The results of experimentally determined values of indoor radon, thoron and their progeny concentrations observed in selected 127 dwellings of 47 villages sampled by single entry pin-holes based dosimeters and progeny sensors for one year are summarized in Table 1. The radon concentration varies from 16±0.9 Bqm-3 to 50±23 Bqm-3 with an arithmetic mean of 30±7 Bqm-3 and geometric mean (and geometric standard deviation) of 30 (1.25) Bqm-3, which is less than the lower limit of the action level (200-300 Bqm-3) recommended by International Commission on Radiological Protection [28]. Also, the mean radon concentration is well below the world average value of 40 Bqm-3 [1]. The present results of radon concentration are lower than the action …show more content…
Hence the p-values in both cases are greater than the 0.05, so the test accepts the hypothesis of normality. The SW test is consistent with the standardized skewness and the standardized kurtosis values (Fig. 4). They accept the normality for annual radon and thoron concentrations. In order to determine normality graphically, the output of the normal Q-Q plot was also used (Fig. 5). From Fig. 5, it is clear that the data points are along the diagonal line. Hence, the data are normally distributed.
The equilibrium equivalent radon concentration (EERC) has been found to vary from 7±2 Bqm-3 to 26±1 Bqm-3 with an arithmetic mean of 17±5 Bqm-3 and geometric mean (and geometric standard deviation) of 17 (1.11) Bqm-3. Similarly, the equilibrium equivalent thoron concentration (EETC) has been found to vary from 0.4±0.1 Bqm-3 to 2.6±1 Bqm-3 with an arithmetic mean of 1.3±0.5 Bqm-3 and geometric mean (and geometric standard deviation) of 1.2 (1.46) Bqm-3, respectively. The ICRP [32] has recommended the range of 2 to 50 Bqm-3 for EERC and 0.04 to 2 Bqm-3 for EETC.
The ICRP [32] estimated an expected concentration in buildings, which in terms of EERC is 2 to 50 Bqm-3 and EETC is 0.04 to 2 Bqm-3. All measured values of EERC are found well within the range limit prescribed by ICRP [32]. However, about 6 villages (13%) have a higher value of EETC than the maximum limit given by ICRP [32] and
The risk from radon in water is much lower than the risk from radon in
All the p-values are greater than 0.05, therefore there is a statistical difference between each transect.
Radioactive fallouts will kill as many possibly even more, than the blast itself. Even though it is difficult to prevent the damage that happened as a result of initial blast, it is possible to save human being from being killed by radioactive dusts by building fallout shelter. The fallout shelter that I have created is to protect twelve people from radioactive debris or fallouts. Even though the shelter is my creation, I decided not enter it because I want to save the world’s most skilled people who can contribute better works than me in the re-establishment of new society. This shelter will allow its occupants to stay for 3 months alive because the harmful fallouts will need three months to decay and turn to a safer level. My primary goal is to save the life of prominent people who have the ability of re- establishing humanity. To accomplish this task, I have chosen people who are highly expertise in
Radium appears as a shiny, silvery metal of high radioactivity. Radium can be “used to treat prostate cancer that has spread to the bones,” and in the past, it was “used in luminous paints, for example in clock and watch dials” (Royal Society of Chemistry, 2017). Radium is present in the environment, and people that live in areas where coal or other fuels are burning and released into the air are more exposed to higher levels of radium. Radium can enter the body by breathing or swallowing and can remain in the body for months, only exiting in small amounts by urine and feces (“Public Health Statement for Radium,” 1990). High levels of radium exposure over a long period of time are extremely dangerous to the health of an individual. The harmful effects of radium could cause “anemia, cataracts, fractured teeth, cancer (especially bone cancer), and death” (“Public Health Statement for Radium,” 1990). The greater amount of radium exposure an individual receives, the greater their chance is to developing one of these diseases (“Public Health Statement for Radium,”
The city of Waukesha was “pleased to report” that their water tested negative for everything but Radium and Gross Alpha. Radium is element number 88 on the periodic table and from the name, you can guess that this element is highly radioactive and can be very harmful to the human body. For starters, if radium is ingested and absorbed into the cells and tissues, it can and will start to deteriorate the surrounding tissues. Specifically, radium may cause problems in the immune system including anemia. Radium can cause cataracts and fractured teeth (from breaking down tissue, including bone tissue). High levels of radium have also been known to cause an increased risk in bone, liver, and breast cancers. Gross Alpha is a type of radiation that is released when any naturally occurring radioactive element changes to produce a “decay product”, such as radium. These decay products are formed after billions of years. Alpha radiation is everywhere, in our soil, air, and in our water. This is because or earth’s bedrock consists of varying amounts of radioactive elements. The alpha radiation also varies in our water, due to the water in deep aquifers or wells touching the bedrock; the water may contain the same or less than the same amount of elemental decay. Alpha radiation in drinking / ground water can be in the form of dissolved minerals, or as a gas
Approximately 25% to 33% of the global burden of disease is due to environmental exposures, and environmental conditions are responsible for roughly one fourth of the preventable illness in the world (Clark, 2008, p. 229). There are many factors influencing the health of Copper City’s residents. They are as followed:
Wheaton College is a Protestant affiliated, predominately white, institution of higher education, located in the western Chicago suburb of Wheaton, IL. The liberal arts college was officially established in 1860 by the abolitionist, pastor, Jonathan Blanchard, and named after the founder of the town, Warren L. Wheaton (Betchel, 1984). Wheaton College’s mission was originally dedicated to the values of abolition, temperance, and serving Christ (Betchel, 1984). In modern day, Wheaton has narrowed its mission to focus on serving Christ and “advanc[ing] His Kingdom through excellence in liberal arts and graduate programs” (WHEATON’). Wheaton is still known as a prestigious, Christian college, recognized for its commitment to academics and faith.
