The opinion of an expert
February 5, 2012 8 Comments
I have been able to interview an employee from Option, a global leader in wireless connectivity, security and experience. In the follow paragraphs you can find a summary of his opinion regarding the existence of a relation between brain cancer and cell phone usage.
First of all he mentioned that scientist researching the matter are still not certain about the impacts of cell phone radiation on the human brain. But since they cannot guarantee there are no adverse consequences to the use of a mobile phone, operators, like Vodafone, have made their own limits which are lower than the European regulations. (Side note: The European SAR limit is 2 Watt/kg). This limit is applicable both for mobile phones and the network itself. By doing this the operators want to protect the users and, to be honest, to make sure that no one can blame them in the future if the radiation turns out the be harmful.
One of the major precautions mobile phone manufactures take, is making use of directional antennas. These antennas emit radiation in a certain direction which is oriented away from the head when the mobile phone is used for calling. The design of the mobile phone is made in such a way that the user does not handle a mobile phone conversely. Examples of these are the placement of the speaker and the ease of handling the mobile phone in the correct direction.
Furthermore he stated that the impact of the radiation on the human body is not the same in every body part. The limbs are less affected by radiation while more sensitive regions are the brains, intestines and genitals.
He also stated that the effects of the radiation emitted by the mobile phone are similar to those used in a microwave oven. But since it is still unclear what the (long-term) effects are on the human body unnecessary exposure should be limited. So until a clear conclusion can be made on the effects of the radiation of mobile phones the following things should be avoided:
- Sleeping with your mobile phone under your cushion
- Keeping your mobile phone in your pocked
- Using the mobile phone for long calls
- Using the mobile phone in environments with low reception
He acknowledges the importance of mobile phones these days and that it is very convenient to keep your mobile phone nearby but that since there is still no scientific consensus exposure should be limited. But overall he does not seem to be too concerned since he keeps his mobile phone in a handy holder on its belt.
