"Importance of Radioisotopes and Isotopes"

Download file to see previous pages Some of the isotopes undergo radioactive decay over time, therefore, known as radioactive isotopes. On the other hand, those isotopes not been observed to undergo any form of decay are known as stable isotopes. In general, isotopes have similar chemical properties but different physical properties. For example, hydrogen has three different isotopes (fig 1); 1H, 2H, and 3H. Hydrogen 1 or protium is the most abundant isotope.
As they all have similar chemical properties they can form similar bonds. H2O and D2O are some examples but they have different physical properties. H2O has melting point of 0.0oC and boiling point of 100.0oC but D2O melts at 3.82oC and boils at 101.4oC. (Stoker 55).
Isotopes have various applications in different sectors. In the medical field, radioactive and stable isotopes are used in medical procedures for the purpose of diagnosis and therapeutic use. Isotopes have a significant application in biomedical research field as well as research in physics, biology, chemistry, geosciences and other branches of science and technology.
Isotopes can be used in various ways in the various fields discussed above. They are generally helpful because of their emission properties. Isotopes with short half life decay and emit various radiations such as beta emissions which can be detected by various means. Therefore, they can be used as ‘tracers’. For example, scientists can measure the uptake of nutrients in a plant by using a radioactive isotope of phosphorous. 32P containing compound can be introduced in the soil which is taken up by the plant. It has a short half life of about 2 weeks and the rate of uptake can be found my measuring the time taken for it to appear in the leaves. It can be traced in the leaves by detecting the beta emissions. (Kotz, Treichel and Townsend 1086). Many other applications of radioactive isotopes apply similar technique.
There are many applications of isotopes in the field of medicine. Iodine is an essential ...Download file to see next pagesRead More

Importance of Organisational Values Importance of Organisational Values The new reform health care bills Health and social care as we all know is vital for a country’s development and for the future of its citizens. Its success is measured through achievements, goals reached and most importantly customer satisfaction. There are different factors all together to take into consideration, which will contribute to effectiveness. These are what I have come to recognize, that are, good leadership, less waiting times for patients, highest quality of care, open culture in an organisation, government recent change in law (NHS Reforms), empowerment of staff and patients, and finally performance management.

Agriculture's importance economic progress
...?Introduction Agriculture which is predominantly the base of systems of economy in most of the under developed countries is the primary occupation ofrural people in those countries. It is primary because it supplies basic necessities of human life, provides basic inputs for industries and, in addition to these, purveys goods for exports and other purposes. “. . . the rise in agricultural production . . . makes important contributions to general economic development and that, within considerable limits at least, it is one of the preconditions which must be established before a take off into self sustained economic growth becomes possible” (Nicholls, 1970). Earlier development economists like Arthur Lewis (1954), Hirschman...

...). Isotopes rich in protons are manufactured in cyclotrons, in medicine the field of medicine. During therapy, a lot of factors govern the radioactive isotope selection in the search to administer the right dosage to a patient. This is the reason why all physicians are advised to carry out a thorough discussion with the patient before commencing a therapeutic exercise. If a wrong therapy is administered to a patient, the results can be very devastating or even cause a patient’s life (Rana, et al., 2012). Even though, the use of therapeutic radiopharmaceuticals has proven to deliver positive outcome up to date. In conclusion, radioisotopes are widely used to improve the imaging used in...

The Use of Isotopes in Medicine
...to detect and report absence or presence of various radioactive isotopes within the body. These isotopes can be detected even at very low volumes and concentrations (Prvulovich and Bomanji, 1998, p. 1144). As a result, radioisotopes provide a safe way through which biochemical analysis is achieved. Ramamoorthy and Binukumar (2010, p. 46) explains that the process of biochemical analysis involves labeling of various molecules within biological samples out of the body or in vitro. This is commonly used by pathologists to determine the levels and concentration of various elements within body samples. For example the constituents of serum, blood, antigens, urine, drugs and hormones can be...

...produces different isotopes such as carbon-11, carbon-13, and carbon-14. This means that isotopes of carbon have different mass numbers 11, 13 and 14 respectively which is calculated by adding the six protons with the five, seven, and eight neutrons. Greenblatt and Carroll highlight that same element isotopes have similar chemical characteristics, but they may have other differences in many ways such as their stability and radioactivity (11). Stable and Radioactive (Unstable) Isotopes Radioactive or stable are the terms used to refer to isotopes; scientifically, isotopes are said to decay by halflife, which is the difference in time half...

Isotopes in archeology
...?The etymology of the word isotopes can be traced back to the Greek words, isos equal and topos meaning place. The physical of an isotopeis that it is a variable of an element with a similar atomic number but differ in atomic mass, therefore, isotopes of an element are the different arrangements of neurons for the same proton. Except for hydrogen, all other known stable atoms have protons and neutrons in equal numbers, this balance is absent in the case of isotopes. The atomic number of an element is determined by the number of protons present on its atom, while the atomic mass is calculated based on the present neutrons (Saunders and Katzenberg, 1992). Isotopes are...

...to the difference, a single element has the capability of existing in many forms for instance oxygen can exist as oxygen- 15, oxygen- 16 or oxygen- 17. This paper aims having a comprehensive discussion of isotopes, outlying their uses in archeology as well as looking at the future of isotopes in this area of interest. Isotopes are categorized into two main groups; stable and unstable. White (1998) asserts that stable isotopes are those that do not decay over time, while the unstable ones undergo through an ionizing radiation referred to as radioactivity. Isotopes that give off this ionizing radiation are called radioisotopes, for...

Radioisotopes in Medicine
...Radioisotopes in Medicine Every chemical element has got species of atoms which may be one or more than one with same atomic number i.e. having the same number of protons in the nucleus; same position in the periodic table; similar chemical properties but different atomic masses and physical characteristics. These species are called isotopes of the same element. These isotopes are possessed by all elements. These isotopes have been divided into stable and unstable. Unstable isotopes are those which undergo radioactive decay. In atoms of all elements, the number of protons in the nucleus determines the atomic number; these atoms have the same number...

A lot of important things were brought to Europe from Muslim regions, “such as Arabic numerals with the principle of the zero vital to the advancement of mathematics and the use of algebra” (Fatoohi 91). The idea of promotion of adequate education for its citizens is a requirement of a truly Islamic government. “Education is a right for all individuals and the required moral duty of every capable Muslim” (Asad 212). So, intelligent, able and skilled people of the Islamic society do not hesitate to educate themselves – this is not only religious education, they are required to get knowledge in worldly affairs they need....
