Answer:
Explanation:
Technological advances of mankind, through the development of electrical and communication technologies, have resulted in the exposure to artificial electromagnetic fields (EMF). Technological growth is expected to continue; as such, the amount of EMF exposure will continue to increase steadily. In particular, the use-time of smart phones, that have become a necessity for modern people, is steadily increasing. Social concerns and interest in the impact on the cranial nervous system are increased when considering the area where the mobile phone is used. However, before discussing possible effects of radiofrequency-electromagnetic field (RF-EMF) on the human body, several factors must be investigated about the influence of EMFs at the level of research using in vitro or animal models. Scientific studies on the mechanism of biological effects are also required. It has been found that RF-EMF can induce changes in central nervous system nerve cells, including neuronal cell apoptosis, changes in the function of the nerve myelin and ion channels; furthermore, RF-EMF act as a stress source in living creatures. The possible biological effects of RF-EMF exposure have not yet been proven, and there are insufficient data on biological hazards to provide a clear answer to possible health risks. Therefore, it is necessary to study the biological response to RF-EMF in consideration of the comprehensive exposure with regard to the use of various devices by individuals. In this review, we summarize the possible biological effects of RF-EMF exposure.

INTRODUCTION
There is a constant geomagnetic field on the surface of the planet as solar wind generated from the sun meets with the inside of the earth. Therefore, all life on Earth is always living in the presence of an electromagnetic field (EMF) (Hollenbach and Herndon, 2001). With the development of science and technology, artificial electromagnetic waves have been generated on Earth, and the German physicist Heinrich Hertz experimentally discovered electromagnetic radiation and confirmed the existence of the EMF in the ecosystem.
With the progress of science and technology, many electronic devices have been invented and used, therefore, we have easily been exposed to the created artificial electromagnetic waves in our daily life. Especially, explosive use of various electronic devices in modern society has inevitably led to increase continuously the chances of electromagnetic wave exposure. The development of wireless communication technologies, such as computers and smartphones, have become a necessity for modern people. As a consequence, all living things on Earth are experiencing environmental changes and are being exposed to artificial electromagnetic waves which have not been experienced before.
The effect of electromagnetic waves on living creatures has been controversial due to studies with contradicting results. However, in 2011, since the World Health Organization’s International Agency for Research on Cancer (IARC) designated mobile phone RF-EMFs as Group 2B, that is, possibly carcinogenic to humans, the social anxiety about electromagnetic exposure has increased (Baan et al., 2011). Considering the fact that most people, including young children, use mobile phones in Korea, the possibility of exposure to a considerable amount of electromagnetic waves exists all around us, therefore social interest in the impact on RF-EMF exposure has been greatly increased (Langer et al., 2017).
