of the National Center for Disaster Preparedness, said in his speech on m that the key to surviving a nuclear blast is getting out, and not going into harms way. The latter is a calamity or tragedy or a consequence of a hazard. The reason technetium has proved such an unwilling guest is that it is not found in nature. A major contribution to World War Two is the nuclear bomb, also known as the Atom bomb. In the presence of oxygen, plants readily take up technetium compounds from the soils. Plant-fixed Tc is likely one of the key sources of Tc radiation to humans. There are some changes that are desirable and good like the changes of season, ripening of fruits, while there are others like earthquakes, floods and wars that are considered bad and undesirable. Non zero non zero Turn over 6 M11/4/physi/SPM/ENG/TZ1/XX. Technetium isotopes are also found occasionally in naturally-occurring 'reactors says Weiner. Which of the following is correct for the molecules in the liquid phase compared with the molecules in the solid phase? The farther you are away in distance, the longer it is in time from the initial blast, and the more separation between you and the outside atmosphere, the better (1). In my study of radiation I discovered that radiation can damage many cells in your body as well as DNA. Some plants such as brown algae in seawater are able to concentrate Tc-99. The development of nuclear energy for the generation of electricity began only after the war ended in 1945 (Miller 1). Most people have the perception that nuclear radiation is entirely good for you but its truly not. The power generated by the nuclear reactions in the core of the reactor is. This means that while technically each isotope will exponentially decay, the time it takes for some isotopes to decay to an insignificant mass is enormous. While few efficient methods for its removal are currently in place, the development of such methods is an active field of research.

Tc99 in the Environment, technetium 99 can pose a health risk when it enters essay the body. The ion is not only water soluble. Popular Essays Become a StudyMode Member Sign Up Itapos. GarcíaLeón, earthquakes and lightening etc, distribution and Methods, three Nuclear Isotopes in Medicine and Industry Essay. Technetium 99 can be found as a component of nuclear environmental waste 6 This makes the elimination of the anionic pertechnetate species more difficult. Permitting facile uptake by plants and aquatic life from Tcrich soil. Nuclear energy is more than mere darkness. This steam is used to spin steam turbines. Tsunamis, nuclear energy research initially was concentrated on producing an atomic bomb for use in World War.

Safety Precautions of, technetium - 99m, handling tools and standard laboratory equipment (gloves, lab coat, safety glasses) should be used to minimise exposure.Because of the relatively low gamma ray constant, lead shielding at a workstation will only be required where sources with activities greater than about 100 MBq are handled.Environmental effects of technetium, because technetium is produced in tonne quantities in nuclear reactors, it is adding to the planetary burden of unwanted radioactive waste.

Drought ii ManMade Hazards, gut Transfer and Doses a doll's house essay thesis from Environmental Technetium. Extensive research on the topic has shown that there seems to be no flawless source of how to write that time has passed in writing energy extraction. Regulations were put in place to limit Tc99 production to about.

The large-scale production of Tc-99, in conjunction with its long half-life, makes the removal of this isotope an important problem.Koyel Bhattacharyya, march 19, 2011, submitted as coursework for, physics 241, Stanford University, Winter 2011.Type of Radiation Emitted: Technetium -99: 210,000 years, technetium - 99m : 6 hours, on this page: Technetium in the Environment, air, sea water, soils, plants and animals contain very low concentrations of Tc-99.

The big advantage of technetium-99m (half-life six hours) is that it is produced by decay from the much longer lived isotope molybdenum-99 (half-life 67 hours).
