Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946, nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid, to diagnose thyroid disease, and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine

small intestine”. What does it have to do with nuclear medicine and radioactive elements? That’s a good question. It has to do with radioactive elements because the meal, liquid, or both are mixed with a little bit of radioactive material, than gamma rays are placed over the subjects stomach to track the amount of radioactivity that decreases in the stomach.  Gastric emptying studies use radioactive elements by using radioactive material.  What is a radioactive tracer? Another good question. That

at sea level. Radioactive waves are also transmitted through some fabricated technology, soil, and rocks. The majority of people pose the question why do doctors or nurses where aprons when giving an x-ray. This is to protect them from radioactive waves. Nurses give countless numbers of x-rays a day. While you

Conclusion Abstract This paper goes over radiation safety precautions and all the health risk dealing with radiation. I will discuss the discovery of radiation, non-iodizing and iodizing radiation, natural exposure to radiation, Alpha, Beta, and Gamma radiation and how they affect us. Also the paper will be going over radiation from human activities: underground miners, radiologists, medical

types, however, is the type of radiation used. The most effective types include electron beam radiation, gamma ray radiation, and x-ray radiation. Electron beam radiation is the shortest in terms of time needed to irradiate the food, but it also does not penetrate very deep, only about half a centimeter. This type of ray radiation is used to merely disinfect things like wheat and some grains. Gamma ray radiation is the use of Cobalt-60 in most places to irradiate the food. In fact, this type of radiation

tracer) or genetically (for example with HSV1-tk reporter gene) labeled . In order to use this nuclear imaging modality radiopharmaceuticals (also called tracers) are given internally (i.V. or orally). The Radiopharmaceuticals emitting penetrating gamma rays are used for imaging, where the radiation has to escape the body before being detected by special scans. The two major nuclear imaging modalities used in pre-clinical

They also have a less powerful ionizing rate compared to alpha particles. Gamma rays are energy, also known as electromagnetic radiation. They have no charge or mass. They move through the air extremely quickly (at the speed of light) and to ionize them, they need to directly hit the nucleus of an atom. This suggests that gamma rays have a very low ionizing rate and can travel much t=further through the air compared to alpha and beta particles. Nuclear-fuelled

) Description of the HPGe gamma-ray spectrometer A high resolution gamma detection system was used for gamma analysis. This system consist of an ORTEC hyper pure germanium detector (HPGe), model number GEM- 15190, coaxial type detector with a serial number 27-P-1876A recommended operating bias, negative 3 Kv. The detector used has crystal diameter 49.3 mm, and crystal length 47.1 mm. The HPGe detector has a full width at half maximum (FWHM) 0.9 keV at the 122 keV gamma transition of Co-57 and 1.9

effects on society. Explain briefly how the applications work. Include some of the scientists involved in their discovery and development. Simply put radiation is energy or particles flying through space. Radiation comes in three forms Alpha, Beta and Gamma radiation, all three types have vastly different applications and levels of strength. The most common type of electromagnetic radiation used in the medical is known as ionising radiation, that form of radiation is far more powerful than non-ionising
