elements are found to be radioactive. They are categorized as alpha‚ beta and gamma radiations. Alpha particles are positively charged helium-4 nuclei ‚ beta particles are high energy-high speed electrons while gamma rays unlike alpha and beta radiation have no mass and charge and are short electromagnetic waves consisting of high energy photons. While alpha and beta radiations have low and moderate risk of damage‚ gamma rays can cause severe damage to internal organs and even death on skin exposure

really misunderstood‚ like vaccines‚ microwaves‚ and GMOs. But one that is really misunderstood is radiation. First‚ what is radiation? When people talk about radiation or radioactivity‚ they usually talk about microwaves (which don’t cause cancer)‚ X-rays‚ a green thing that glows in the dark‚ the Incredible Hulk‚ or the song by Imagine Dragons. The actual definition is the emission of high energy particles or waves. This can mean many things‚ but the two most common are electromagnetic waves (photons)

worldwide with hyperthyroidism are treated with nuclear medicine (using radioactive iodine). It can also be used in certain kinds of cancers- lymphomas and in the treatment of bone pain in terminally ill patients. How is nuclear medicine different from X Ray‚ CT‚ MRI? In Xray‚ MRI and CT procedures the patients are exposed to radiation from the outside using machines. Hence the radiation from an external source passes through the body. However in nuclear medicine the imaging is based on the radiation coming

Radioactive Isotopes Radioactive isotopes are any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays. Every chemical element has one or more radioactive isotopes. More than 1‚000 radioactive isotopes of the various elements are known.. Approximately 50 of the isotopes are found in nature; the rest are produced artificially as the direct products

emissions are called radiation. The kinds of radiation are electromagnetic (like light) and particulate (i.e.‚ mass given off with the energy of motion). Gamma radiation and X-rays are examples of electromagnetic radiation. Beta and alpha radiation are examples of particulate radiation. Ionizing radiation can also be produced by devices such as X-ray machines. Three types of radiation-induced injury can occur: external irradiation‚ contamination with radioactive materials‚ and incorporation of radioactive

interactions of the tracers within the body‚ in the sequence of specific physiological processes. In vitro applications of radioisotopes have become a most important tool in biochemical analysis. Therapeutic uses of radioisotopes cover from external gamma-ray sources in teleradiotherapy to direct cell irradiation in metabolic therapy. Radioisotopes can be use in medicine in four different ways. They are: 1. Radioactive tracers for diagnostic purposes 2. Radiation source in therapy 3. Research and

Cobalt 60 Mode of decay: Beta particles and gamma radiation Chemical properties: Metallic solid that can become magnetically charged What is it used for? Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation (http://www.cdc.gov/ncidod/dbmd/diseaseinfo/ foodirradiation.htm)‚ a sterilization

It has very a lot of arable land and large reserves of natural resources. The warm climate favours the production of most crops and livestock which is in demand by the population. The country’s economic backbone lies between the performance of the mining and agricultural
