However, they also make radioactive waste. \u003cbr/\u003eWhen items have no further use and have radioactivity above certain levels, they are known as radioactive waste. \u003cbr/\u003eRadioactive waste can come from a range of activities, including generating electricity from nuclear power stations, treating medical illnesses and conducting research.\u003cbr/\u003e\u003cbr/\u003eDid you know that radioactive waste can be harmful to us? \u003cbr/\u003eEither by irradiation or contamination.\u003cbr/\u003e\u003cbr/\u003eWe’re going to look at these two in this video.\u003cbr/\u003e\u003cbr/\u003eIrradiation is when a person or object is exposed to radiation without coming into direct contact with the radioactive source. \u003cbr/\u003eThe person doesn’t make direct contact with the radioactive barrel, but since irradiation can happen at a distance, the person is still at risk. \u003cbr/\u003e\u003cbr/\u003eThe damage to the person only happens whilst the person is in the area of the radioactive waste. Therefore the person is only exposed to radiation for a short time, and so receives a low dose of radiation.\u003cbr/\u003eIrradiation can sometimes be useful, particularly during cancer treatment. \u003cbr/\u003e\u003cbr/\u003ePeople are irradiated in an attempt to remove cancerous cells from their body. \u003cbr/\u003e\u003cbr/\u003eIrradiation is also used to sterilise surgical equipment, or to remove bacteria from fruit in supermarkets. The objects don’t become radioactive themselves, and so are safe for use or consumption.\u003cbr/\u003e\u003cbr/\u003eContamination is when a person actually comes into contact with radioactive wastes. \u003cbr/\u003eThe person takes the radioactive source away with them, and so are exposed for a longer period of time and consequently have a higher dose which can lead to more damage. \u003cbr/\u003e\u003cbr/\u003eContamination can happen in a variety of ways: from picking up a source, to breathing it, to ingesting it. \u003cbr/\u003e\u003cbr/\u003eContamination is used in medicine, by injecting radioactive tracers into the body to see possible blockages. Radioactive tracers are also used to find leaks in water pipes.\u003cbr/\u003e\u003cbr/\u003eRadioactive waste can remain hazardous for a very short or a very long period of time, depending upon the different half lives. \u003cbr/\u003e‘Half lives’ mean the level of hazard of the radioactive waste reduces with time.\u003cbr/\u003e\u003cbr/\u003eIf we start off with a kilogram of radioactive waste that has a half life of 100 years, \u003cbr/\u003eafter 100 years we will have 500g of radioactive waste. \u003cbr/\u003eAfter another 100 years there will be 250g of it \u003cbr/\u003eand so on. \u003cbr/\u003e\u003cbr/\u003eEventually the amount of radiation will decrease until it reaches the same level as background radiation. \u003cbr/\u003e\u003cbr/\u003eFor medical contamination that involves injecting radioactive sources, isotopes that have very short half-lives are selected. The half life is long enough that they stay active for detection to be done. But short enough that they reduce to low-risk levels as quickly as possible.\u003cbr/\u003e\u003cbr/\u003eBackground radiation comes from artificial and natural sources around us, that we experience daily. \u003cbr/\u003eIt is low in magnitude so it isn’t harmful. However, for some radioactive wastes to reach this low background level it may take several thousand years. \u003cbr/\u003e\u003cbr/\u003eSo just how harmful is radioactive waste? The answer depends on the half life of the waste and whether a person is irradiated or contaminated. It’s like asking, how long is a piece of string?\u003cbr/\u003e\u003cbr/\u003eWe’ve now learned about the differences between irradiation and contamination.\u003cbr/\u003e\u003cbr/\u003e\u003cbr/\u003e\u003cbr/\u003eCREDITS\u003cbr/\u003eAnimation \u0026 Design: Chloe Fyvie Adams\u003cbr/\u003eNarration: Dale Bennet\u003cbr/\u003eScript:
