Key Concepts

Radioactive Decay

Radioactive decay is the process by which unstable nuclei lose energy by emitting radiation. It is characterized by a spontaneous transformation that follows statistical rules, leading to a predictable decrease in the number of radioactive atoms over time.

Half-Life

The half-life of a radioactive substance is the time required for half of the nuclei in a sample to decay. It is a key parameter in understanding decay processes and allows for the determination of remaining quantities of a radioactive material after a given period.

Exponential Decay

Exponential decay describes the mathematical model of how the quantity of a decaying substance decreases over time. In this model, the amount of a substance remaining decreases by the same proportion during each equal time interval, corresponding directly to the concept of half-life.
