Environmental economics article review Environmental economics article review. The review of journal of environmental protection, 2014 on measurements of fission products from the Fukushima Daiichi incident in San Francisco Bay area Air Filters, Automobile filters , rain water and food. The article is from scirp.
The Fukushima Daiichi incident has been given a close monitoring since its occurrence in the 1980s. This has been done more so by the Berkley National Laboratory whose major interest is analysis of the gamma emitters. More concern has been given to analyzing lead and beryllium. Research process is done keenly in search of any isotopes that may have leaked or fallen out to the environment. This was done by monitoring their presence in automobile filters. Furthermore, it is checked using rain water which may contain the isotopes. It has been a great worry to most researchers, scientists and writers at large. Therefore thorough checking in all possible components in the environment that can be contaminated is analyzed. Food is one such an area of major concern to these interested parties (Smith1 et al, 2014).
Analysis of the samples suspected to contain heavy metals and isotopes is done using spectroscopy techniques. During analysis of the dangerous rays and substances, safety measures are taken into account to avoid accidents. For instance, shielding against cosmic rays is done.
Air sampling is carried out using an air sampler to assist in determination of gamma emitting fission products from the site of occurrence. This is done with high efficiency while observing safety. Filter exchange is also done after a period of about twenty four hours. First findings indicated that Half-life of Iodine isotopes were 8 days for that with atomic number 131 and for that with atomic number of 132 took 2.3 hours. These findings were essential for establishment of a sample gamma spectrum that could give a good visual representation of findings.
However, that alone is not sufficient and other sources of samples have to be considered. Therefore automobile air filters come into play. Priority is given to analysis of sample deemed to release radio isotopes that have the capability to harm or affect people. The technique aims at measuring airborne contamination degree (Smith1 et al, 2014). Samples up to about one thousand two hundreds are used to ascertain the level of available radio isotopes. They are estimated using an odometer or through monitoring of fuel consumption of the vehicles. Screening helps the researchers to get alerts of any possible contaminants. This sets the area apart and gives a hint of how and where to proceed with the evaluation and analysis.
Rain water measurement is very essential. This is because it gives a report and acts as an indicator for presence of radio isotopes. This is done more so in areas near the Fukushima Daachi accident sites. The samples are collected in beakers and analyzed spectroscopically. However, most of these isotopes were prone to faster decay hence may not give an authentic picture or indication of real scenario. Other alternative sources of samples are therefore important. Such include soil, sediment samples, food measurement and Chernobyl comparison methods. All these have proved very useful as far as environmental assessment, management and economics are concerned (Smith1 et al, 2014).
In conclusion, the article addresses the environmental problem caused by the Fukushima Daachi incident that may have long term economic effects to the world. I chose this article because It captures how to assess the degree of impact caused by the released radio isotopes that affects environmental processes and influence the economic policies. This is an important issue because it has affects many counties, yet only a few people clearly understand it. I felt that the article is precisely up-to-date and strongly recommend that other people read it, especially my colleagues in this course given that it builds references to both the environment and economic issues.

Environmental Article Critique

...? Article Critique: Environmental studies Introduction of the Article The following is a critique of “Performance tools and their impact on pollution reduction: An assessment of environmental taxation and R&D, “ published in the International Review of Public Administration, 15(3), 53-53 by Im, Tobin I., and Wonhyuk W. Cho in 2011. The research was motivated by the fact that in spite theoretical implications of environmental taxation coupled with governmental participations in research and development, there has never been sufficient link between the effects of such aspects within environmental context and improved performance especially through empirical...

Environmental/Occupational Health solve the problem if determined necessary. The manufacturing firm had not said they would take no action. There is no reason for the researcher to be concerned at this point. It is not the researchers’ responsibility to communicate results in advance of the completion of the project. Kass, 2001 1778 2 3 34 – 37 47 - 50 Risk management communications can be tricky with unforeseen reactions from the public and the media. In the case of Shell and the UK government, Greenpeace used the power of the media to stop a viable, environmentally sound deep sea disposal of the Brent Spar oil storage platform. If a company and a government cannot communicate a clean-up that was handled properly, without a negative media reaction,...

International Economics many professions, for example in secretarial, and some customer services areas like call centers, and even in highly skilled professions like radiology and accountancy. The effect of this will be to relocate many millions of jobs away from richer countries and towards poorer countries like India which has an educated, English speaking workforce with lower wage costs. Binder recommends that America should resist the temptation to engage in protectionist activities, because these shifts are inevitable, but to promote instead workforce flexibility, aids to transition towards personal and local services, and better safety nets for displaced workers. The current transformational initiative of US economic reform is...

Current Event Review 4

...Current Event Review Europe Bans Airport Body Scanners For "Health and Safety" Concerns The article “Europe Bans Airport Body Scanners For "Health and Safety" Concerns” by DiSalvo (2011) published in the Forbes, reports about the banning of X-ray body scanners in each and every European airport. This has been enforced by the Commission of European Union. Studies have revealed that X-ray body scanners which employ “backscatter” ionized emission technology are lethal enough to spoil DNA and possibly result in cancer, thereby causing a gross violation of Business Ethics with reference to health and safety. As an alternative, European airports will make use of less harmful millimeter-wave scanners. I believe this is...

... US President Obama and Fiscal Cliff US President Obama has declared in his first news conference, subsequent to victory after re-elections, in his call for high salaried persons in the US to reimburse additional money in excise and taxations in his first news conference since winning re-election. He ordered for rapid proceedings to chalk out tax increase on the initial $250,000 (£158,000) of earnings, but rejected to elevate tax rates for the richest to 2%. The year of 2012 serves as "fiscal cliff" for US by cost-cuts and taxes mounting. The year of fiscal cliff will also observe that George W Bush-period tax cuts ended up in amalgamation of repeated, across-the-panel decrease in armed forces and household spending. Loophole...

... National Geography: Approaching Food Shortage The article by Charles Siebert gives an introduction about the approaching crisis relating to food shortage. A statement is given about the rising population growth rate, and this is expected to cause major troubles in feeding it. The only best solution is to produce twice as it used to be, but then another challenge in this is that the crop yields are increasing slowly, and the invasion of crop diseases and the unpredictable climate change impacts negatively. Fortunately, there are some seeds still left and the only conservative step to take to ensure they are kept safe. The second part mentions about a farm six miles away from the town of Decorah in Iowa. The farm is about 890-acre... National...
