The present article concerns about concepts, comments on the composition, working method, advantages and disadvantages of using the CCD, and its application in remote sensing as well, and to do so, we discuss the physical principies of the remote sensing, electromagnetic spectrum, propagation of the electromagnetic radiation, interactions between energy and atmosphere, atmospheric windows and the information acquisition system (detection, record and storage).

In the previous two decades, there has been a rapid and remarkable development in the field of communication technologies to encompass many joints of social life, especially devices for daily use, from mobile phones to laptops, to microwave transmitting and receiving towers, in addition to electromagnetic induction furnaces. This puts us in the fact that we are currently inside a multi-spectrum electromagnetic cloud. In this research, the effect of exposure to electromagnetic radiation and checking the negative side effects on the human body was studied through the use of remote sensing techniques, an electromagnetic radiation intensity measuring device for some devices circulating daily with humans, i.e. mobile phones, to assess the effect of this radiation emitted on human health. The study adopts elementary standards to determine the value of the radioactive energy and its effect on human organs after taking samples from cell phones. In addition, the results show that the effects of radiation depend on depends on the time of exposure.

The three-fourth surface of the earth is covered with ocean. The study of the ocean is important for sustainable overall development of a nation and world at large in view of it being rich in resources and playing a crucial role in the climate of the region and changes associated with it. The space-based observations assume significance, as it provides synoptic and repetitive coverage of the ocean in contrast to the sparse and isolated in-situ buoy or ship observations. The remote sensing of the ocean with the help of satellite or satellite oceanography has many other applications also. The electromagnetic radiation in the visible, near infrared, thermal infrared, and microwave regions are used by the sensors on-board space platforms to measure the diverse physical, biological, and geological parameters of the ocean. Amongst the various electromagnetic regions, the microwave region plays an important role in the study of the ocean.

With the rapid development of modern science and technology, remote sensing geological survey theory based on what is built on the interaction mechanism the physics of electromagnetic radiation and geological body. It is through the multi-wave spectrum (light), more than reality, multi-imaging, multi-polarization, multi-level enhancement processing technical means to collect and analyze remote sensing data in order to get more spectral, space geological information than alteration mapping. Remote sensing geological survey does not require direct contact with the target, but use of visible light, infrared, microwave detection instrument, through photography or scanning mode, the induction of electromagnetic radiation energy, transmission and processing, thereby identifying the surface target from a long-range, high-altitude and even outer space platforms.
