Internationally renowned neurosurgeon Prof. Majid Samii maintains that scientific studies have not proved yet that mobile phone radiation has adverse effects on human health.
In the past few years, experts and the public alike have raised concerns over radiation emissions from mobile phones, and conflicting opinions have arisen. With the growing role of cell phones in contemporary lifestyle, the answer still remains elusive.
President Hassan Rouhani responding to the escalating concerns issued a directive “for a thorough appraisal of the issue.” While some international studies indicate health concerns, professionals have not arrived at a consensus.
Prof. Samii, said no conclusive results either on the positive or negative aspects of cell radiation on human health have been reached, reports ISNA.
The deputy of radio wavelength licensing at Iran’s Communications Regulatory Authority (CRA) had earlier said that electromagnetic radiation is classified into two categories: ionizing and non-ionizing radiations. The former comprises radio activated photons capable of causing genetic harm in humans. “Mobile phone radiations are sub categories of radio frequency (RF) waves, and RFs are non-ionizing,” Azim Fard said. Additionally, satellite radiations belong to the non-ionizing category, causing no known adverse health effects, either.
Eyes Susceptible
Mobile phones operate in the high frequency (HF) range of the electromagnetic spectrum, from several hundred MHz to several GHz, to enable wireless phone calls and data transfer, including communication through the Internet. HF fields have the ability to penetrate into the body (the higher the frequency, the lower the depth of penetration), leading to a temperature rise in body tissue. Having a limited capacity to accommodate heat increase, human body has a strong ability to regulate its internal temperature. Therefore, unless above a certain level (referred to as the threshold) depending on the duration of exposure, the human body can dissipate excess heat.
While RFs can have thermal effects on skin, the emitted temperature cannot reach and damage the depth of skin. Eye surface on the other hand, having merely a thin layer is susceptible to adverse thermal effects of RFs.
