...Non-Ionizing Radiation at UNITEN (ICNIR 2003) Electromagnetic Fields and Our Health 20th – October 2003 22nd Recent Research on Mobile Phones Effects Dr. Abdullah AlOrainy Inst. of Electronics Research, KACST P. O. Box: 230471, Riyadh 11321, Saudi Arabia E-mail: alorainy@kacst.edu.sa ABSTRACT The use of mobile phones always accompanied by the issue of health implications for human. Previous research studies show no evidence of the impacts of mobile phones to human health. New studies suggest that mobile radiation might double the risk of developing cancer on the side of the head used, increase brain activity, can cause damage to nerves around ears and, more importantly, damages the BBB. Also new research shows that biological effects are possible without any warming of tissues which impose of the current radiation exposure levels. KEYWORDS Mobile Radiation, Health Effects INTRODUCTION There are now about 1 Billion mobile phones in use worldwide, and it is expected to reach 1.6B lines by year 2005. In many countries, penetration rates of more than %50 has been reached. At present, there are approximately 4.5 million GSM subscribers in Saudi Arabia and STC has commissioned Ericsson and Nokia to expand its GSM network to 5.5 million lines (~ %20 penetration rate). This wide use of mobile technology have often raise the question about if there are health implications for human. In fact, there are conflicting reports relating to possible health effects from mobile phones and base...

...relationship between brain disease and cell phone radiation has been a current issue. Whether or not the radio frequency cell phones put out can lead to brain bombardment of any type such as brain tumors, brain disease, etc. There have been many case studies, experiments, and the use of high levels of technology to be able to determine the answers to such a controversial issue. Through the explanation of different levels radiation and what radiowave/frequency the cell phones emits, the scientific effect of the radiation on the brain, and lastly through the research to answer the question of whether or not this could be a cause of brain disease to occur. Though there is a lot of supporting evidence that has been found on this topic, I do not believe that cell phone radiation can lead to brain disease. Mobile devices emit very small levels of radiation, though there are many different types of radiation: Electromagnetic radiation, x-rays, and gamma rays. These different forms radiation has been found electromagnetic radiation linking to some cancers (Leikind). Where as theses types of radiation can have a negative impact on the body and become very dangerous over time. Radiation can break covalent bonds in ones body (Lekind). When using a cell phone though one is allowing the electromagnetic fields to constantly bombard the body but not to the levels of harm. Electromagnetic radiation adds to molecules or atoms, in which then the radiation transfers its energy into atoms and molecules...

...Research Review on the Biological Effect of Cell Phone Radiation on Human 1, 2 Ashraf A. Aly1, Safaai Bin Deris2, Nazar Zaki3 Faculty of Computer Science and Information Systems, Universiti Teknologi Malaysia 3 College of Information Technology, UAE University, UAE Ashraf.ahmed@uaeu.ac.ae, safaai@utm.my, nzaki@uaeu.ac.ae increased incidence rate of traffic accidents due to the use of mobile phone while driving. The risk of exposure to electromagnetic field was first highlighted and publicized in the late 1970s by Colorado study [2] that linked magnetic field exposure from power lines to the possible development of child leukemia. The amount of RF generated by cell phone is usually depends on the number of base stations around the area, the cell phone network traffic, and on how far the cell phone from base stations. The amount of the power which sent from a base station could vary from cell phone to another one even within the same area, depends on the interfering from obstacles such as buildings and trees [3]. Although, cell phones are designed to operate at power levels below a threshold for known thermal effects, radio frequency radiation could produce other kinds of effects, called biological effects. In Figure 1, we show a calculation of specific absorbed radiation (SAR) distribution in an anatomical model of human head positioned next to a 125 mW dipole antenna. The resulted Peak SAR is 9.5 W/kg over 1 mg which is a clear indication of the effect. Abstract The growth in...

