What is the half-life?

The numerous synthesis and anti-synthesis processes create the paradigm for our universe. This natural phenomena project also has attributes of living organisms such as pairing, binary relationships, growth and finally decay. For the same reason, the ancient naturalist also defined biological substances as an artifact or living organisms similar to man.

In fact, in Chemistry, more precisely, it is Nuclear Chemistry in which the radioactive elements tend to decay and, after the process, are left with half their effective composition. The time it takes for these radioactive elements to disintegrate is called the half-life.

The half-life is a process that is highly uncertain and cannot be predicted for every situation. If you have been given two identical atoms, then there is a chance that one of them will decompose immediately while the other remains intact for a long period of time. As for the representation of the half-life, in practice, it is indicated by the eleventh alphabet of the Greek letters (λ). Worldwide, in terms of half-life, lambda (λ) is known as the radioactive decay constant.

After a certain time t, the number of unstable nuclei remaining after decay can be calculated through the formula,

      N (t) = N0 * 0.5 (t / T)

Where N0 is the initial quantity or number of atoms you start with and N (t) is the number of atoms remaining for a nuclide with half-life T.

There is also another formula for estimating the remaining value of a substance, which involves logarithmic functions.

N (t) = N (0) * e (-λt)

The exponential decay constant, i.e. lambda in the above formula can be calculated by this formula,

      λ = ln2 / T

Where is the half-life used?

A knowledge of the half-life is important because it allows the healthcare professional to determine how long it can store radioactive waste and isotopes before its disintegration. These radioactive isotopes are used to trace chemical or biological processes using devices that detect radiation. The other isotope of carbon-12, namely carbon-14, has proved very useful for nuclear scientists in calculating the most likely half-life of its substances. The process is known as carbon dating in which archaeologists and geologists use half-life methods to date primitive organic objects. Like carbon-14, after going through the alpha decay phase, it converts to nitrogen-14 and, upon complete demolition,

Different substances have different amounts of half-lives; it is almost impossible to evaluate or estimate a half-life of a substance by manually comparing it with another. For example, the carbon isotope, i.e. C-10, is unlikely to be considered because it has a half-life of only 19 seconds, making it impossible for other natural chemicals to interact with it and produce the resulting organic objects. Unlike carbon-10, uranium-233 has an approximate half-life of 160,000 years, making it one of the most vulnerable substances for high-energy fission reactions.
