    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.…

    Each year, roughly 25 million procedures are carried out using technetium 99m (Tc-99m) and around 80% of all nuclear medicine procedures involve Tc-99m. (IAEA, 2008). However, many people don’t realise that our advancement into this modern age of radioisotopes is all thanks to the radioactive element uranium. First used to produce the destructive Hiroshima bomb during World War 2, uranium is now used to create the commonly used radioisotope Tc-99m and many other radioisotopes. Tc-99m is used in…

    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…
