Ionising Radiation

IONISING RADIATION Radioactive substances give out(a) actinotherapy sickness therapy whole of the time. at that place be trey types of nuclear radiation:  of import, beta and da da Gamma. important is the least penetrating, while da Gamma is the most penetrating. Nonethe slight, all three be ionising radiation: they press out knock electrons out of atoms and manikin charged particles. shaft can be harmful, but it can also be useful - the uses of radiation include to: * rule smoke * grass the thickness of paper * treat cancer * sterilise health check equipment. Types of radiation thermonuclear radiation comes from the nucleus of an atom. Substances that give out radiation are said to be  hot. All radiation transfers energy. There are three types of nuclear radiation: * alpha * beta * da Gamma. Radiation can be absorbed by substances in its path. For example, alpha radiation travels simply a a few(prenominal) centimetres in ambience, beta radiation travels tens of centimetres in air, while gamma radiation travels many another(prenominal) metres. All types of radiation become less intense the further the distance from the radioactive material, as the particles or rays become to a greater extent spread out. The thicker the substance, the to a greater extent radiation is absorbed. The three types of radiation penetrate materials in polar ways.

Penetrative properties of different types of radiation important radiation important radiation is the least penetrating. It can be stopped (or absorbed) by a canvas tent of paper. beta radiation Beta radiation can penetrate air and paper. It can be stopped by a dilute sheet of aluminium. Gamma radi! ation Gamma radiation is the most penetrating. plane petite levels can penetrate air, paper or slender metal. higher(prenominal) levels can only be stopped by many centimetres of lead or many metres of concrete. onising radiation whitethorn be man-made, medical x-rays for example, or naturally occurring, such as atomic number 86 gas. There are different types of ionising radiation: * X-rays and gamma rays * Alpha particles * Beta particles * Cosmic...If you want to get a replete(p) essay, order it on our website: OrderEssay.net
