Which type of radiation emits particles of helium nuclei?
alpha radiation
beta radiation
induced radiation
gamma radiation
I think a or d
i think you're right
hint : gamma is electromagnetic (not particle)
You are correct. The type of radiation that emits particles of helium nuclei is alpha radiation, which is represented by the symbol α. It consists of two protons and two neutrons, making it identical to a helium nucleus. When an unstable atom undergoes alpha decay, it emits an alpha particle in the form of helium nuclei.
To reach this conclusion, it is essential to be familiar with the basics of nuclear decay. Radioactive decay occurs when an unstable atomic nucleus loses energy by emitting radiation. There are several types of radiation, including alpha, beta, and gamma radiation.
Alpha radiation, as mentioned earlier, emits alpha particles—helium nuclei. Beta radiation, on the other hand, consists of high-energy electrons (beta particles) or positrons (positron emission). Induced radiation refers to the process of inducing radioactivity in a substance through various means, such as exposing it to a source of radiation. Gamma radiation, the final option you mentioned, consists of high-frequency electromagnetic waves and does not emit particles.
In summary, the correct answer is option a, alpha radiation.