It is now known that radium, shown in figure 4, is a potent carcinogen (a substance the cause’s cancer (Wilbraham, Staley, Marta, & Waterman, 2005)). It emits a form of ionizing radiation which “includes electromagnetic radiation (e.g., gamma rays and X-rays) as well as particles (e.g., alpha particles, beta particles, high-speed neutrons, high-speed electrons, high-speed protons, etc.)” (National Library of Medicine, n.d.). Acute studies have been done on the effects of radium exposure on the human body by organizations like the Geneva World Health Organization, the International Agency for Research on Cancer, and Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Man. As a result of their findings, The National Library of Medicine states that sufficient evidence has been provided showing that prolonged exposure to Raduim-224, Radium-226,
The average annual radiation dose received by Americans is 360 millirems (or "mrems"), about 300 of which come from naturally occurring sources like radon. By contrast, you would get only 0.01 mrems per year as a result of living 50 feet from a nuclear power plant. Even a single annual cross-country airplane flight exposes you to 3 mrems, while a medical X-ray gives you a dose of 20 mrems.
This radioactive pollution is anything but acceptable even though it is being deemed “acceptable,” by the Nuclear Regulatory Commission (World Business Academy). The health effects of radioactivity are accumulative in the human body, consequently, the longer an individual has been living around a nuclear power plant, the more radioactivity their body absorbed. Engaged with leading researchers in the field, the Academy commissioned a health study to investigate the potential impact the Diablo Canyon has on the local population (World Business Academy). By examining publicly available health data broken out by zip code, an abrupt trend emerged: the local population in the hot zone has been getting sicker every year the plant has been operating (World Business
Ira Helfand demonstrates ethos, or authority, to argue the fact that any amount of radiation can be detrimental to public health, no matter how small. In order to effectively represent authority with this claim, Helfand uses a report from the National Research BEIR VI, “It is the consensus of the medical and scientific community, summarized in the National Research Council BEIR VII report, that there is no safe level of radiation,” (Helfand, 2012. Para. 2). The National Research Council BEIR VII specializes in the study of nuclear energy. For this group to insist that there is not an amount of exposure to radiation that could be deemed as safe, it is more of an “eye-opener” on the argument. Consequently, including an expert organization’s findings into his article allows Dr. Helfand a security of authority on the
Radon testing is inexpensive, easy and quick, often taking between three and seven days. The best time to test is during the winter, when the home is closed up, but can be done year round.
This gas can be found easily all over the United States in homes, schools, companies,etc. Did you know that the radioactive gas, radon has been found in every state? It is shocking, but still it is true. Therefore I think it would be a smart decision to have mandatory radon testing in schools. It would help us prevent kids from getting lung cancer in schools because of the poisonous gases. There are multiple ways that you can test for radon in a building. But one way would be by calling a qualified radon testers around your area. Many of you may ask, “Is radon a problem in Idaho,” and the answer to that is yes. As the Idaho Department of Health and Welfare state, “... there are many areas throughout Idaho that have high levels of radon.” Such places in Idaho like: Twin Falls with 23% radon, Jerome with 19%, Gooding with 28%,etc. So as we can tell places close to where we live are pretty low, but those percentages can increase over time, that’s only if we don’t take action. Knowing this I believe that we should have testings in schools to make sure that the kids aren’t in danger. This is why I think that it should be mandatory to have radon testings in
The p value is .001, which shows that the data is not normal. However, this test is more reliable with larger sample sizes. Therefore, if there was a larger sample size here, the results of this test may differ from above.
In an effort to address the issue of radio frequency radiation exposure in this community, we will provide a background on the sources of radio frequency radiation as well as the known and suspected health effects. We will also proposed two epidemiological studies and discuss risk management and