...cell phone use by adults, human exposure to electromagnetic radiation is happening in ways never dreamed of before. Very young children are using them, teenagers live on them—and some even sleep with them on their pillows, as cell phones are often used as alarm clocks. What do these exposures consist of and what do they mean for human health? Whether cell phone use affects the human nervous system and reproduction, causes DNA damage and behavioral changes, or creates addictive behavior, cell phones are now ubiquitous in our lives. Cell phone technology has changed quickly over time and continues to develop, which means that human exposures also change over time. This report explores what we know about cell phone use, exposures, and human health. Impact of mobile phone technology in environment: The Cell Phone Problem Electromagnetic Radiation _ All cell phones emit a type of radiation called an electromagnetic field (EMF), composed of waves of electric and magnetic energy moving together through space. Different types of electromagnetic energy are categorized by their wavelengths and frequencies and comprise the electromagnetic “spectrum” (see next page). _ Different radiation frequencies are used by different technologies. Radio waves and microwaves emitted by transmitting antennas are a form of electromagnetic energy collectively referred to as radiofrequency (RF) energy or radiation. _ The RF part of the electromagnetic spectrum consists of frequencies in the range...

...to have stringent Electromagnetic Frequency Radiation Standards. epartment of Telecommunication (DoT) is all set to implement the new policy and regulation on electromagnetic radiation emitted by Mobile Tower and Handsets from today i.e. September 1. The policy is to made in corcern for the safety issues over health hazards due to radiations emitting from Mobile Tower and Mobile phones. With the implementation of these norms Indian standards would now be 10 times more stringent than more than 90% countries in the world. From September 1st 2012, for all mobile towers that must reduce emission to one-tenth of the present limits else face penalties of Rs 5 lakh per tower. While for Mobile handsets manufactured and sold in India or Imported from any other countries should be checked for compliance of Specific Absorption Limit. No handsets of SAR value above the prescribed standard adopted in India should be manufactured or sold in the country. Department of Telecommunications has recommended that the radiation level per cell tower should be less than 1-watt per sq metre-reducing it to 1/10th the current permissible norm. All research points out to the impact on the human immune and nervous systems, complications in reproductive health as well as behavioural problems in children. He emphasised that all epidemiological studies point out to adverse impact of mobile radio especially on children, pregnant women and on male fertility. radiation has two effects-thermal and non-thermal...

...The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. All types of electromagnetic radiation are transverse waves and they all travel at the same speed in a vacuum. The regions of the electromagnetic spectrum are explained below in order of increasing wavelength and decreasing frequency. Gamma Rays (γ-rays) Gamma rays have the lowest wavelength but the highest frequency in the electromagnetic spectrum. They are produced by radioactive atoms in nuclear explosions. Gamma rays are highly penetrating rays and can kill living cells, which due to this it is used in medicine to kill cancerous cells. However, they can also kill healthy cells which could lead to cancer. Gamma rays are also used to kill bacteria in food and to sterilise surgical instruments. X-rays X-rays are used to produce photographs of bones to check if for any damages or fractures. They can also be used to check metal components and welds or any other damage. The earths atmosphere is too thick for x-rays to enter, so x-ray astronomy has to be done in space. X-rays come from fast electrons that decelerate after striking something. Advantages of x-rays are they can be used to check if anyone has any broken bones in their body. Disadvantages are that x-rays can cause mutations in the DNA, they can cause cancer and they...

...Impact of Cell Phone’s Radio Frequency in Children Herzing University Saugat Basnet The development and use of mobile device services in the last decade have hugely increased the amount of radiofrequency electromagnetic wave (RF-EMW). High exposures towards radio frequency (RF) in our daily lives have raised concerns regarding the harmful effects on human health especially on children. Children with cell phone exposure have higher odds of migraines and headache-related symptoms than the one with no exposure. A great deal of scientific and public interest have focused on radio frequencies that alter the brain, somatic and germinal cells in children. Children should be very careful and guided by elders while using cell phones that produce a lot of harmful radio frequencies. Today cell phone is one of the inseparable parts of modern life. Each and every daily activity today is possibly accomplished by the aid of the cell phone. With its reference, we can say that cell phone directly and regularly comes in contact with the vital body parts like head and sense organs. As it comes in contact with vital organs, not immediately but after some long term exposure, it causes severe health problems and in children, it’s even more serious. Children are still developing mentally; therefore, radio frequency from cell phones has a greater effect on them than on adults. It is because children have growing body parts where cell multiplication is active. According to a study conducted by Sudan...

