Beta particles carry which type of charge?

Beta particles are a type of high-energy, high-speed electron or positron emitted during the radioactive decay of certain types of unstable nuclei. Specifically, beta particles can be classified into two types: beta-minus (β-) and beta-plus (β+). Beta-minus particles are electrons, which carry a negative charge. Therefore, when the question asks about the charge that beta particles carry, it is directly aligned with the nature of beta-minus particles since they are the most commonly referenced in the context of beta radiation.

In the case of beta-plus particles, also known as positrons, they carry a positive charge. However, because beta radiation typically refers to the emission of electrons as beta particles, the focus is primarily on the negative charge that these particles possess. As a result, stating that beta particles carry a negative charge accurately reflects their fundamental properties in radiation safety and physics.

Understanding this characteristic is crucial for those working in radiation safety, as different types of radiation pose varying risks and require distinct safety measures. In the context of industrial radiography, knowledge of the properties of beta particles is important for ensuring proper handling and shielding procedures.
