Yes, nuclear radiation is radiation emitted from the nucleus, and there are three types of nuclear radiation: alpha particles, beta particles, and gamma rays. Radioactivity is a broader term that is used to describe the emission of radiation from any source, including the nucleus. Radioactivity can come from other sources besides the nucleus, such as cosmic rays. Not all radiation is nuclear radiation; there is also non-nuclear radiation, such as microwaves, x-rays, and infrared radiation.
