Cell Phone Radiation
RF Radiation Dangers?
Are cell phones dangerous to your health? Does the use of cell phones close to one's head can cause illness or disease. Although there is no conclusive proof of these dangers, just about everyone is recommending keeping your cell phone's RF signal away from your body by using an external cell phone antenna or hands-free kit.
Here are a few articles and other sources of information on the possible dangers of cell phone signal.
FDA Cell Phone Info and Health Under the law, FDA does not review the safety of radiation-emitting consumer products such as cell phones and similar wireless devices before they can be sold, as it does with new drugs or medical devices. However, FDA does have the authority to take action if cell phones are shown to emit radio frequency energy (RF) at a level that is hazardous to the user. In such a case, FDA could require cell phone manufacturers to notify users of the health hazard and to repair, replace or recall the phones so that the hazard no longer exists.

The possible connection between cellphones and cancer is controversial. Many years' worth of studies on cellphones and cancer have yielded conflicting results. Currently, there's no consensus about the degree of cancer risk — if any — posed by cellphone use.
The National Cancer Institute (NCI) is the US federal government's principal agency for cancer research and training. The NCI consist of approximately 3,500 employees. They are part of the National Institutes of Health (NIH), one of 11 agencies that make up the Department of Health and Human Services (HHS). The NCI's Mission is to lead, conduct, and support cancer research across the nation to advance scientific knowledge and help all people live longer, healthier lives.
There are three main reasons why people are concerned that cell phones (also known as “wireless” or “mobile” telephones) might have the potential to cause certain types of cancer or other health problems:
- Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation. Tissues nearest to where the phone is held can absorb this energy.
- Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer.
- However, although many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans
- The number of cell phone users has increased rapidly. As of 2010, there were more than 303 million subscribers to cell phone service in the United States, according to the Cellular Telecommunications and Internet Association. This is a nearly threefold increase from the 110 million users in 2000. Globally, the number of cell phone subscriptions is estimated by the International Telecommunications Union to be 5 billion.
- Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. Cell phone technology has also undergone substantial changes.

Effect of RFR on Body Temperature in Rodents - Effect of Cell Phone Radiofrequency Radiation on Body Temperature in Rodents: Pilot Studies of the National Toxicology Program’s Reverberation Chamber Exposure System
Cell phones and other commonly used wireless communication devices transmit information via RFR. At high exposure levels, non-ionizing RFR can produce local thermal effects (tissue heating) that can damage temperature-sensitive biological structures and processes. Given the proximity of cell phone use to the head, there have been specific concerns raised about the possibility that RFR exposure from wireless devices can lead to increased risk of brain cancer. Although the levels of RFR generated by cellular telephones are modest, it is not currently known whether chronic exposure to low-level RFR, not resulting in measurable thermal effects, could impact human health. Therefore, potential increases in the risks of cancer, cognitive dysfunction, and other adverse health outcomes remain a public concern.
Radiofrequency radiation (RFR) causes heating, which can lead to detrimental biological effects. To characterize the effects of RFR exposure on body temperature in relation to animal size and pregnancy, a series of short-term toxicity studies were conducted in a unique RFR exposure system.

Another Study Showing a Cell Phone-Cancer Link Downplayed by the FDA
Mobile phone radiation and health - From Wikipedia, the free encyclopedia
The effect mobile phone radiation has on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world. Mobile phones use electromagnetic radiation in the microwave range, and some researchers believe this may be either harmful or beneficial to human health.
Health Mobile phone cancer study 'flawed' BBC
A study that researchers claim suggests links between using mobile phones and brain tumors is flawed, radiation experts have said. BBC News' Pallab Ghosh reports on the findings The National Radiological Protection Board (NRPB), which advises the government on safety levels, said the study "lacks statistical precision" to draw such conclusions.
You reduce the risk for injuries due to radiation if you direct the antenna straight backwards from your head instead of straight up. Don't carry the mobile phone in the belt around the waist. Avoid exposing the deposits of bone marrow in the hips to the microwaves. Placing the mobile phone next to the heart is now regarded as less dangerous - unless you have a pacemaker.
