Cell Phone Radiation

Communication systems are developing at an incredible speed. This also applies to mobile communication systems, which today are among the most important telecommunication systems operating at microwave frequencies. Working mobile phones are sources of non-ionizing radiation near the head or body. Despite the fact that the average person spends several conversations on a cell phone every day, the issue of the impact of radiation on health has not yet been fully studied. Simulate the effect of cell phone radiation on biological tissues of the human body, in particular on the head. Two computer models of the human head have been built. Computer simulation of the effect of cell phone radiation on biological tissues of the human body has been performed. An important feature of the model is the presence of layers with different parameters. The layers correspond to real biological tissues (skin, adipose tissue, muscle, skull and brain). A study of the field distribution in the volume of the human head, induced by a working mobile phone, is presented. The specific absorption coefficient was determined. Shown is the thermal effect caused by exposure to radiation from a mobile phone. In the case of the multilayer model, lower values of the specific absorption coefficient were obtained, which can be explained by the use of a more accurate computer model. It became possible to graphically represent the propagation of electromagnetic waves through the head model. The temperature distribution over the surface and in the volume of the human head is illustrated.

Cell Phone Radiation

In this research article, an overview is provided of all the plausible effects that cell phone radiation might have on a human body. The number of cell of regular cell phone users has exploded around the world, and cell phones have become an integral part of our lives in the recent past. Therefore, this paper strives to answers public questions regarding the safety of using cell phones. It analyses previous research that has been done in the field to provide concise answers. The article also supports the motion that cell phones can be harmful in the long run; however, there is no conclusive evidence. The future research should be made more streamlined, and focus on human body systems.

This paper presents a microstrip antenna based on metamaterials (MTM). The proposed antenna showed several resonances around the BAN and ISM frequency bands. The antenna showed a suitable gain for short and medium wireless communication systems of about 1 dBi, 1.24 dBi, 1.48 dBi, 2.05 dBi, and 4.11 dBi at 403 MHz, 433 MH, 611 Mz, 912 MHz, and 2.45 GHz, respectively. The antenna was printed using silver nanoparticle ink on a polymer substrate. The antenna size was reduced to 20 × 10 mm2 to suit the different miniaturized wireless biomedical devices. The fabricated prototype was tested experimentally on the human body. The main novelty with this design is its ability to suppress the surface wave from the patch edges, significantly reducing the back radiation toward the human body when used close to it. The antenna was located on the human head to specify the specific absorption rate (SAR). It was found in all cases that the proposed antenna showed low SAR effects on the human body.

In this work, a numerical calculation was carried out in one of the universal programs for automatic electro-dynamic design. The calculation is aimed at obtaining numerical values for specific absorbed power (SAR). It is the SAR value that can be used to determine the effect of the antenna of a wireless device on biological objects; the dipole parameters will be selected for GSM1800. Investigation of the influence of distance to a cell phone on radiation shows that absorbed in the head of a person the effect of electromagnetic radiation on the brain decreases by three times this is a very important result the SAR value has decreased by almost three times it is acceptable results.

Cell Phone Radiation

Enny, in this paper explain that many mobile phone users around the us, but only a portion of the concerned about the dangers of cell phones. This paper was compiled to determine the impact and solutions of cell phone radiation. Mobile phones emit electromagnetic waves which will affect the surrounding environment. Based on existing information, cell phone radiation is thought to cause cancer. Waves emitted from mobile phones over the air is causing electromagnetic radiation. Potential disrubtion of health consequences of radiation electromagnetic field has become an issue which examined till now, so found a variety of health disorders as a result of mobile phone users that includes the impact of mild and severe impact. Experts have discovered some efforts to minimize the effects of cell phone radiation on health of mobile phone users. Every user should know the dangers of mobile phone users. Radiation caused cell phone not only arise when used, but when putting a cell phone in your Pocket can also be exposed to any radiation. Therefore, mobile users need to know how to use a cell phone. Users should pay attention to the level of radiation caused by cell phones, so that the influence of electromagnetic radiation on health can be scaled down for mobile users.

Development Of Language

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.