...understand how potentially harmful cell phones are society must consider the many people using them. There are three billion cell phone users worldwide and more than 260 million in the United States alone (Mead 422). It is shocking that so many people around the world and U.S are cell phone users and they all may not know how harmful cell phones can be. It is important to discover how this technology of cell phones was created and developed in order to look into how it is affecting humans. In 1974, in response to growing demand for a communication system that was more convenient than two- way radios, the Federal Communications Commission (FCC) allocated a portion of the radio frequency spectrum in the 800 to 900 Megahertz (MHz) band for mobile communications (Barnes 120). This was the beginning of cellular technology. As time and technology progressed cell phone technology developers wanted to improve the quality of communication. The newer form of communication is between the frequencies of 1850 and 1990 MHz (Barnes 120). The most...

...phones correlates with the instance of brain tumors. This paper will analyze the findings of these studies and provide a description of the findings from the research studies that have been done related to the question do cell phones cause an increase in brain tumors to the cell phone users. Literature Review Berg, G., Spallek, J., Schüz, J., Schlehofer, B., Böhler, E., Schlaefer, K., et al. (2007) found that exposure to radio frequency and microwave electromagnetic fields can contribute to an increase the incidence of brain tumors. The same kind of radio frequency and microwave electromagnetic fields are produced by cell phone phones. If Radio frequency and microwave electromagnetic fields are both produced by cell phones than this could be an issue to anyone who uses a cell phone. If exposure to these radio frequencies and or microwave electromagnetic waves increases the risk of developing brain tumors this is a problem for the majority of the USAGE OF CELLPHONES AND BRAIN TUMORS population worldwide at an estimated “number of cell phone users in 2014 will reach 1.75 billion.” eMarketer (2014). Wiart, J., Wake, K., Vrijheid, M., Villegas, R., Vecchia, P., Taki, M., et al. (2011) suggest that through using spacial maximum specific energy absorption technology they can clearly see that radio frequency and electromagnetic waves that are being transferred into the human brain after using a cell phone. This paper will examine the research...

...Cell Phones Do Not Cause Brain Cancer Abstract The effects of cellular phone use were examined with the attempt to find a correlation between increased brain cancer and increased cell phone use. Over the last 20 years, cellular phone use has become the primary form, and in many cases the only form, of communication. These devices use radio frequency technology to transmit and receive communications. There has been controversy around whether or not these radio frequency signals cause cancers in the brain when the devices are used and placed directly on the head. Multiple studies have not been able to prove a direct correlation between the use of cellular phones and brain cancer. Keywords: cellular phones, cancer, brain, radio frequency Cellular Phones Do Not Cause Brain Cancer Cellular phones became widely popular in the early 1990’s and have become a mainstream necessity to most people today. Many people now use cellular phones as their primary or only form of communication with most households abandoning traditional landline telephony. Technology has also evolved at such a tremendous pace that the majority now uses cellular devices as not only phones, but as computers as well. With the increased demand and the ability for manufacturers to reduce costs, these devices have also become more accessible and important to people of all ages, with the majority of users “in the age range of 18 to 49” (Anderson, 2015). As of 2014, “it is estimated that there are almost...

...International Telecommunication Union reported that there were 6.8 billion mobile phone users in 2013. The leading countries were China, India and the USA respectively. However, in recent years, there have been increasing reports on the health risks that users of cell phones are exposed to. The danger can be avoided if necessary measures are taken. The aim of this essay is to evaluate these health risks. Increases risk of poor vision Staring at the phone over a long period leads to poor vision among users due to exposure to blue-violet light that it produces. Also, the screens of these devices are usually smaller compared to those of computers; hence, users are more likely to strain and squint their eyes while reading messages or scrolling the phone’s features. Users using cell phone application features such as internet, Whatsapp, Twitter, Facebook and Instagram are at a high risk of acquiring eye problems due to prolonged periods of use. Brain damage According to recent research, long-term use of cell phones may lead to brain damage. This is because of extended exposure to electromagnetic radiation, which is absorbed by the brain tissue hence leading to acute brain damage. An individual suffering from brain damage usually has headache and poor memory. Use of earphones for receiving calls and listening to music on the device has also increased the risk of absorbing electromagnetic radiations, further causing damage to the internal part of the ear leading to deafness...
