Radiation can be defined as energy that is transmitted in the form of rays, waves or particles. Human body is exposed to various types of radiation. Some are harmful to our body, whereas others are not. Electromagnetic radiation is emitted by cell phones for the purpose of communication.
Effects of Cell Phone Radiation on Human Body
The amount of emissions made by cell phones is quite minimal. Our body is exposed to cell phone radiation while making or receiving calls. The radio waves given out by the mobile handsets are absorbed by the human body. This type of radiation has a mild heating effect on the living tissues in the body. It is likely that this rise in temperature does not cause any damage to the cells, per se.
However, there are indications that cell phone radiation can cause a few changes in the functioning of cells. These changes are mostly temporary in nature. The functions that get affected by radiation include activation of proteins, communication between the body cells, genetic functions etc. Though the exact reasons behind these changes have not yet been ascertained, it has been confirmed that they are not caused by heating of the tissues.
Impact on the Blood-brain Barrier
The blood-brain barrier present in the central nervous system is responsible for restricting the passage of unwanted substances between the blood stream and the neural tissue. As the term suggests, the function of the blood brain barrier is to block or prevent certain harmful substances from entering the brain or the spinal cord, while allowing useful substances, like oxygen, in. Radio waves radiated from cell...
