electromagnetic waves) due to disintegration of atomic nuclei of some elements. These cause radioactive pollution. Radiations are of two types ionising and non-ionising. Non-ionising radiations affect only those components which absorb them and have low penetrability. Ionising radiations have high penetration power and cause breakage of macro molecules. Man-made sources of radiation pollution are mining and refining of plutonium and thorium‚ production and explosion and nuclear weapons‚ nuclear

produces hot-spot images‚ which reveal early signs of disease and map how organs are functioning. The low energy gamma radiation it emits‚ the small dose in which it’s injected and it a short half-life (6hours)‚ minimises damage to tissues. The patient’s total exposure to radiation is less than in an X-ray. So far‚ there have been no reported side effects. But use of radiation on the human body can carry many side effects. For instance‚ the high-energy beta-emissions from Co-60 used in radiotherapy

release of nuclear electrons and radiation. This essay will be discussing one of the applications and uses of the radioactive isotopes‚ and it will also state one problem that radioactive isotopes can address. The radiation characteristically meet four kinds: alpha radiation‚ beta radiation‚ gamma radiation and x radiation. Alpha radiation is weighty‚ that includes a very-short variety element and is in fact a homeless helium nucleus. Some examples of alpha radiation are radium‚ radon‚ uranium

Organic chemistry is the study of essentially all substances containing carbon. Organic compounds that contain only carbon and hydrogen are called hydrocarbons. The simplest hydrocarbons are the alkanes which contain only single covalent bonds. Methane is the simplest alkane. It is also the major component of natural gas. Methane contains only 1 carbon in the molecular formula and the structural formula. There is ethane which is 2 carbons‚ propane that is 3‚ butane which is 4‚ pentane which is 5

The properties of nuclear radiation are used to detect their levels. Different types of radiation have different effects on the human body. The key properties that are used to detect nuclear radiation include the ability to: * Geiger-Müller tube Geiger-Müller tubes work using ionising effect of radioactivity. It is best at detecting alpha

Radioisotopes in Medicine Nuclear medicine uses radiation to provide diagnostic information about the functioning of a person’s specific organs‚ or to treat them. Diagnostic procedures are now routine. * Radiotherapy can be used to treat some medical conditions‚ especially cancer‚ using radiation to weaken or destroy particular targeted cells. * Tens of millions of nuclear medicine procedures are performed each year‚ and demand for radioisotopes is increasing rapidly.

Nuclear weapons cause unimaginable death and destruction. Without a doubt‚ these are the most powerful weapons mankind has ever built. However‚ there is also a scientific side to this weaponry which Teddy Roosevelt may have indeed called very big sticks. Nuclear weapons work by releasing the enormous amounts of energy that are contained in the bonds of atoms. The bonds of atoms can be broken in two ways. The first way is by fission‚ and the second way is by fusion. Fission works by the splitting

particles‚ in the form of radiation‚ until a stable nucleus is produced; this is called the radioactive decay. Four isotopes as well as their uses are mentioned subsequently. Americium: Americium is a silvery metal‚ which corrodes slowly in air and is soluble in acid. It has the isotopes: Am-243‚ Am-242 and Am-241‚ with a half-life of 432 years‚ which was the first isotope to be isolated. The isotope Am-241 decays by emitting alpha particles and intense gamma radiation to become neptunium-237

valid points concerning the fear of radiation‚ how easily it finds metal guns and knives‚ and the provacy issue that surrounds X-ray technology (5). Throughout this essay Thomas Frank was able to write about the facts surrounding X-rays and keep hs opinion out of the article therefore giving his readers the chance to form their own belief. This essay was written to analyze which belief to choose. Should the public be against the backscatter X-ray because of radiation exposure or is safety against terrorists
