Beta particles can be a health hazard either as internal or external radiation due to ionization in tissues. Is this statement true or false?

The statement is true. Beta particles are a type of ionizing radiation emitted during radioactive decay, and their ability to interact with matter, including biological tissues, makes them a potential health hazard.

When exposed externally, beta particles can penetrate the skin, leading to ionization of cells and tissues. This can cause damage to cellular structures, potentially resulting in radiation burns or increasing the risk of cancer over time.

Internally, beta particles can be particularly hazardous when radioactive materials emitting beta radiation are ingested or inhaled. Once inside the body, they can directly ionize atoms in biological molecules, leading to cellular damage and disruptions in metabolic functions.

The risk associated with beta particles is recognized in radiation safety protocols, emphasizing the need for protective measures when working with or around radioactive materials.
