 “Are Mobile Phones Harmful?”



A mobile phone can store or receive information in the form of sound, text, numbers and images, electronically. Microwave radiation is used to transmit signals (mobile phone calls and texts). Communications, through the use of mobile phones, are essential to modern-day life. Mobile phones use microwave radiation to send signals back and forth to a nearby phone mast. We will discuss whether the use of mobile phones poses a health risk (are harmful), or not.

“Are Mobile Phones Harmful?” – Against

Mobile phones are an essential tool in today’s life. There are many benefits that mobile phones bring in today’s day and age; faster communication, they are fun (children and adult alike) and they enable us to carry out our tasks quicker. Humans communicate to one another using mobile phones. Out of the electromagnetic spectrum of the different radiation types, microwaves and radio waves are the most suitable and most appropriate types of radiation that are and can be used, to use a mobile phone as the radiations are not absorbed by the atmosphere.  

There have been a variety of criticisms against mobile phones, such as, they have a heating effect or they cause brain cancer. Multiple studies have been carried out to date, but none have found a direct correlation between the use of mobile phones and any cases of brain cancer developing. The World Health Organisation states that:

“To date, no adverse health effects have been established for mobile phone use.”

As such, no case on adverse health effects have been reported, neither has there been a case or cases where mobile phones are creating health risks.

 “Are Mobile Phones Harmful?”- For

Mobile phones are indeed a very useful tool when communicating to other people locally, nationally or world-wide. However, as science is ever more showing clearer understanding in the objects we use, there are a variety of health risks that mobile phones may pose towards humans, which should be regarded with paramount importance and explored deeper.

Firstly, if we take for example microwave ovens also use microwave radiation to transfer energy to absorbing materials. Microwave radiation, once absorbed, allows the molecules in the material to vibrate strongly- the temperature of the material rises. Mobile phones also use microwave radiation to receive and transmit calls and texts to nearby phone masts. The greatest intensity of radiation is as it leaves the mobile phone. Thick bones in your skull which surrounds and protects the brain absorb this radiation. Even though the bones absorb the radiation, it still effects and is absorbed by the brain, which warms it very slightly.

Now from one perspective this may seem perfectly harmless as the brain is heated ‘very slightly’. However, if a person uses a mobile very frequently, and that is extremely common in the present-day, then the heating effect could be disastrous and would be a serious health risk.

    Visible light is so common that molecules that are ionized by it will often react spontaneously, unless protected by materials that block the visible spectrum; examples include photographic film and some molecules involved in photosynthesis. Ionizing radiation has a wide range practical uses, but it is also dangerous to human health.
