Such thing as iPhone 4S radiation level is an important point in addition to smartphone's CPU frequency, memory and megapixels in the camera. Usually the characteristics is measured in SAR - a "level of radiation determines the energy of the electromagnetic field, liberated in the tissues of the body in one second." During the period after the Samsung Galaxy S III was carried out dozens of benchmarks and tests, in which the Android-smartphone compared to the iPhone 4S, including specifications, the voice features and strength of construction. But a comparison of Apple's and Samsung flagship handsets of this kind we find on the web for the first time. Israeli creator of the jailbreak application Tawkon, which measures radiation of iOS-devices, has published a new study, according to which the radiation level iPhone 4S is three times higher than the Galaxy S III. According to the developer, the rate of the SAR's top handset is 0.34 W/kg for the iPhone 4S radiation level is 1,11 W/kg. The effect of electromagnetic radiation is much controversy. Some argue that it can cause quite considerable damage to human health. Others, on the other hand, argue that the radiation of mobile devices does not exceed certain standards, virtually harmless to human body. Which of the of the assumptions to trust is up to you you decide. U.S. Federal Communications Commission  (FCC) and the regulatory authorities of some other countries have adopted the rate equal to SAR 1.6 W/kg when calculated per 1 g of body tissues. In the European Union the adopted norm of SAR is 2 W/kg for 10g of tissue. The another thing that can't be proven is the long-term influence of different types of radiation on our body. No one can say for sure what changes will iPhone radiation or other smartphone waves or even Wi-Fi waves do with our body. I'm not talking about superpowes or things like this and we'll see that only in 50-70 years.
