Do Objects below zero degrees Celsius still transmit very small amounts of longwave radiation?
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.
Do humans give off radiation?
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.
Why is radiation so strong?
Radiation can be strong because it consists of high-energy particles or waves that can penetrate and interact with matter, leading to various effects such as ionization or damage to cells. The strength of radiation is determined by factors such as the type of radiation, the energy level of the particles or waves, and the dose received.
Which type of radiation can only be stopped by a thick lead sheet or very thick concrete?
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.
Why can heat travel through space by radiation?
Heat can travel through space by radiation because it is a form of electromagnetic energy that does not require a medium to propagate. Objects with a higher temperature emit infrared radiation, which can transfer heat energy over large distances in the vacuum of space.

What is in the electromagnetic spectrum?
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.

What cancers can radiation cure?
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.
What type of radiation does radium give off?
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.
What astronomical objects are best studied with radio techniques?
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.
Can chemical radiation give you super powers?
No, but it will probably make you very sick and decrease your life expectancy greatly.
Does the iPod give of radiation?
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 .
Why are brown dwarfs hard to detect?
They are hard to spot because they give out very little energy. Most of their radiation is in the infra-red.
