.
What is radioisotope in a sentence?
A radioisotope is an unstable form of an element that emits radiation as it decays.
How many half-lives have passed?
To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.

How many half lifes with in plutonium?
Plutonium-239, a common isotope of plutonium, has a half-life of about 24,100 years. To calculate the number of half-lives, divide the total time by the half-life. For example, in 48,200 years, there would be 2 half-lives.
