Unformatted sample text from the term paper:
Nuclear technology has been a component of modern medicine for much longer than most would expect. The x-ray and radium, in fact
were both discovered at the end of the nineteenth century! X-Rays quickly became a mainstay in medical diagnosis and radium, misguidedly we now know, was almost immediately embraced as
a miraculous cure-all. The modern age of nuclear medicine started, however, after World War II. It was then that the focus on nuclear medicine rapidly evolved from a
snake-oil approach to an efficient technology. X-Rays are perhaps the most familiar of nuclear technology. Old x-ray technology relied on film exposure.
This meant that the patient was aligned with a piece of film and then exposed to gamma rays. The more modern approach to x-ray technology utilized digital technology
to capture the image. In conventional x-ray technology one was bound to a large degree by the image which was indelibly imprinted on the negative. This is not
long the case in digital technology. In short, nuclear medicine involves the use of radioactive isotopes to diagnose and
treat disease. Various types of cancer, for example, are being treated quite successfully with the introduction of radioisotopes such as Chromic phosphate P 32, Sodium iodide I 131, Strontium
chloride Sr 89, Samarium Sm 153 lexidronam, and Sodium phosphate P 32. Once injected into the body these isotopes emit radiation that targets the cancerous cells.
In applications using advanced technology radioactive materials are internally administered as well and then a variety of imaging techniques are used to interpret the patients status.
