Represents *The '''decay curve''' represents the rate of [[Decay (Physics)|decay]] of a [[radioactive]] substance.Shows *The '''decay curve''' shows the characteristic exponential [[Exponential Decay (Physics)|exponential decay]] pattern of [[radioactive]] materials.Used *The '''decay curve''' is used to determine the [[Half Life|half-life ]] of a [[radioactive]] substance.Helps *The '''decay curve''' helps in understanding the stability and longevity of isotopes[[isotope]]s.

𝑁(𝑡) is the number of undecayed [[Atomic Nucleus|nuclei]] at [[time]] (𝑡)

*The [[Decay (Physics)|decay]] curve of [[Uranium-238 ]] showing its decrease over millions of years.*Monitoring the [[Decay (Physics)|decay]] curve of medical isotopes to ensure they remain effective for treatment.
