This is very useful because they can see the body processes actually working, rather than just looking at still pictures.

This is called "Radiotherapy", and works because healthy cells can repair themselves fairly well when damaged by gamma rays - but cancer cells can't. Getting the dose right is very important!]]> 2017-02-27 15:23:52 UTC https://padlet.com/ramirseb000/9len0tkl8dys/wish/156437838 How They're Made ramirseb000 https://padlet.com/ramirseb000/9len0tkl8dys/wish/156438196
Gamma rays are able to ionize other atoms (ionizing radiation), and are thus biologically hazardous. The decay of an atomic nucleus from a high energy state to a lower energy state, a process called gamma decay, produces gamma radiation.

An example would be using radioactive iodine to treat cancer in the thyroid gland.]]> 2017-02-27 15:28:56 UTC https://padlet.com/ramirseb000/9len0tkl8dys/wish/156440190 valenale000 https://padlet.com/ramirseb000/9len0tkl8dys/wish/156440849 This also explains why damage is done by radiotherapy to other rapidly dividing cells in the body such as the stomach lining, hair follicles , and a growing fetus.]]> 2017-02-27 15:30:18 UTC https://padlet.com/ramirseb000/9len0tkl8dys/wish/156440849
