Question

please help .....what is radiation and radioactive rays????

Answer 1

radio active rays are defined as these are three types of rays which are emitted by radioactive element on isotopes they include alpha beta and gama

Answer 2

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

There are 3 main types of radiations:-

1) alpha particles -released by high mass, proton rich unstable nuclei. The alpha particle is a helium nucleus; it consists of two protons and two neutrons.

2)beta particles -emitted by neutron rich unstable nuclei. Beta particles are high energy electrons.

3)gamma rays -electromagnetic waves of very short wavelength and high frequency. Gamma rays are emitted by most radioactive sources along with alpha or beta particles.
