ABSTRACT
Electromagnetic waves generated by different wireless systems like mobile systems, satellite systems, microwave links…etc. facilitates our communications throughout the world. These waves have many effects on the human body as well as our daily lives. The effects of electromagnetic waves cause many problems and diseases in the human body like cancer. Nowadays, types of the cancer caused by these waves has increased, because mobile users have increased. Because of the importance of human, this paper will address ways for humans to reduce the effects of electromagnetic waves and to reduce cancer. The proposal consists of many recommendations in wireless systems like mobile systems, guiding the users of wireless users specially mobile users how to reduce these waves effects. Furthermore, this research will describe methods to decrease electromagnetic waves and propose alternative techniques instead.

INTRODUCTION
It is evident that electromagnetic waves generated by different wireless systems like mobile systems, satellite systems, and microwave systems facilitate communication throughout the world. These waves have many negative effects on the human body, on the environment, as well as on our daily lives. The electromagnetic spectrum (EM) contains an array of electromagnetic waves increasing in frequency from Extremely Low Frequency and Very Low Frequency (ELF/VLF), Radio Frequency (RF) and Microwaves, to Infrared (IR) light, Visible Light, Ultraviolet (UV) light, X-rays, and Gamma rays [1]. Figure 1 is the graphical representation of the spectrum of electromagnetic energy or radiation in ascending frequency (decreasing wavelength). The general nature of the effect is noted for different ranges
Electromagnetic waves have two types of radiation : ionizing radiation and non-ionizing radiation. Ionizing radiation contains sufficient electromagnetic energy to strip atoms and molecules from the tissue and alter chemical reactions in the body. Human beings are constantly exposed to low levels of ionizing radiation from natural sources. This type of radiation is referred to as natural background radiation. The main sources are visible light, ultraviolet light, and infrared light, radioactive materials on the earth’s surface; radioactive gases leaking from the earth, cosmic rays from the outer ionosphere, and natural radio activity in the human body.
Non-ionizing radiation is classified at the lower part of the frequency spectrum with energy levels below that required for effects at the atomic level.
The objectives as outlined in this research after an introduction about the electromagnetic waves types are as follows :
i)Explaining the effects of electromagnetic waves radiation on human.
ii)Methods to reduce electromagnetic wave radiation.
iii)The effect of methods to reduce electromagnetic wave radiation.
iv)Presenting useful recommendations to the cell phone users for reducing effects of the electromagnetic waves radiation.
This research gives useful information not only to the cell phone users, also to other wireless systems users like satellite systems and microwave systems users in order to reduce the effects of electromagnetic wave radiation on human.
