Simply because they emit radiation in the microwave section of the radio spectrum. It's the same type of radiation that cooks your food. It has been proven that prolonged exposure to high levels of radiation have a harmful effect on the body. Remember - when you're using your mobile, you're holding the antenna close to your skin - and the radio waves generated go in all directions... including into your body. Anyone using their mobile for lots of voice calls - should seriously consider a hands-free kit.
Mobile phone masts emit electromagnetic radiation by transmitting radio waves to communicate with mobile phones. This radiation is non-ionizing, meaning it doesn't have enough energy to ionize atoms or molecules in living tissue, thus not causing harm. The radiation is controlled to stay within safety limits set by regulatory bodies to protect human health.
No - for safety reasons, all new phones are shipped with their batteries fully discharged !
To a human being cell phone radiation is harmless. use of a cell phone is equivalent to a nominal amount of time in the sun. A live radio tower however could be extremely dangerous, do not climb over the safety fences or on the tower itself.
Type your answer here... e-safety is about keeping safe using all electronic items such as mobile phones, tv etc.
Profit of mobile phones on human life is the safety of being able to reach someone from anywhere. However, you have the loss of being able to get away from everything, including your phone.
Yes, a Mobile Gamma Ray System emits gamma radiation for various applications such as industrial radiography, medical imaging, and scientific research. Precautions and safety measures must be followed to minimize exposure to radiation.
No,but the safety interlocks can be defeated if tampered with and expose people to microwave radiation. There was a case of a 'short order' chef who partly 'cooked 'his abdomen when the door seals of an old catering model did not seal properly.This is a very rare case. It could be argued that mobile phones expose the head to much greater microwave radiation than an oven.
Electronic devices such as cell phones, microwave ovens, and WiFi routers emit radiation. This radiation can be in the form of electromagnetic fields or radiofrequency waves, and it is important to follow safety guidelines and minimize exposure to them.
pros ad cons of mobile phones Mobile phones are a mixed blessing for many of us. While some of us may miss the days of going out in public without hearing phones ringing all around us, most people do not miss being stranded on the side of the road with no way to call for help.

In normal use, No. Any RF radiation is harmful when it is too powerful. Touching the output connection of a powerful transmitter will cause burns. A lot of study has been done concerning mobile phones and safety to children and people's heads. The final outcome was that no detrimental affect can be detected.
One risk is that mobile phones can have Trojan Horses, which is a type of virus, that extracts pin numbers and passwords. It is also speculated the Bluetooth headsets could be exploited to learn about the data.
