what are radioisotopes . ...
-at present there are up to 200 radioisotopes used on a regular basis, and most must be produced artificially.
-radioisotopes can be manufactured in several ways.
-common way is by neutron activation in a nuclear reactor - involves the capture of a neutron by the nucleus of an atom resulting in an excess of neutrons (neutron rich)
-some radioisotopes are manufactured in a cyclotron in which protons are introduced to the nucleus resulting in a deficiency of neutrons (proton rich). ...
-In certain imaging procedures, radioisotopes are injected. ... Radioisotopes can serve as an internal source of radiation to destroy harmful cells in cancerous or benign tumours, or those that block coronary arteries after angioplasty
-therapeutic radioactive materials can be placed into the body in several ways. Physician specialists in radiation therapy can physically place sealed sources of gamma or beta emitting isotopes into the tumour, organ or vasculature in a procedure known as brachytherapy
-nuclear Medicine involves the use of radioactive isotopes (radioisotopes) to prevent, diagnose, and treat disease
-able to assess the functioning of the heart, kidneys, brain, thyroid gland and other organs of the body without the need for invasive exploratory surgery. ...
-Radioisotopes can be used in two ways to treat prostate cancer. Tiny radioactive implants can be put into the prostate to give very localized doses of radiotherapy
-another way of using radioisotopes is for prostate cancer that has spread to the bones. ... But unfortunately it will not get rid of the cancer completely
-breast cancer - radioisotopes are used to check for metastasis to the bones or the liver
-radioactive drugs can help save the lives of the many organ transplant patients, prematurely born children, AIDS patients and others living with weakened immune systems.
