Describe beta radiation as a high-speed electron emitted from the nucleus.

Within Radioactive decay and nuclear radiation, this learning objective asks you to describe beta radiation as a high-speed electron emitted from the nucleus. Focus on the approved ideas beta radiation and connect them clearly to Atoms and nuclear radiation. A strong response should state the relevant particle, radiation, isotope, decay, half-life or nuclear-equation idea, then explain how it answers the exact command word. Avoid swapping nearby concepts such as atomic number and mass number, isotope and ion, alpha, beta and gamma radiation, or contamination and irradiation.
