Influence of Non-Ionizing Radiation on The Environment, 2013
The paper analyzes the sources of electromagnetic radiation, their intensities and frequency ranges where they are manifested. It also gives the biological effects of electromagnetic fields. At the international level guidelines are given for limiting exposure to time-varying electric, magnetic and electromagnetic fields by the International body for the protection of non-ionizing radiation. It is important to determine whether, in situations of simultaneous exposure to fields of different frequencies, these exposures are additive in their effects.
Title: Non-Ionizing Radiation And Human Health
2020
We receive an unwanted exposure of non-ionizing radiations on a daily basis from variety of consumer products. Common sources of exposure to non-ionizing radiation include mobile phones and towers, dryers, machinery used in hospitals, Photostat, etc. These radiation no doubt are of low magnitude and literally do no cause any side effect simultaneously to their exposure, but their continuous exposure for long times can definitely cause serious health complications not only to the present but also to the future generations.
Scientific review of comparative study on health hazard of nonionizing radiation
TEST ENGINEERING AND MANAGEMENT, 2020
As of late new dangers to people are seen from non-ionizing radiation exuding from different sources like electric electrical cables, GSM media transmission poles and some more. The fundamental point of this paper is to survey the wellbeing risks of non-ionizing radiation exuding from electrical cables and GSM telecom poles on people and think about the consequences of the two, to see which one delivered more impacts on human wellbeing. Introduction of people to radiation from high electric force transmission lines and GSM poles is an incredible worry about people since transmission lines and GSM poles are found wherever in our condition. Every nation has its very own standard for presentation to non-ionizing radiation dependent on rules set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The natural impact of these exposures is a subject of incredible enthusiasm to specialists. A few conceivable outcomes of leukemia have been accounted for alongside other wellbeing impacts, for example, propagation frameworks, variety in glucose substance, neuronal issue, for example, Alzheimer, sorrow and so on. Various papers have been distributed to contemplate the impacts of radiation on individuals, as number of cases have just been enlisted showing the impact of non-ionizing radiation from transmission lines and GSM poles on people. In this paper the two wellsprings of non-ionizing radiations were broke down. Electric electrical cables were found to have more prominent natural consequences for human lives than telecom poles. Keywords: Electric power lines, GSM Telecom Masts, Health hazards and Nonionizing radiation.

Radiation exposure occurs any time that electromagnetic rays or fast-moving particles interacts with living tissue. Ionizing radiation is particularly damaging to tissue; examples include x rays, gamma radiation, and fast-moving subatomic particles such as neutrons. Biological damage caused by exposure to ionizing ranges from mild tissue burns to cancer, genetic damage, and ultimately, death. While radiation in the form of heat, visible light, and even ultraviolet light is essential to life, the word "radiation" is often used to refer only to those emissions which can damage or kill living things. Such harm is specifically attributed to radioactive particles as well as the electromagnetic rays with frequencies higher than visible light (ultraviolet, x-rays, gamma rays). Harmful electromagnetic radiation is also known as ionizing radiation because it strips atoms of one or more of their electrons, leaving highly reactive ions called free radicals which can damage tissue or genetic material. There are, however, potential benefits of controlled exposures to certain kinds of radiation, which can be used for the detection, diagnosis, and treatment of certain diseases.

Radiation standards review concerning non-ionizing radiation
Radioelectronic Systems Conference 2019
This article discusses the aspects related to the use of modern technologies based on electromagnetic non-ionizing radiation, such as the 5G network. Current normative values for safe levels of non-ionizing radiation in Poland, Europe and the United States were presented. The selected 5G network issues have been discussed with the example of acceptable values of non-ionizing radiation and current regulations in Poland were briefly presented. All types of nonionizing radiation and the risk of contact with each of them were also discussed.
Radiation And Its Effect To The Environment
SAMRIDDHI : A Journal of Physical Sciences, Engineering and Technology, 2015
Many forms of "radiation" are encountered in the natural environment and are produced by modern technology. Most of them can give both beneficial and harmful effects. Even sunlight, the most essential radiation of all, can be harmful in large amounts. Most public attention is given to the category of radiation known as "ionizing radiation." This radiation can disrupt atoms, creating positive ions and negative electrons, and cause biological harm. Ionizing radiation includes x-rays, gamma rays, alpha particles, beta particles, neutrons, and the varieties of cosmic rays. Exposure to radiation can cause damage to cells, eventually leading to cancer or other health concerns and also it effects our environment.
Radiation, 2020
Ionizing radiation: is a type of energy released by atoms in the form of electromagnetic waves (gamma rays or Xrays) or particles (alpha and beta particles or neutrons). Gamma radiation (γ): is a type of electromagnetic radiation, and therefore constituted by photons, generally ): is a type of electromagnetic radiation, and therefore constituted by photons, generally produced by radioactive elements or by subatomic processes such as the annihilation of a positron-electron pair. It is also generated in astrophysical phenomena of great violence. Energy of this nature is measured in megaelectronvolts. A MeV corresponds to gamma photons of wavelengths less than 10-11 m or frequencies greater than 1019 Hz. Non-ionizing radiation: They are those whose energy is not able to tear an electron to an atom, in a few words it does not produce ionizations in matter, within it there are two well-known ones.
Effects of Non-Ionizing Radiation and its Health Hazards on human body
Diyala Journal for Pure Science, 2017
The electromagnetic pollution is produced from the electromagnetic radiation source. In recent years, there is electromagnetic pollution in our earth. Different types of source are caused these pollution such as mobile phones, tower lines, and Wi-Fi. The increase of using these devices will lead to increase various problem of public health. The aim of this study was to evaluate the effects of nonionizing radiation and its health hazards on human body. Various data (the power density) were collected from two types of mobile phones, tower cells, photocopy machine, power lines, D-Link wireless and fast link. Data from a school were also collected. Charts and tables of each data were given. It has been found that the increased use in the electromagnetic devices such as mobile phones galaxy and I phone, cell towers, will have extremely negative effect on human health. It has also been found that using mobile phones with the full charge has less intensity than with low charge. It can be concluded from mobile and cell tower data that the exposure limit of RF was lower than the standard RF of Iraq. Further research in a wider level will be required to investigate all type of mobile phones that are used in our city and their effects on human health.

Public exposure to Electromagnetic Radiation, which abbreviatedly known as EMR is a recurring phenomenon and it becomes among the factors contributing to the public concerns. EMR represents a new technology, such as base stations, overhead power lines and other sources of exposure, that is difficult to control by the affected individual. Non-ionizing and ionizing radiation are two major divisions of the electromagnetic spectrum. Both kinds of radiation can be differentiated based on which one has enough energy to knock electrons off atoms upon collision, as well as capable to give out lower-energy harm, such as breaking chemical bonds in molecules. Ionizing radiation is a type of radiation that has a short wavelength to interact with the electrons in biological chemicals. Alpha, beta, and gamma rays are examples of ionizing radiation. The literature on RF effects also focused on the human factor and health parameters, both from the laboratory and epidemiological study perspectives. ...
