Radiation Exposure among Health Care Workers Introduction Radiation is actuality of life and in terms of defining; it is the emission (sending out) of energy from any source. We live in a world in which radiation is unsurprisingly present everywhere and has been since the creation of this planet. Light and heat from nuclear reaction in sun are crucial to our survival. Radioactive materials occur naturally all through the environment and our bodies contain radioactive materials for example carbon-14, and potassium-40 naturally (Knoll, 1989). All life on Earth has evolved in the presence of this radiation. One can categorize radiation according to the effects it produces on matter, into non-ionizing and ionizing radiation. Non-ionizing…show more content…
Figure 1 below depicts the exposure sources of radiation. Source: 2014. Where does radiation exposure come from? Sources and distribution of average radiation exposure to the world population. http://www.who.int/ionizing_radiation/env/en/ Radiation is one cause, along with hundreds that result in cancer. Radiation is invisible to the naked eye, making it more difficult for our senses to detect. The fundamental background of cosmic rays, gamma rays, and natural radioactivity within the body gives rise to an annual dose of about 1 mSv or more to an average person in the world. It is simple, in some situations, to control non-natural sources of radiation for the reason that we can adjust or eliminate the procedure producing the radiation, however there is always a balance to be made. It is vital, for example, to be aware of the doses from medical x-ray examinations, but it would not be smart to lessen the doses where it would result to a loss of vital diagnostic information that could not have been found with radiation. This is all part of the cost and benefits of using radiation. Radiation affects people by depositing energy in body tissue, which can cause cell damage or cell death. In several cases there may be no obvious effect. In other cases, the cell might survive but grow to be abnormal, either temporarily or permanently. Furthermore, an abnormal cell could become malignant. Both large and small doses of
