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

This report will give an overview of factors to consider when formulating an immigration policy; then propose a possible policy change and implementation plan using the fifth and sixth steps Jansson’s policy plan respectively (Jansson, 2010). According to Guyette, Tavalin and Rooker (2012), the United States has throughout history attempted to control illegal immigration into the country by passing restrictive policies and increasing border security. These approaches have failed if the debate for and against illegal immigrants is anything to go by. Data concerning illegal immigration is mostly hypothetical, since transactions concerning immigrants are mostly not recorded in any official documents. For instance, Barnes (2010) claims that it costs each native households $ 1,117 per annum to support illegal immigrants, totaling to $113 billion a year for the whole nation. The influx of illegal immigration cases can be blamed on a myriad of reasons, but the main cause is the government’s inefficiency in enforcing its policies on immigration. Therefore, the country needs to refrain from a complete overhaul of policies, which has been the main reason for increased illegal immigration due to inefficiency and inconsistencies, and adopt a stable policy that will be monitored and improved continuously. Any policy proposal change should ensure to account for all the positive and negative aspects of immigration, mostly by being fair to illegal immigrants if the merits of having them in the country outweigh the demerits. An effective policy should contribute positively to various aspects of the United
