Evolving environmental protection considerations have provided the impetus to improve disposal technologies, and, in some cases, clean up facilities that are no longer in use. Iodine used for curing thyroid cancer. Radioactive waste can be in gas, liquid or solid form, and its level of radioactivity can vary. The machine aims those radiations at the cancer. Metabolic Research: – Radionuclide is used extensively in metabolic studies and genetic engineering. Here is a list of isotopes with there half life period and uses: Used in Biomedical researches: – The Radioactive isotopic materials are very essential in curing many dreadful diseases like AIDS, cancer and Alzheimer’s disease. Since infected cells can be killed by these radiations. Many uses of radiation help to ensure the high quality and safety of our daily lives. Mammography: Mammography is a special type of x-ray that is used for the detailed images of breast. Radioactivity was unintentionally discovered by HENRI BECQUEREL. Nuclear medicine uses radiation to provide diagnostic information about the functioning of a person's specific organs, or to treat them. Human curiosity drove inquiring scientists to harness the power of an atom. Other uses of radioactivity. Emitted gamma rays can be diagnosed by gamma cameras and computer development of the causing images allows quick and relatively non-invasive assessments of injury or physiological impairments. Chemical Reaction Imaging: – the latest single photon emission typography (SPET) on positron emission tomography (PET) enable scientists to watch colour images of chemical reactions in living tissue and, in particular, to trace opioid molecules- naturally occurring morphine-type drugs – which eliminate pain within the brain. Radioactive sources are ubiquitous, in industrial, medical, research and lifestyle applications. One hundred years ago, a group of scientists unknowingly ushered in the atomic age. One century ago, a group of experts unknowingly ushered in the atomic era. Radioactive isotopes help doctors and researchers know about body structures. The total radiation dose conferred to patients by the majority of radiopharmaceuticals used in diagnostic nuclear medicine studies is no more than what is conferred during routine chest x-rays or CT exams. Sterilizing medical products . Chemical Effect Imaging: - the latest solitary photon emission typography (SPET) on positron emission tomography (PET) enable experts to watch coloring images of chemical type reactions in living structure and, in particular, to track opioid molecules- naturally occurring morphine-type drugs - which eliminate pain within the mind. In parallel the country was also witnessing regular induction of huge number of X-ray … Wide range of high-qualified, customized solutions for worldwide nuclear applications as radiation monitoring and neutron flux measurements. Application of radiation in medicine Chapter 9 Radiation used for diagnostic purposes In this chapter we shall discuss the use of radiation of different kind for medical imaging. Knowledge of radioactivity helped scientists to work out the structures of atoms. Hence they are really trusted in caner treatments. Although there is a wide range of applications, but the most used are X-Rays to detect fracture in bones, radiology where patient is injected with radioactive material, cardiology in which heart scanning is done. Applications of radioactivity and radioisotopes. One example of a diagnostic application is using radioactive iodine-131 to test for thyroid activity (Figure 15.4 “Medical Diagnostics”).The thyroid gland in the neck is one of the few places in the body with a significant concentration of iodine.
