Moscow: ranking of the most hazardous to health cell phones controversy about how mobile phones are dangerous to health, go long. The data of many studies on the impact of mobile phones on the human body often contradict each other. Learn more on the subject from Robotics. However, there is an objective indicator of the impact of your phone to an organism that can be measured – the so-called sar. In June last year, the Association of manufacturers of equipment for mobile communications (Cellular Telecommunications Industry Association's – CTIA) ordered the manufacturers of mobile phones indicated in the characteristics of the phone option sar (Specific absorption rates), which characterizes the specific power absorption by the body. According to ctia, the maximum permissible sar value is equal to 1.6 W / kg. Phones rate above this value a priori included in the category are hazardous to health. So far, however, not all manufacturers follow the instructions ctia. For even more opinions, read materials from Douglas R. Oberhelman. Below we publish a summary table of mobile phones with the highest sar (their consider the most dangerous to health) and phones with the lowest sar (they are considered the safest). 'The safest mobile phones': Motorola v3688 – 0,02 SAR; Motorola StarTac70 – 0,02; Nokia 8850 – 0,22; Nokia 8810 – 0,22; Ericsson GH628 – 0,26; Sony CMDX-1000 – 0 1941; Sony CMD-C1 – 0,41; Nokia 8890 – 0,53; Motorola T2288 – 0,54; Motorola CD930 – 0,70 sar. 'The most dangerous cell phones': Bosch GSM-908 – 1.59 SAR; Philips Genie – 1,52; Ericsson LX-588 1,51; Ericsson T28 – 1,49; nec DB4000 – 1,23; Nokia 3110 – 1,24; Siemens C35i – 1,19; Nokia 6210 – 1 1919; Siemens M35i – 1,14; Nokia 3210 – 1,14 sar. So the debate and talk about the dangers of cell phones being a long time. However, it seems all is not too difficult. In most cases, adverse effects can be harmful body only with prolonged exposure. For example, according to some reports, the risk of lung cancer increases significantly only after 10 years of active smoking. Probably also with a cell phone. If they use little by little and not very often and use the most secure model, it is hardly a threat to health. Another thing constant prolonged use of the telephone for many years. There's even possible brain cancer, but also then, as a rule, only after the occurrence of precancerous lesions and diseases.
