Do you know if your phone is safe?

 

 

How do you rate your mobile phone in terms of radiation emitted? What is the best way to avoid health risks while communicating by phone? These are questions that became more relevant after the warnings from the World Health Organization that the use of mobile phone increases the risk of developing certain cancers.
A wave of fear is widespread, although there have already been some communication to calm the situation, in particular on the reassessment of the need to study not yet published in full and should be released soon in the journal Lancet Oncology , one of most recognized in this area.
The warning was the result of work carried out by a group of 31 scientists from 14 countries for the agency for cancer research from the WHO, whose findings indicate that radiation emitted by mobile phones are "potentially carcinogenic". The same classification is assigned to lead fumes from engines and chloroform, for example.
Underlying the conclusions is that the study shows a growth of 40% in the risk of glioma, a cancer of the central nervous system, including users 'intensive' mobile phones. The participants in the analysis revealed an average of 30 minutes of conversation per day over a period of 10 years. A value that seen in the light of hours users spend on the phone is not even very high ...
According to data from Anacom for the fourth quarter of 2010, the Portuguese users spent 5.3 billion minutes on the phone, making on average 61 calls per month. Each call lasts an average of 2 minutes and 22 seconds. Doing the math that results in an average of two calls per day, totaling nearly five minutes. But these are average figures, and considering that many users have more than one mobile number is easy to realize it's not casual that the number of these extend far 30 minutes.
To complicate the problem, the WHO alert is not associated with any list of hazardous equipment or insurance, and ensure that all manufacturers of their equipment emissions are within safety levels set by international organizations, through the SAR (Specific Absorption Rate) which measures the rate of radiation absorption by the body.
So do the national operators, which contacted by Tek ensure that all equipment is within safety levels and declined to provide a list of the most and least emissions within the current offer.
But maybe not a reason to get fully rested. Compliance with these SAR levels of security is determined on laboratory equipment, should be guaranteed 2W/kg emissions are below the safe limit according to the recommendations of the World Health Organization, which are prior to these new findings .
Board is also information that the SAR level may not be the most relevant measure, as the U.S. regulator warns U.S., the FCC, in a communication on the subject . According to the FCC mobile phones have a built-in power control that reduces emissions to a minimum while maintaining the quality of the call. So information about a SAR value alone does not provide enough information about the amount of exposure to Electromagnetic Fields in normal use, preventing the comparison of models of mobile phones.
Still, the Environmental Working Group (EWG), an American organization profit dedicated to the analysis of issues related to health points out that other studies have already established links between cell phone use and certain cancers, including brain cancer, tumors in the salivary glands and the hearing aid .
Recently a study indicated also a reduction in bone density and mineral content of bones due to mobile phone use on the body . This analysis was performed with a group of men who used the phone stuck in a waist bag.

 

Prolonged use of mobile phones and continued proximity with this equipment are always increased risk factors pointed out by all studies, so some recommendations should be taken as a precaution as part of the advice compiled by some experts:

• Keep the phone away from the body when not in use. Not worth having the device in your pocket, or with himself at the desk when you're working. If you use touches will hear the same messages arrive and the call notices.
• Use the speakerphone feature that allows a lot of equipment already in conversation or refer to ear. Preferably those who already have the wires using Bluetooth also emit radiation.
• If you do not use any of these systems try not holding the phone to your ear and face, keeping it slightly away.
• Choose the messages to voice conversations.
• Avoid calls in places with little sign. The need for tuning the tower increases the radiation emitted.
• Limit the use of mobile phones by children. Some studies have shown that the lower bone density than the skull becomes more "leaky" to radiation.

The Environmental Working Group (EWG) has some of these online advice, which joins the recommendation to purchase equipment with the lowest level of radiation. The organization maintains an online guide for anyone who wants to know what the 10 best and 10 worst level of radiation equipment.
The analysis has been hotly contested - in part because of doubts about the comparison of SAR have mentioned - and also has applicability limits of the Portuguese market models due to differences between the North American market and Europe.
