In a research it is been found that mobile phone radiations are responsible for various kinds of health deseases.The radiation which is emitted by the cell phone can cause brain tumors. The radiation can cause a brain tumor on that side of the brain in which side the cell phone is mostly held. A laboratory study proved that the radiation from cell phone harm body cell and damage DNA.Study also shows that more than 10 years of cell phone use cause Glioma. Nickel has been found in most of the mobile sets. More than 30% of UK cell phone user is allergic to Nickel and rash breaks out where the cell comes contacts with the body. The road accident is increasing because of using mobile while driving or sending text messages while driving.
The effect of mobile radiation in human body is now the latest subject of study because of the high increasing rate of mobile phone users around the globe. Mobile phone uses electromagnetic radiation for wireless communication which in some extent is harmful to human body.
A major part of the radiation of the mobile phone is absorbed by the human head. The radio waves emitted by the mobile phone can have peak amplitude of 2 watts. In most system mobile phones scan for the signal after a certain period of time to get the maximum signal from a base station. For this reason mobile radiates after a certain amount of time on a regular basis in different circumstances. The measurement of the absorbed radiation is done by the Specific Absorption Rate’s data for specific mobile data can be found in the manufacturer’s website or any third party website. In Europe the standard for SAR data is 2Watts/kg, averaged over volume of 10 gram of tissue.
Another effect in mobile radiation is dielectric heating, in which it describes that any dielectric material is heated after a regular interval by the polar molecules by the electromagnetic radiation.So, when mobile radiates electromagnetic wave it also heats up the dielectric cells in human body. Most of these kind of heating effect occurs on the surface of the head. The brains blood circulation is capable of disposing the heat by circulating more blood in head. But cornea does not have this similar kind of mechanism.
Researchers from Lund University have found the effect of microwave radiation in rat brain. They found a leakage of albumin by a blood brain barrier which is a thermal effect of electromagnetic radiation.
The Australian Centre for Radiofrequency Bioeffects Research (ACRBR) which said in a statement that
“Until now there have been concerns that mobile phones were causing increases in brain tumors. Interphone is both large and rigorous enough to address this claim, and it has not provided any convincing scientific evidence of an association between mobile phone use and the development of glioma or meningioma. While the study demonstrates some weak evidence of an association with the highest tenth of cumulative call time (but only in those who started mobile phone use most recently), the authors conclude that biases and errors limit the strength of any conclusions in this group. It now seems clear that if there was an effect of mobile phone use on brain tumour risks in adults, this is likely to be too small to be detectable by even a large multinational study of the size of Interphone.”
A study in 2009 described that the radio frequency radiation has a effect response time of human brain. A cell phone with GSM radio frequency radiation was applied to a male subject and it is been observed that the side of the brain which is attached to the mobile has a large or longer response time compared to the other side of the brain which is not attached with the mobile phone.
A number of people who uses cell phone for a long time expressed some feelings before and after the use of cell phone like mental disturbance, fatigue, sleep disturbance, loss of mental attention, headaches, malaise etc.
Another area of radiation is the fixed infrastructure of the mobile technology like base station and their antennas which connect the base station to the mobile and mobile to the base station. Compared to mobile handsets this radiation is more powerful at close quarters. As the distance increases the power of the radiation decreases with the attenuation. Experts in France suggested that the antenna radiation pattern should not be less than 100 meters from a living place.
Telecommunication workers who spent much time closer to the equipments because of testing, installation or maintenance are at higher risk compared to the general population. Many times base stations are not turned off when the workers work near the base station.
A Swedish scientific team have studied and found that mobile phone users who used cell phone for more than 10 years has a high risk of acoustic neuroma,a kind of brain tumor. The increased rate is not found in those who used cell phone for less than 10 years.
A variety of studies was made on the telecom workers from different sector including radar communication, mobile communication etc. and the study came to a conclusion that risk of cancer is more in this persons who were directly attached with the radiation.
In order to protect general human living close to the radiation pattern government and regulatory bodies adopted some safety standards. There are many proposed international and national safety standards but the most respected one is from the International Commission for Non-Ionizing Radiation Protection (ICNIRP).This standard is been adopted by more than 80 countries. There are two standards for safety is available from International Commission for Non-Ionizing Radiation Protection (ICNIRP).One is for normal people and another one is for those who are attached with the telecommunication occupation.
If two or more competitive bodies can share same base station then the extra installation of base station and antennas will be reduced and the radiation will be less. The safety standard for telecommunication radiation in U.S.A. is set by the Federal Communications Commission (FCC).The standards are based on the standards of the Institute of Electrical and Electronics Engineers (IEEE).
