mYP Year 2 Science Summative Assessment UNIT: ATOMIC STRUCTURE AND THE PERIODIC TABLE Sarah Wulff Khan 7A Radioisotopes What is an isotope? Isotopes are atoms of the same element that have a different number of neutrons but the same number of protons and electrons What is radioactive? Emitting (produce and discharge) (something, especially gas or radiation).or relating to the emission (the production and discharge of something) of ionizing radiation or particles. What are radioisotopes? Radioisotopes (a radioactive isotope.) in Medicine Nuclear medicine (the branch of medicine that deals with the use of radioactive substances in research, diagnosis, and treatment) uses radiation (the emission of energy as…show more content…
Tens of millions of nuclear medicine procedures are performed each year, and demand for radioisotopes is increasing rapidly. Sterilization of medical equipment is also an important use of radioisotopes. Radioisotope therapy brings radiation directly into the cancer cells. Normally you are supposed to be given the radioisotope or radionuclide (a radioactive nuclide) usually as a capsule, drink or injection directly into a vein. Your cancer cells absorb the radioactive substance more than normal cells. This means they receive a higher Quantity of radiation, causing them to die! There are a lot of different types of radioisotope treatments depending on what type of cancer you have! There is: Iodine-131 is used to treat certain types of thyroid cancer and some other rarer types of cancer. You may need to stay in hospital for this treatment. Strontium-89 and samarium-153 is used to treat some types of secondary bone cancer (Secondary cancer in the bone is the result of cancer cells spreading to the bone from a primary tumor somewhere else in the body). Strontium can help reduce
