Radiation Affecting The Aquatic Environment

Introduction:

Radiation is one of the most threatening events as it affects all life forms including the aquatic ecosystem. One of the most dangerous type of radiation that affects the aquatic life is ultraviolet radiation as the main effect of it is the death of marine plants and animals. That is not the only source of radiation pollution but there are also other kinds of radiation pollution like radioactive materials pollution. Radiation pollution has very serious effects on marine life and general introduction requires to note that for the given criteria for radiation in terms of time (low level constant and high level), radiation risks must be analyzed separately for each geographical area. This is because of the presence or absence of

Nuclear explosions, detonations of nuclear weapons and Defense weapon production: the greatest amounts of human-induced radiation pollution have been generated in the mid twenty century through various experimental or combat nuclear detonations. Mining of radioactive ores (such as phosphate, uranium ores) processing and crushing of radioactive ores and generate radioactive by-products. Nuclear waste handling and disposal: This might produce radiation through over long period of times. Those radioactive sources emit radiation that might debase and propagate through air, water, and soil as well. Thus, their impacts may not be easily distinguishable and are hard to predict. Some nuclear waste location may not be identified. Those fundamental issue with those radiation waste is the way that it cannot degraded or treated chemically or biologically.

2. Effects of Radiation Pollution on Marine Environments After the introduction of radiation types and how they reach the environment, this section will aim to address and assess the effects on marine environments both in Egypt and internationally. 3.1. General Radiation

Because the radioactive chemicals that cause this contamination can enter the environment at any stage of their life cycle from production and usage to disposal. These contaminants can enter the environments through to main entries; point sources and non-point sources. Of course preventing contamination is not less than an impossible mission. Therefore, efforts were pointed to decrease it by closing the easy entries of contamination which are point sources. Good progress has been achieved and the last 10 years were a trial to shift the priority to non-point sources, and trying to take care of it
