Mobile Impact

Have you heard the news that mobile phones can cause brain cancer? Although the above has not been proven true, but it is true that mobile phones emit radiation, a big.

U.S. FCC Agency has been testing the level of radiation which is emitted a few mobile phone. Strength of mobile phone radiation Received labeled brain or SAR (Specific Absorption Rate) measured in units of watts / kg. The FCC stipulates that all mobile phones which emit radiation above 1.6 watts / kg is prohibited to be produced (banned in the U.S.).

Virtually all mobile phones can still afloat is considered a "safe" because of its SAR level is still below the 1.6 watts / kg. Org Nevertheless there are some who feel a bit dizzy or hot ears after using a cell phone handhone who is considered a "safe" is. So who really safe (not just a safe course) is a distinguished level of radiation below 1 watt / kg.

Therefore to separate distinguished "safe" and who "really safe", was made the data below. Here SAR data released by the United Kingdom National Physical Laboratory and the U.S. FCC agency (Federal Communication Commission)

HANDPHONE WITH EXTERNAL ANTENNA
(antenna radiation leads to the brain)
In this type of mobile antenna position just beside the brain, so that the greatest risk of brain cancer.
For example: Bosch 908/909, All mobile phones & Sony Ericsson, Nokia 5110/6110/6150, Siemens S25/C25/C35, Motorola T2688, P7689.

HANDPHONE WITH DESIGN-SHELL Clam (fold)
(antenna radiation leads to the jaw)
Because of the folds, then the mobile phone of this type of antenna positions are next to rampang.
By positioning the antenna away from the brain, the risk of brain cancer at such handhone smallest.
For example: V3688/V8088/StarTac Motorola, Samsung A100, Samsung SGH800

HANDPHONE WITH INTERNAL ANTENNA
(antenna radiation leads to the ear)
In tsb mobile antenna position beside the ear, so the risk of brain cancer is not too big. But the side effects that cause ear heat faster.
For example: Nokia 3210/3310/8210/8850, Siemens S35/M35

From the above explanation about the effect of antenna position against the emission of radiation to the brain, it can be found the reason why Motorola StarTac V and has the lowest degree to which the SAR.

It also found the reason why when using the Nokia 8210 quickly ears felt hot. This is because the Nokia 8210 uses an internal antenna so that radiation leads to the ear.

Nokia 8210 mobile phone itself, although quite high but tingakt radiated SAR is not too high (only slightly above 1 watt / kg). This is because with an internal antenna, antenna position a little bit far from the brain. This is different from Nokia 5110, Genie Philips, Siemens C25, Ericsson T28, and GF768 distinguished clearly position the antenna in addition to our brain. Ear heat which of course our brains are better distinguished drpd heat.

The low level of mobile phone radiation is also something to do with cell phone signal strength. The assumption was that big semakian radiation, then the stronger the signal. Nokia 8810 which radiation is very low (0:22 watt / kg) may also cause weakness of this mobile phone signal. This is different with the Motorola V which SAR levels are low, but strangely stronger signal. This is disebakan because radiation from Motorola V is actually very large, yahitu almost 1.6 watts / kg (close to the threshold of danger FCC). But because of the placement position of the antenna away from the brain (in addition to our jaw), then finally received brain radiation which we finally very low.

Dr. Paolo Rossini of Fatebenefratelli hospital in Milan, Italy, and colleagues used Transcranial Magnetic Stimulation (TMS) to examine brain function while using cell phones. In this study Paolo had 15 young male volunteers use a GSM 900 cell phone for 45 minutes. As a result, the motor cortex cells of 12 of the 15 volunteers, adjacent to the cell phone showed excitability during phone use but returned to normal after one hour later. The cortex is the outermost layer of the brain, the motor cortex is known as the "excitable area" because magnetic stimulation resulting in muscle strain.
In fact, medical studies about the use of mobile phones and their effects on the brain have provided mixed results. Last year Swedish researchers found the use of mobile phones in the long term will increase the risk of brain tumors. However, a study by Japan's four mobile phone operators who have not found evidence that radio waves from mobile phones can harm cells or DNA.

The same Dutch Health Council analyzed several studies and found no evidence that radiation from mobile phones harmful to the brain. Everything is still all the controversy. However, it would be prudent to mobile phone users to put forward the caution and not excessive. Use the phone as needed.
