Explain with neat labelled diagram the nature of radioactive radiation

1.	Explain with neat labelled diagram the nature of radioactive radiation.
Answer» When radioactive radiations are allowed to pass through two oppositely charged plates they get separated. This method was introduced by Rutherford in 1902. Rutherford and Willard studied the radiation emitted by radioactive substances. For this purpose, the rays were allowed to pass through an electrical field and a photographic plate was held in their path. It was found that the radiation was divided into three types. One type of radiation deviated slightly towards the negatively charged plate, while the second type of radiation deviated substantially towards the positively charged plate. However, the third type of radiation did not deviate at all in the electrical field. The rays which deviated slightly toward negatively charged plate are called alpha rays. Those which deviate substantially towards the positively charged plate are called beta rays and those which did not deviate at all are called gamma rays.
