Types and properties of radiation
1.) alpha
The nucleus of a helium atom Protons and neutrons are electrically charged particles, each 2 + 2 with a mass number 4 Single sheet of paper or two, it can be compatible. Ben approached a negative l. The substance can be ionized well. It was quick energy
2.) beta radiation
Electrons are particles with properties like -1 is charged with mass equal to the mass of the electron. High-energy beta radiation in an electric field converge anode.
3.) Gamma ray
Is electromagnetic wave whose wavelength is very short. There is no charge and no mass No excursion in electric field. A maximum penetrating power
