Cell Phones Informative Speech

I'm here talking about how cell phones can give girls cancer and how guys can hurt their sperm count by using cell phones But first, I talk about that cell phones work by sending signals and receiving them from nearby cell towers using Radio Frequency waves this is a form of electromagnetic energy that falls between FM radio waves and microwaves. At very high levels, Radio Frequency waves can heat up body tissue. That's how a microwave oven works. The levels of energy given off by cell phones are much lower, and are not enough to raise temperatures in the body different cell phones have different SAR levels. The SAR levels are different depending on the apple Apple iPhone 6 plus give off 1.16 SAR levels and apple 4s gives 1.19 SAR but the

The city of Berkeley passed a law that goes into the effect of cell phones. (Hill) So people are talking about how the RF waves have like a little microwave in the cell phones so they give off a little bit of radiation in the cell phones because the more you use the cell phone the more radiation you can have and when it happens to little kids because their tissue in their brain are very thin in which they can get brain tumors when using a cell phones. (Hill) He found that about 50 percent of the 326 studies showed a biological effect when the radio-frequency radiation but people found the the wireless industry he found the split was 70 - 30. (Hill) Lab studies usually expose animals to something like RF energy to see if it causes tumors or other health problems. (American Cancer Society) Researchers might also expose normal cells in a lab dish to RF energy to see if it causes the types of changes that are seen in cancer cells. (American Cancer Society) A large study now being done by the US National Toxicology Program should help address some of the questions about whether exposure to RF energy could lead to health issues. Researchers will expose large groups of lab mice and rats to RF energy for several hours a day for up to 2 years and follow (observe) the animals from birth to old

Since 2011 evidence has been brought from Jonathan M. samet, the chairman of preventive medicine at the University of the Southern California who found the panel that determined the classification many studies have failed to detect an association between cell phones and brain tumors. (Storrs) One study of 360,000 adults in Denmark have not yet been found for those with brain tumor and people who have been using a cell phones for 13 years have not have not been caught with a brain tumor. (Storrs) Some professors say that 1,640 hours some people in their lifetime without a head set have a better chance to not get brain tumor. However authors of the Interphone study stated that people with brain tumors might be more likely than healthy people to exaggerate their cell phone use, and thus the link between heavy phone use and brain tumor risk in the study might not be real. (Storrs) The Interphone study is the largest study to date looking at cell phones and brain tumors. It involves 13 countries, including Canada, the United Kingdom, Denmark and Japan. (Hill) Researchers asked more than 7,000 people who had been diagnosed with a brain tumor and 14,000 healthy people about their previous cell phone use. (Schipper) So what have researchers learned about cell phones. In one study they followed more than 420,000 cellphone users over a 20-year period, researchers found no
