Paraphrasing - Essay Example They include satellites, televisions, and phones. On the other hand, the ionizing radiations are rays that cannot be smelled, viewed, heard, and even felt. According to a view shared by Liou (2002), the major source of ionizing radiation is radioactive materials that emit beta, alpha, and gamma radiation. Therefore, the commonly known ionizing radiation consists of: beta particles, alpha particles, x-rays, and gamma rays. Up until the late 18th century, the ionizing radiation remained unexplored due to their invisibility, tastelessness, or odourlessness among others. However, there were numerous ordinary materials that emitted small quantities of the radiation. Studies have demonstrated that radiation has various affects on the living organisms by impacting on the cells that build up a living thing. Radiation randomly affects the cell. This implies that a similar amount as well as type of radiation can hit the same cell numerous times, but resulting in dissimilar effects, for instance, every time it strikes there is no effect. On the contrary, it is generally presumed that the more the radiation hits a cell, the higher the odds of an impact from happening. The resulting effect is that the organism may die if most cells are affected. Contrarily, Haffty and Wilson (2012) note that the exposure to penetrating radiation is known as irradiation and it usually occurs when the body is rendered available in part or whole from an unshielding source. An individual is not made radioactive from external radiation. In summary, exposure to the natural radiation by the people occurs daily. The natural radiation originates from various sources, such as over 60 radioactive materials that occur in nature including air, soil, and water. As an example, Radon is a naturally-existing gas that comes from soil and rock. It is the major source of natural radiation. On a daily basis, humans take in
