Radiation

RADIOACTIVITY of import is blocked by make-up. Its positively aerated. Its touched by magnetised field. They come home plate gold f oil colour. Alpha radiation syndrome is aforementioned(prenominal) as Helium atom. It is define by 4 He or 4 ? 2 2 genus Beta is negatively charged and is blocked by magnetic field. Its stopped by Aluminium. It is be by 0 e or 0 ? -1 -1 da da da Gamma is not affected by magnetic field. It loafer penetrate lead. They are electromagnetic waves. Most isotopes are mobile i.e effect break into small parts to release Alpha, Beta, and Gamma rays, a process called hot collapse. half life is a time taken for one-half the atoms to decay.

Alpha decay: Radium(Ra) decays by Alpha liberation to pose Radon(Rn) 226 Ra 222Rn + 4 He 88 86 2 Beta decay: Polonium (Po) decay by Beta emission to grab down Astatine (At) 218 Po 218 At + 0 e 84 85 -1 Gamma emission Gamma emission causes no turn in mass tot or atomic number. Half life This is the time taken for half the atoms to decay. Uses of radioactivity: 1. radioactive fertiliser batch be ply to plants and then traced through the plant using a Geiger counter. This method acting is affiance to develop better fertilisers. 2. It female genitals be utilise to follow conditions of internal body organs like kidneys. 3. It is use to get word leaks from a pipeline carrying oil or gas. This saves take outdoor(a) time. 4. Sterilising. Gamma-rays can be used to kill bacteria, mould and insects in food for thoughts, even after the food has been packaged. This prolongs the shelf-life of the food. 5. Thickness control. In write up mills, the thickness of the paper can be controlled by quantity how much beta-radiation passes...If you want to get a full essay, ordination it on our website: Orderessay
