The Nature of Radioactivity

A fundamental understanding of radioactivity is crucial in comprehending the potential risks associated with radioactive building materials. Radioactivity is a natural phenomenon in which unstable atomic nuclei lose energy by emitting ionizing radiation, which can take the form of particles or electromagnetic waves.

What is Radioactivity?

With radioactivity, atoms undergo spontaneous disintegration, transforming into different atoms and emitting energy in the process. This emission of energy is what we refer to as radiation, and the materials that exhibit this phenomenon are said to be radioactive.

Radioactivity is measured in units known as becquerels (Bq), which quantify the rate of radioactive decay in a sample. Understanding the nature of radioactivity involves recognizing the three primary types of radiation: alpha, beta, and gamma.

The Different Types of Radiation

Alpha radiation consists of positively charged alpha particles, which are relatively large and can be stopped by a sheet of paper or human skin. Beta radiation involves fast-moving electrons or positrons that can penetrate deeper into materials, such as wood or plastic.

Gamma radiation is high-energy electromagnetic radiation that can penetrate most materials, making it the most difficult to shield against. Neutron radiation, although less common, can also pose risks due to its ability to interact with nuclei and induce transmutation.
