Characteristics of α-radiation, β-radiation and γ-radiation
A) α-radiation The α-rays are not rays, but consist of a stream of positively charged particles, having 2 units of positive (+) charge, and 4 units of mass. Thus, α-particles are doubly ionized helium atoms i.e., He2+. The α-particles emitted by any radioactive source are shot out with high velocity. The initial velocity depends on … Read more
