1. Cellphone Use Tied to Changes in Brain Activity
2.
Chapter 18: Environmental Hazards and Human Health3. This article deals with a global environmental issue.
4. Researchers from the National Institutes of Health have discovered that less than an hour of cellphone use can speed up brain activity in the area closest to the phone antenna, this new discovery has raised many questions about the effects of cellphones on humans. It is not sure whether the cellphone will have a negative effect on a persons overall health but the radiation emitted from cellphones can be potentially dangerous and alter brain activity. This study is important because it documents that the human brain is sensitive to the electromagnetic radiation that is emitted from cellphones. The biggest question and concern of the researchers is whether or not cellphones will have a long lasting impact because of the constant exposure. It is very hard to determine that but a few observational studies have shown that a link between heavy cellphone use and rare brain tumors exists.
5. I think this is very interesting and something people should be more concerned with since today almost everyone has a cellphone and uses it for hours on a daily basis. If it does have potentially harmful effects we should all be aware of them and try to eliminate tumors or cancer from happening. I think they should try and study the effects of cellphones on children, because today more and more kids have cellphones and since their brains are still developing the radiation might cause more damage to them then to an adult.
6. Dogma- a settled or established opinion, belief, or principle.
