Answer :
Half life, as stated, is a measurement of the rate at which radioactive material decays.
What is radioactive, and what kinds are there?
This process can be artificially produced by people, such as within a nuclear reactor, but can also occur spontaneously in nature. Depending on the particles or energy generated during the reaction, there are many kinds of radioactivity. Alpha particles, beta particles, and gamma rays are the three categories.
Briefing:
Average and half-life are two characteristics that may be used to describe the decay constant. Moments are used as the measuring unit in both scenarios. The average lifespan of such an element, as indicated by its name, may be expressed in the form of the following affirmation:
Nt=N₀ * e^(−λt).
The duration of time that is defined by how long it takes for half of a material to degrade is known as its half-life (both radioactive and non-radioactive elements). All through process of decay, its rate of decay is constant. It may be seen by:
Nt=N₀* (1/2)^(t/t₁₂).
