No, all objects above absolute zero give out radiation. However, very hot objects emit more radiation and at higher frequencies than cooler objects.
Yes, objects below zero degrees Celsius can still emit longwave radiation, although at lower levels compared to warmer objects. This radiation, often referred to as infrared radiation, is a natural process where objects release heat in the form of electromagnetic waves.
Yes, humans give off a very small amount of radiation due to the natural radioactive decay of elements within our bodies, such as potassium-40. This radiation is very low in level and not harmful to others.
Radiation is only very strong in some locations. The little locations that give off radiation are un-expected things like Granet counter tops, and your ordinary house microwave. These only give off little radiation. But the only reason it is stronger in other places is because of it's contents. Your body is not used to the fumes that cause radiation. I hope this answer helped you.(:
Gamma radiation can only be stopped by a thick lead sheet or very thick concrete due to its high energy and penetrating ability. Lead and concrete are dense materials that effectively absorb and attenuate gamma rays, reducing their harmful effects on living organisms.
Infrared thermometers can give less accurate readings compared to other types of thermometers, especially when measuring the temperature of objects that are very shiny or reflective. This is because they measure the infrared radiation emitted by an object, which can be affected by its surface properties.

You actually know more about it than you may think! The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays.
Radiation can cure almost all cancers only at their very earlystages when the amount of cancer cells is very small and they have still not entered the blood stream.
Radium emits alpha, beta, and gamma radiation. Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.
No, but it will probably make you very sick and decrease your life expectancy greatly.
Objects that are not extremely cold, or very hot, but warm (by space standards). This is because those objects emit radio waves with fairly high intensity, but not too much higher energy radiation, which would interfere.
Many think that the iPod gives off harmful radiation but that's not true . Research show that the iPod has very little to no radiation at all in fact a mobile phone is almost harmless and the iPod has less than that .
Only if you are very lucky!

They are hard to spot because they give out very little energy. Most of their radiation is in the infra-red.
