Paraphrase..rewrttin - Essay Example However, cancer treatments are conducted by two radiation methods i.e. ionizing and non-ionizing radiations. The ionizing radiation includes X-rays and Gamma rays, as (Yale 2001) identified a disadvantage of passing ionization radiation process from the body. The ionization radiations are absorbed by thick tissues in the body that enables them to be chemically reactive resulting in a cell damage. The study concluded restrictions for using ionization radiation to a minimal as it can raise issues related to human health. Disclosure to ionization radiation is another factor that needs consideration, as there are evidences available that has linked disclosure of low-level ionization radiation by the doses, which are given for the development of cancer by medical imaging. An inclusive review of biological and epidemiological data associated with health risk of ionization radiation exposure was conducted by the ââ¬ËNational Academy of Sciencesââ¬â¢ National Research Council. Moreover , the review is recently published in the form of a report named as the Biological Effects of Ionization Radiation (BEIR) VII Phase 2. In the report, the epidemiologic data demonstrated the survivors of the atomic bomb along with the population living near the facilities that are equipped with nuclear technology throughout the releases of Chernobyl, which is a radioactive material. Moreover, report also includes the workers who are exposed by occupations and populations, who faced exposure with the aid of therapeutic and diagnostic medical studies. Commonly used CT examinations that includes radiation doses that are received by humans, amplify the risk of cancer. For instance, increased risk of cancers is identified within the survivors of Hiroshima, as Nagasaki atomic bombs affects on these people were exposed by the ranges of 10 to 100 milli-sieverts (mSv). This value is equivalent to a single CT scan radiation exposure and patients do conduct CT scans multiple times during the tr eatment. (Smith-Bindman et al 2009) Risks involved in the use of Ionizing radiation The first hard tumour that was found, resulted from the ionization radiation effects. Consequently, securing from the ionization radiation methods that facilitates medical procedures has grabbed significant concerns. Predominantly, the rise in various medical procedures incorporating ionization radiation(Davros et al 2007). In order to protect people from this kind of radiation, an establishment of an International Commission for Radiation Protection took place in 1928. "The International Commission on Radiological Protection (ICRP) estimates that the average person has an approximately 4-5% increased relative risk of fatal cancer after a whole-body dose of 1 Sv. However, other studies on multiple cohorts of radiation workers have largely failed to establish statistically significant cancer risks. When multiple occupational cohorts were combined and evaluated in a somewhat systematic way, a combined excess relative risk of cancer death of just less than 1% was estimated" (Cardis et al 2005). In between years 1950s and 1960s, many traces become visible conclusion that the ionization radiation is dangerous for humans. Likewise, experimentations were conducted on rats by passing X-rays has also concluded the contribution of ionization radiation at low levels causing imminent deaths. Similarly, there are many proofs to conclude that the frequent use of radiation can cause
