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 4. Sterilization The radioisotope therapy has been available to those disease conditions in which extensive cellular malfunction exists. Diagnostic radiopharmaceuticals are

configuration of Vanadium is 1s2 2s2p6 3s2p6d3 4s2. Vanadium also forms different isotopes. Natural Vanadium is a mixture of the two stable isotopes‚ Vanadium-50 (0.24%) and Vanadium-51 (99.76%). Vanadium-50 is somewhat radioactive‚ with a half life exceeding 3.9 x 1017 years. Vanadium has other radioactive isotopes‚ but they have half-lives shorter than an hour. They range from Vanadium-40 to Vanadium-65‚ and none of these isotopes are found in nature. There are also different ions of Vanadium that normally

thousands of time greater than conventional battery sources. Hence‚ there is an urgent need to harvest enormous amount of energy released naturally by the tiny bits of radioactive material. Unlike conventional nuclear power generating devices‚ these batteries do not rely on the fission or fusion reactions and do not generate any radioactive material as by-product. They promise clean‚ safe‚ reliable and almost endless energy without any drop in its yield or efficiency during its entire life span-which

1. One medical use of radioactivity is the treatment of cancer. Yes‚ radiation therapy is utilized for treatment of many types of cancers. Radiotherapy: a method to destroy cancer cells by irradiation with radioactive isotopes or X-rays. a. Explain briefly how radioactivity can cure some types of cancer. beta particles can cure skin cancer but not inside the body The main scooby dooby on this is that the biological damage done to some kinds of cells by exposure

WATER AS OUR NATURAL RESOURSE There are more than 326 million trillion gallons of water on Earth. Less than 3 % of all this water is fresh water and of that amount‚ more than two-thirds is locked up in ice caps and glaciers. With so much water around it seems like there is enough to see us through for millions of years. But did you know that even water‚ which seems to be in abundance‚ might one day become scarce? Each time you throw something as garbage‚ think of where it will finally end up. Whether

Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase

Both of these isotopes emit high energy beta particles which can blacken x-ray film. Sulfur-35 is most commonly used as it emits lower energy ‚ less dangerous beta particles than phosphorus-3. Polyacrylamide gel electrophoresis is then used to seperate and analyse the

These two experiments led to the discovery of radioactivity. Radioactive decay is the transformation of an unstable atomic nucleus into a lighter one where radiation is released in the form of alpha particles‚ beta particles and gamma rays‚ which are the three types of radiation. Gamma rays are the most dangerous because
