Beta Particle

A beta particle is one of the elementary particles that is emitted by the nucleus of a radioactive atom during beta decay. It is either an electron (negative charge) or a positron (positive charge).

When a radioactive atom is in an unstable state, it can emit a beta particle to reach a more stable state. This occurs by losing or adding electrons to the nucleus of an atom.

A beta particle has high energy and a very small size, making it very light and fast. Its mass is approximately 0.51 MeV/c², which is 1836 times less than the mass of an electron.

Beta particle studies are an important tool for studying the properties of radioactive isotopes and their interactions with the environment. They are also used in medicine to diagnose and treat cancer.

However, beta particles can be hazardous to human health, as they can cause radiation exposure and cell damage. Therefore, when working with radioactive materials, it is necessary to take precautions and use protective equipment.
