Cell phone Radiation

Cell phone radiation is the process in which energy from a cellular is emitted as particles or waves. Cell phone(wireless or mobile) devices are one of the world biggest communication devices in the 20th century. About half the adult population own smartphones, 2020 80% will own smartphones.. Cell phone radiation is a interest of study with its radiation effects on humans and global consequences for agriculture, government, and financial services.

Over time the number of telecommunications, the usage of phones, the calls per day, and length of call has increased. According to the the International Telecommunication Union, globally, cell phone subscriptions is estimated to be 5 billion. More are effected by the radiofrequency energy, a form of electromagnetic energy. The electromagnetic energy can be categorized in two forms; ionizing radiation(e.g radon, x-ray, cosmic rays) and non-ionizing(e.g radio-frequency and extremely low-frequency or power frequency, radar and microwave ovens). The exposure of ionizing radiation is a high risk of cancer. More consistent evidence cancer caused by types of electromagnetic energy, causing from ionizing-radiation rather than non-ionizing radiation.. The most known biological effect of radiofrequency is heating, as the ability of microwave and ovens to heat food, is an example of this effect of radiofrequency energy. Radiofrequency exposure from cell phone use does cause heating; however, it is not sufficient to measurably increase body temperature.The use of cell phones for 50 minutes, brain tissues from the same side as the phone's antenna metabolized more glucose than did tissues on the opposite side of the brain.

Measurement of Exposure

The levels of the exposure of radiofrequency is indirectly estimated using questionnaires or interviews, including:

• How regularly study participants use cell phones (the minimum number of calls per week or month)
• The age and the year when study participants first used a cell phone and the age and the year of last use (allows calculation of the duration of use and time since the start of use)
• The average number of cell phone calls per day, week, or month (frequency)
• The average length of a typical cell phone call
• The total hours of lifetime use, calculated from the length of typical call times, the frequency of use, and the duration of use

Possible Cancer Causes

The radiofrequency energy from cell phones held closely to the head effects the brain and tissues, yet no evidence from studies of animals, cells, or human that radiofrequency energy can causes cancer. Many studies such as; case-control study, cohort study, and interphone study has been conducted to determine if cell phone cause cancer. Case-control study, cell phone use is compared between people with these types of tumors and people without them. Cohort study, was a large group of people is followed over time and the rate of these tumors in people who did and didn’t use cell phones is compared. These studies have generally not provided clear evidence of cell phones and cancer. Interphone study conducted by a consortium of researchers from 13 countries, which is a health related case-control study of use of cell phones and head and neck tumors. Most published analyses from this study have shown no statistically significant increases in brain or central nervous system cancers related to higher amounts of cell phone use. One recent analysis showed a statistically significant, albeit modest, increase in the risk of glioma among the small proportion of study participants who spent the most total time on cell phone calls. However, the researchers considered this finding inconclusive because they felt that the amount of use reported by some respondents was unlikely and because the participants who reported lower levels of use appeared to have a slightly reduced risk of brain cancer compared with people who did not use cell phones regularly. The prospective Million Women Study in the United Kingdom found that self-reported cell phone use was not associated with an increased risk of glioma, meningioma, or non-central nervous system tumors. The researchers did find that the use of cell phones for more than 5 years was associated with an increased risk of acoustic neuroma, and that the risk of acoustic neuroma increased with increasing duration of cell phone use.

The finding from different studies of cell phone use and cancer risk has been inconsistant. Reason of this is:

• Inaccurate reporting, is when which may happen when one's say that something has happened more or less often than it actually did. Many may not remember how much they used cell phones in a given time period.
• Recall Bias, is which may happen when a study collects data about prior habits and exposures using questionnaires administered after disease has been diagnosed in some of the study participants. It is possible that study participants who have brain tumors may remember their cell phone use differently than individuals without brain tumors. Many epidemiological studies of cell phone use and brain cancer risk lack verifiable data about the total amount of cell phone use over time. In addition, many who develop a brain tumor may have a tendency to recall using their cell phone mostly on the same side of their head where the tumor was found, regardless of whether they actually used their phone on that side of their head a lot or only a little.
• Paticipation bias which can happen when people who are diagnosed with brain tumors are more likely than healthy people (known as controls) to enroll in a research study. Also, controls who did not or rarely used cell phones were less likely to participate in the Interphone study than controls who used cell phones regularly. For example, the Interphone study reported participation rates of 78 percent for meningioma patients (range 56–92 percent for the individual studies), 64 percent for the glioma patients (range 36–92 percent), and 53 percent for control subjects (range 42–74 percent).

Effect

As cell phones provide a efficient way to communicate with friends, family, and co-workers, excessive use can take a toll on your health. Cell phones use transmitting waves series of base station where radofrequency waves are electromagnetic fields that can not break chemical bonds or cause ionization in human bodyEven though cell phones are low-powered radiofrequency transmitters, the handset transmit power when its on, therefore it is significant to keep distance to reduce radiofrequency exposure. Federal Communications Commission (FCC) suggests cell phones users to keep a minimum distance of 20 centimeters from handset to reduce exposure of radiation. Short term effects is tissue heating, which is the principal mechanism of interaction between radiofrequency energy and the human body. At the frequencies used by mobile phones, most of the energy is absorbed by the skin and other superficial tissues, resulting in negligible temperature rise in the brain or any other organs of the body. A number of studies have investigated the effects of radiofrequency fields on brain electrical activity, cognitive function, sleep, heart rate and blood pressure in volunteers. Long term effects is the relationship or association between brain tumors (cancer) and phone use. However, because many cancers are not detectable until many years after the interactions that led to the tumor, and since mobile phones were not widely used until the early 1990s, epidemiological studies at present can only assess those cancers that become evident within shorter time periods. However, results of animal studies consistently show no increased cancer risk for long-term exposure to radiofrequency fields.

Feedback

When you add this work you're creating to the mobile phone radiation and health make sure that you don't duplicate any of the existing information in the article - you need to carefully integrate your additions into what's there already.

When it comes to any medically-related claims, please bear in mind is that the standards for citations for these is higher than the general standard for sources in Wikipedia articles. Focus more on review articles and less on the latest discoveries. While we always encourage the use of secondary and tertiary sources in general, this is especially important in medical-related topics. Check out the brochure I've linked to for more information.

And one more thing - regarding that image: did you actually create it yourself? An image search shows dozens of different versions of that image online; unless you were directly involved in the research that produced that scan, it's unlikely that actually are the creator of that image.
