beta radiation consists of what type of sub-atomic particle?

Beta radiation consists of high-speed electrons or positrons, which are collectively called beta particles.

Quick Scoop

• In most school-level questions, the expected answer is: “electrons.”

• More precisely, beta radiation can be:
  • Beta minus (β⁻): streams of electrons emitted from unstable nuclei.

* **Beta plus (β⁺):** streams of positrons (the electron’s positively charged antimatter counterpart).

So, if the question is multiple choice or very short-answer, the safest concise response is:

Beta radiation consists of fast-moving electrons (and, more generally, electrons or positrons called beta particles).
