As from redioactive material alpha beta gamma rays are emitted, here alpha and beta particle holds +ve, -ve charge respectively same case with gamma rays these are neutral as neutron having no charge. what are the dissmilarities between both??

Neutrons can also be emitted like spontaneous fission of heavy element. Cf 252 emits fission neutron. Answer should be All

Neutron reside in the nucleus of the atom and it is heavy than other elementary particles hence it is imposssible to have a emission of neutron.

Radioactivity is the spontaneous emission of energy from unstable atoms.

Option D correct.
If neutrons are emitting in a spontaneos fission process, that is not radioactive process. And as far radoiactive particales are three, alpa, beta, gamma. Neutrons not including this.

Here answer should be B because electromagnetic radiations are simply light waves that have velocity as c.

Neutrons are not emitted by the radio active substance, but alpha, beta and gamma are emitted by radio active substance, just please explain me any other use of radio active substance, then why neutrons are not emitted by the radio active substance, why? any reason, if you know please explain me about that, thank you.
