7.2 What is Half Life?

7.2 What is Half Life?. Half Life is the time required for half of the radioactive sample to decay. Half-life. Half-life is constant for any radioisotope and can be used to measure the rate of radioactive decay for that isotope. Strontium-90 has a half-life of 29 years.

7.2 Half Life

7.2 Half Life. A half life can be used to compare the rate of radioactive decay for an isotope. The shorter the half-life, the faster the decay rate. All radioactive decay rates follow a similar pattern called a decay curve.
