Interpretation Introduction

Interpretation:

The type of the radiation should be identified.

Concept introduction:

Radiation is the emission of energy in the form of waves or particles through space or through a material medium.

Alpha radiation: it is one of the radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.

Beta radiation: it is a symbol of $\text{β}$ is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay

1. (i) $\text{β-}$ decay another
2. (ii) $\text{β+}$ decay, which produce positrons and electrons respectively.

Positron emission: $\text{β+}$ decay is called positrons emission

Fission: one particle split into two or more parts is called fission.
