What is half life? It is a term that describes the duration of a substance’s breakdown or transition until it is reduced to half of its initial amount. This concept is most commonly employed to refer to the decay of atoms in the fields of chemistry and physics. However, it can also be useful to represent other types of decay.

The primary half life formula is:

Nt is the quantity of substance remaining after time t.

N0 is the initial quantity of the substance.

t is the elapsed time.

t1/2 is the half-life of substance.

This half life equation allows scientists to anticipate how much of a material will remain at any given time. But in addition to the aforementioned half life formula, the following two equations can also be used to describe exponential decay:

In the above equations,

τ is the mean lifetime.

λ is the decay constant.

To further understand the concept of half life equations, let’s consider some real-life data and enter them into any of the above-specified half life formulae:

Assume that 800 mg of radioactive material decreased to 50 mg in 20 minutes. What will be the half-life of this nuclide in such a situation?

Initial quantity of the substance (N0) = 800mg

Elapsed time (t) = 20 minutes

Quantity of substance remaining after time t (Nt) = 50mg

Since we want to determine the half-life (t12) of a substance here, it is essential to rearrange the main formula for t12. After rearrangement, the formula will become,

t ½ =

2log ^{2}

(log^{0}/Nt)

t ½ = 5 minutus

What would be the period of death of a fossil sample if an archaeologist discovered that it contained 25% more Carbon-14 than a live sample?

In order to calculate the time (t) of the fossil’s sample death, let’s modify the main formula for t. After rearrangement, the formula will become,

Half-life (t12) of Carbon-14 is approximately 5,730 years

Quantity of substance remaining (Nt) = 25%

Hint: The general rule of thumb is to represent the remaining percentage as a fraction. Therefore, the initial quantity of the substance (N0) will be 100.

By inputting the values, the formula for t will become,

t =

5730In($\frac{25}{100}$)

-lnln2

t=11460 years old

Half-life has become an invaluable resource for scientists belonging to various scientific disciplines. Here are a few types that showcase the versatility of the half life concept:

Radioactive decay represents the duration required for a radioactive material to decay to half of its initial amount.

Biological half life describes how long it takes for a drug or treatment to be eliminated by the body or decreased to half its concentration in the circulation due to excretion and metabolism.

Chemical half life shows how long it takes for a chemical compound’s concentration to drop to half of its starting value due to interactions with external circumstances or other substances.

The population dynamics half life describes how long it takes for a population to decrease to half its starting size due to factors like habitat loss, illness, or predation.
