Yes, flat monitors are completely safe to use. They tend to give off more heat than the tube monitors, however. But there are no indications that they are not safe to use in a household environment.
All cell phones give off varying degrees of radiation.
Radiation
LCD monitors are a cheap technology that present a pretty decent picture and can achieve a decently high resolution, while LEDs are more expensive with a better picture, and CRTs give off radiation and can't achieve a very high resolution. LCDs are very favorable monitors for their price, and decent picture quality.
All objects give off thermal radiation.
Yes, fire gives off radiation in the form of heat and light.
Yes - infrared radiation. If you're asking about nuclear radiation, then no.
Yes, the Earth does give off radiation in the form of heat. This radiation is primarily in the form of thermal infrared radiation emitted by the Earth's surface in response to solar energy absorbed during the day.
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
No, fans do not give off radiation. Fans simply move air around to create a cooling effect by increasing air circulation. They do not emit any harmful radiation.
A 'ray' is a term for a radiation. All objects with temperatures above 0 degrees Kelvin give off radiation called, "Heat".
