EMF Radiation From Power Lines - What You Need To Know

The heat on earth is produced by electromagnetic rays striking the earth and the atmosphere, right? Electromagnetic rays are part of the spectrum that also contain X-rays, ultraviolet, etc. We know lead stops the penetration of X-rays, but can the lead also stop the electromagnetic rays? Common sense tells me that the lead will still heat up from regular sunlight. You've got it backwards, X-rays, ultraviolet, visible light, radio waves, etc. It is the electromagnetic spectrum. Whether there are frequency ranges to which lead is transparent, I can't say, but I wouldn't be surprised.

The Electromagnetic Spectrum: Ionizing Radiation

Radiations from radioactive materials can be dangerous and pose health hazards. By knowing the ability of the different types of radiation to penetrate matter allows us to gain an understanding on how best to protect ourselves. Alpha particles can be absorbed by a thin sheet of paper or by a few centimetres of air. As alpha particles travel through air they collide with nitrogen and oxygen molecules. With each collision they lose some of their energy in ionising the air molecule until eventually they give up all of their energy and are absorbed.

Three types of ionising radiation are:. It has a large mass, compared to other ionising radiations, and a strong positive charge. It has a very small mass and a negative charge. Gamma rays are caused by changes within the nucleus.
