Basically, the higher the half-time, the lower the effects on human health. The radiation pollution is the increase of the amount of radiation in the environment, The sources of radiation pollution are natural sources and artificial sources, Natural sources are represented by natural radioactive materials found on the Earth’s surface (the radioactive elements) and the cosmic radiation that comes from the outer space. Natural sources Naturally occurring particulate matter (PM) includes dust from the earth’s surface (crustal material), sea salt in coastal areas and biologi-cal material, in the form of pollen, spores or plant and animal debris [1]. The physical pollution of the atmosphere is a consequence energy input like sound and heat energy. Coal also possesses small amounts of radioactive material in the likes of uranium and thorium. Radioactive Pollution: Causes, Effects and Solutions to Nuclear Radiation. Conventional thought led us to believe that such is the huge expense of the seas that surround us that irrespective of what we drop in the oceans, it will be such an insignificant bit that it will not be enough to generate any serious concerns. Radiation is the emission of particle or energy in wave form. Cosmic rays possess high energy ionizing electromagnetic radiation. With alpha radiation, a living thing will need to be within centimeters of the radiation source to be affected by the radiation. Natural Sources of Radiation– Natural sources are those which are exposed or occur in the environment naturally from the earth or other outer sources. However, it is very hazardous. The aim of this study is to propose a new hazard index based on nitrogen input and its connection with nitrate concentration in groundwater. 03 May 2016. The mutagenic effects of radiation were first recognized in the 1920s, and since that time radiation has been used as an important means in genetic research to obtain new mutations in experimental organisms. Sources of air pollution Sources of air pollution [1] include natural sources [2] and human-made sources [3]. One of the greatest problems of modern times is the sound or noise pollution. Annex B: Exposures from natural radiation sources.
