An isotope undergoes radioactive decay by emitting radiation that has no mass. what other characteristic does the radiation have?

a. some shielding required

b. positive or negative charge

c. low penetrating power

d. no charge

Answer : Option D) No charge

Explanation : An isotope undergoes radioactive decay by emitting radiation that has no mass. The radiation will not have any charge as it does not has any mass it will not emit a radiative charge.

It is known that there are some unstable radioactive isotopes which has no mass and the radiation thus has no charge in it.
