Technetium-99m

goes off-line shortages happen and resources are rationed. This means that patients in hospitals are prioritized and not all the patients that may benefit from the use of these isotopes get diagnosed as early. If their problem turns out to be something of significance like osteosarcoma, not having access to an early diagnosis would mean the patient is now in a much worse state of health and that could’ve been avoided. The Australian Nuclear Science and Technology Organization (ANSTRO) stated that a gram of Mo-99 is worth $46 million (national Academies Press, 2009). Ron Cameron, head of nuclear development Nuclear Energy Agency, has predicted that the price of Mo-99 could increase 7-fold, due to the radioisotopes shortage. Production of Tc-99m was halted in 2016 at the Chalk River facility even though it is set to shut down in 2018. Because of Tc-99m’s half-life it cannot be stockpiled which also creates more problems for purchasing industries. If a reactor is shut down for a week, that can’t be replaced.…

Gallium-87 , Gallium-86 citrate , Technetium-99 , Iodine-123 and Iodine-131 . there are all these different uses pigments have benefits and harm . Firstly , we will talk about Iodine-123 is used to diagnoses the patients . It use for routine scan the time of imaging 4-6 or 24 hours and dosage 100-400 microCi po , Also we can use for thyroid cancer the time of imaging 4-6 or 24 hours and dosage 1.5 mCi po . The photon energy of iodine-123 is 159 keV . The half life is 13 hours . It has…

the mid 1920’s when George de Hevesy administered radionuclides to lab rats. Introducing these radionuclides displayed metabolic pathways between substances within the rats. These reactions were called tracers. Frederic and Irene Joliot-Curie were the first to experiment with artificially produced radionuclides. By irradiating foil with polonium artificial radioactivity was created. The work done by the Joliot-Curie’s was later built upon by other scientists such as Roentgn, who invented the…

Phosphorus. The Silicon which was exposed to radiation is sliced into chips, used for a variety of advanced computer applications. This process increases the efficiency of electrical conductivity in the silicon which is an essential feature for the electronics industry (including; video cameras, and air conditioning units). The reaction is as follows: Medical radioisotopes are also created at ANSTO, Technetium-99m is the most important, since it is used in 80% of nuclear medical scans,…

Forensic Anthropology Bone Scans How do bone scans help forensic anthropologist figure out how people died? There are many different bone scans that can help them look at different fractures in the bones.The bone scans can help figure out if the deceased was abused,or brought around drugs. Some types of scans that look at bones are the Skeletal Scintigraphy, Dexa Scan, and a Bone Scan. All of these bone scans are used in different ways to help figure out how people died. “Skeletal…
