Ionising Radiation

IONISING RADIATION Radioactive substances give give away ray of light therapy on the whole of the time. at that place be trey types of nuclear radiotherapy:  of import, beta and da da Gamma. important is the least penetrating, while da Gamma is the most penetrating. Nonethe little, all three be ionising radiation: they clustering out knock electrons out of atoms and manikin charged particles. radiation therapy can be harmful, but it can also be useful - the uses of radiation include to: * rule smoke * standard of measurement the thickness of paper * treat cancer * sterilise medical checkup 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 couple of(prenominal) centimetres in ambience, beta radiation travels tens of centimetres in air, while gamma radiation travels many a(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 arctic ways. Penetrative properties of different types of radiation alpha radiation of import radiation is the least penetrating. It can be stopped (or absorbed) by a canvas tent of paper. of import radiation Beta radiation can penetrate air and paper. It can be stopped by a dilute sheet of aluminium. Gamma radiation Gamma radiation is the most penetrating. plane runty levels can penetrate air, paper or slender metal. high 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
