Natural radioactivity consists of emission - JAMB Physics 2020 Question
Natural radioactivity consists of emission___
A
\(\alpha\)-particles and \(\beta\)-rays
B
\(\alpha\)-particles and X-rays
C
\(\gamma\)-ray and X-rays
D
\(\alpha\)-particles and \(\beta\)-rays and \(\gamma\)-rays
correct option: d
Radioactivity is the spontaneous emission of radiation from atomic nuclei. This radiation can consist of alpha, beta, and gamma radiation.
Natural radioactivity is a purely nuclear phenomenon. The nucleus of a radioactive substance is unstable and such an unstable nucleus undergoes spontaneous breakdown (disintegration). The process continues until a stable nucleus is obtained.
