nuclear hazards and human health risks

(2014, October 30). Department of Environmental Science Sri Aurobindo College. Operating nuclear reactors contain large amounts of radioactive fission products which, if dispersed, can pose a direct radiation hazard, contaminate soil and vegetation, and be ingested by humans and animals. There are a few other notable benefits: nuclear power plants have the ability to desalinate large quantities of seawater to produce freshwater; nuclear reactors produce cobalt-60, which has many medical uses, such as treating cancer; and nuclear reactors can be used to manufacture hydrogen (Cuttler, 2008). assessment is the process to estimate the nature and probability of adverse health effects in humans who may be exposed to chemicals in contaminated environmental media, now or in the future. Many scientists are of the view that due to body’s ability to repair some of the While many exist in nature, the majority are created in nuclear reactionsa. The safety and health effects of many individual chemical substances are inadequately assessed. 1. Radiation Hazards. Rashad, S. M., & Hammad, F. H. (2000). It is imperative to the health of residents living near power plants that these communities have a detailed, continually updated and tested plan in the event of a nuclear accident. The potential consequence of an accident is high. This can happen if the core cooling system fails, in which case the reactor core and the fu… Eventually, the site will become a green field. Hepatitis B virus . J: With passive systems, no manual activities take place, and no automatic systems have to operate. Human health risk assessment … The claim is misleading; radiation experts and health authorities maintain there is no evidence to suggest that the … The international experts were impressed and moved by the attempts of Japanese health professionals to mitigate the damage caused by the compound disaster – the earthquake, tsunami, and nuclear power plant accident. However, it is important to know that acute radiation syndrome has not been observed in the general population after nuclear accidents. (2016, December 25). Radium, Uranium, Thorium. The fuel of a nuclear power plant undergoes fission to produce the energy that is used to heat water and therefore turn the steam-driven turbine generators. At Three Mile Island, there were no reported cases of ARS (Christodouleas, 2011). The more energy absorbed by cells, the greater the biological damage. An improvement to current protocol may require training local physicians and emergency responders how to safely treat patients exposed to radiation, as this area of medicine is not commonly practiced. For higher risks like fire or tsunami, the risk of failure must be even smaller. Acute radiation syndrome (ARS) may occur when an individual is exposed to more than 1 Gy of radiation (Christodouleas, 2011). Those are two of the highest, but there are many risks. These tragic nuclear accidents are often referenced as a cautionary reminder of the dangers associated with the nuclear power industry. Effects of Environmental Pollution . Human exposure at high enough levels can cause both short-term illness and death and longer-term death by cancer and other diseases. accidents. Therefore, they are typically regarded as a source of “clean” energy. Nuclear power produces low and high-level radioactive waste. formed. So, after 40 years, you either extend it or shut it down. Nuclear power plants are analyzed and protected for every risk you could think of — even including a large aircraft crashing into the building. Microwaves, cell phones, radio transmitters, wireless devices, computers, and other common The alpha particles are fast moving positively charged particles whereas beta particles are high speed It is important for every nuclear plant in the U.S. to analyze these potential consequences, in order to derive plans that combat these specific differences.
