Cell Phone Radiation Essay

Decent Essays
Since the introduction of the cellphone to the technological world has occurred, more and more people around the world have been keeping their devices close to their heart. People are constantly using their device to do multiple activities a days, whether it is using it for simply calling or texting a friend or family member, browsing the internet to stay connected to the rest of the world, or entertaining you by allowing you to watch videos or play high graphic games. Whatever the use, cell phones have come in handy in almost every situation we confront in life. However, there is concern that the over usage of cell phones may increase the chance of obtaining cancer over a person’s lifetime. The constant radiation emitted from the device …show more content…
The goal of this article is to shed some light on this issue and to assuage people’s fear of cell phone radiation causing cancer. Like stated before, the article is against people abandoning their cellular device due to cancer risks, because so far, there is simply not enough evidence that it does indeed cause cancer (Loria, 2016). The article references an experimental study conducted by the US National Toxicology Program. The research question of the experiment was whether or not excessive device radiation on rats can significantly raise their chances of obtaining cancer compared to rats that are not exposed to radiation. Therefore, for this study, the independent variables were the two groups of rats: those that were exposed to full body radiation for nine hours a day from birth to about two years of age, and the control group where rats were not exposed to cell phone radiation from birth to two years of age. The dependent variable is the chance of developing brain cancer due to exposure to radiation or not. The population that is being tested in this experiment is the entire rat population, where rats were randomly obtained to be used in the study. The sampling strategy is not specified by the article but is most likely a random sample of rats to be used …show more content…
This test was utilized to determine if the two sets of data, rats that underwent radiation and rats that did not, were significantly different from each other. Also, both the populations’ mean and population variance was unknown for the experiment, which implies that an Independent Student’s T test must be used. The first step of NHST is to state the null and alternate hypothesis and decide on whether or not he experiment is one tailed or two tailed. A one tail test was used for this experiment because it was testing if an exposure increased the likelihood of obtaining cancer. If it were a two tailed test, then the experiment would only test to see if there was a difference in the likelihood of getting cancer or not, whether it be an increase or a decrease. After establishing if the test is one tailed or two tailed, a null and alternate hypothesis must be stated. The null hypothesis states that there is no difference in the means of the two groups, where the mean of group one is less than or equal to the mean of group two and any difference is due to chance. The alternate hypothesis makes the test exhaustive and states that the mean of group two is greater than the mean of group one. Group two will be made the rats that are tested under radiation for nine hours every day until they reach the age of two. The next step of NHST is to set the criterion. Setting the criterion involves

    A scientific claim made about cell phones is whether or not radiofrequency energy exposure possibly causes cancer or other negative health risks or effects. 4 Cell phones emit an electromagnetic, non-ionizing form of radiation as radiofrequency energy from their antennas. This energy can be absorbed by nearby tissue such as your ear. Electromagnetic non-ionizing radiation is low energy and low frequency.…

    Being on the cell phone for hours can call brain damages, and that’s call microwave radiation. Cell phones may force people to be anti-social, lose patience easily, and use incorrect spelling. It limits our face- to- face interactions with one another. “Cell phones have caused a big issue with spelling and grammar” (Ira Hyman Ph. D, 2014). A positive impact that cell phones have on today’s society is the ability to contact family and friends in case of an emergency.…

    However, the majority of the people had no information about the radiation exposure they received constantly from cell phones. Many of the people surveyed had no clear idea of what harm they were exposed to, or about the level of radiation they were receiving. The research found does not completely support the idea of dependency and addiction to cell phones. It is a surprising discovery because from the photograph that was taken (see Fig. 15) what people say is contradicted.…

    In fact, a recent study conducted by Danish researchers has ended health scares that linked to cell phones. The Danish researchers conclude that cell phones are not dangerous as well as the researchers strongly believe illnesses such as cancer and/or a brain tumor do not come from cell phones. According to the Institute of Cancer Epidemiology, “A study comparing cancer incidence rates over the past 30 years had conclusively proven that cell phone users do not face a higher risk of cancer” (“Danish Scientists Dismiss cell phone health risks”). This proven study could mean that the evidence is correct, in which cell phones are harmless. Although, there is a possibility that the study is incorrect and the rates do not match up which means, the facts are inconclusive.…

    I have a hard time saying either way whether cell phones can cause cancer. My dilemma comes from my mother’s personal experience with cell phones and cancer, and the information presented in a few of the articles refuting the idea of cell phones causing cancer. My mother’s experience stems from working the radiology department at my local hometown hospital. She has seen and heard about a few cases of young women developing cancer where they keep their phone. Because she is employed at the hospital she receives articles that lean towards the idea of cell phones causing cancer.…

    From what i read, and from my research i believe that cellular phones do not cause in any form any sort of cancer. Such as brain cancer, breast cancer, eye cancer, and any sort it doesn’t show that it causes cancer. People that have said phones cause cancer is from early 2000s and is not recent in any form. My evidence is that if you were to use your phone for 25 years and up you have 0% chance of getting any type of cancer it doesn’t increase any type of cancer.…

    Many people are concerned about the dangers that cell phones pose, and they are told that keeping it a greater distance from their heads and using devices such as headphones can diminish much of the radiation; all of which is true. Unfortunately, since the technology industry has made the invention of wireless headphones, if people use their cell phones in conjunction with these devices, the radiation dosage can be even greater than normal. Using Bluetooth, the main type of wireless communication between devices, can have just as much electromagnetic radiation as talking on the phone. One team realized this and began to test the power density rating and the specific absorption rate (SAR), both of which measure radiation dosages. This team…
