General Facts About Radioactive Wastes Essay

1520 words - 6 pages

How can nuclear waste be managed for better future?Radiations are used in many part of the world, in the field of therapy for removing tumors and cancer, used as weapons, produced in industries…etc. Recently, people had been discussed a lot about the nuclear energy which seems to be the best possible solution to solve the ever worsening energy crisis. But despite of all the advantages of using nuclear energy, the major drawback, the release of radiation, still cause people from supporting the use of nuclear energy.Radiation is the energy releases while the decay of some radioactive isotope’s neutron which are not stable. These energies are released in different forms, which are further classified into Alpha and Beta particles, Gamma rays and neutron radiation. 2type of radiationpenetrates…blocks by…characteristicsAlpha radiationthe skinsheet of paperharmful to lungsBeta radiationinto the bodysheet of aluminum foilGamma raysgo through bodyseveral cm of lead or concrete, or meter of waterneutron radiationgo through the bodymeters of concretethe most powerful among all3The radiations can also be found in the nature, these are called background radiation since soil holds radioactive substances such as uranium, thorium, radium and the radioactive gas radon which is continually escaping to the atmosphere; these-------------------------------------------------------------------------------------------------------footnote:1,2,3 : http://www.world-nuclear.org/education/wast.htmradiations are usually considered not harmful since the concentrations are too low. After the radioactive substances gone through the decay process which releases mostof its energy, the remains of it are normally still harmful and these are called radioactive waste, or radwastes, which can be classified into 3 categories: low level waste, intermediate waste, and high level waste.4type of radwastessources of disposalcomprise of ways of disposallow level wastehospitals, laboratory, industries, and nuclear fuel cyclepaper, rags, tools, clothing, filtersburied in shallow landfill sitesintermediate wastereactor decommissioningresins, chemical sludges and reactor components, as well as contaminated materialssolidified in concrete or bitumen or buried in soil and the dept is depend on its time it remain hazardoushigh level wastenuclear reactors, nuclear power plantsused fuel itself and principled waste from reprocessing the fuelVitrification and seal properly in order to store underground.5-------------------------------------------------------------------------------------------------------Footnote:4: http://www.world-nuclear.org/education/wast.htm5: http://www.epa.gov/rpdweb00/docs/radwaste/402-k-94-001-snf_hlw.htmlhttp://www.epa.gov/rpdweb00/docs/radwaste/402-k-94-001-tru.htmlhttp://www.epa.gov/rpdweb00/docs/radwaste/402-k-94-001-llw.htmlThe waste can also be classified by their life span.

Radioactive Waste Essay

1414 words - 6 pages Radioactive waste is defined as “any material that contains a concentration of radioactive nuclides greater than those deemed safe and for which no use is foreseen” ["Press Kit: Radioactive Waste Management."]. Radioactive wastes produced in every step of the nuclear power cycle and are the leftovers from the use of nuclear materials for nuclear power generation, medicine, agriculture, research, industry, and education and other such purposes

Radioactive Waste Essay

1769 words - 8 pages humans and from the environment. HLW takes about a million years to completely decay and it has such high level of radioactivity that the waste also generates heat. There are many problems with HLW, the most important one being that it is very hard to fulfill the requirements of storing radioactive waste. The requirements being that the waste has to be stored for a very long time, they have to be stored in well-designed storages, and the

Long-lived radioactive waste decays at a much slower rate than short-lived waste, and therefore retains its radioactivity longer. The opposite is true for short-lived wastes. Radioactive waste can also be categorized as low-level or high-level, according to the amount of radiation given off.Low level radioactive

Elements released need to be kept away from the environment and humans since it causes a lot of harm (Caravelli, 2011). It is not a good idea for countries in the Middle East to develop nuclear energy. One of the critical reasons that make this a bad idea is the fact that nuclear energy causes damage to the
