Why are gamma rays and x-rays harmful to human beings?

Question

Why is UV radiation only a little bit harmful and radio waves not harmful at all?

Answer 1

High-energy electromagnetic radiation (gamma rays, x-rays, and short UV) are called ionizing radiation. It is dangerous because it has enough energy to break atomic bonds. In small doses, it can damage cellular DNA, leading to reproductive problems or cancer. In high doses it can do enough damage to destroy tissue and cause prompt death.

Since the body absorbs all electromagnetic radiation to some degree, any part of the EM spectrum can be dangerous at high enough intensity. For example, water is opaque to microwaves and infrared, so they are efficient means of transmitting heat to your body - too much and you'll be burned. Long-term exposure to radio waves is also associated with some health problems - cataracts for example.

Answer 4

Because of how powerful they are. Radio waves are very weak and have a wavelength which doesn't harm the human body.

UV is harmful because it can screw up the cells it hits if they're exposed for large amounts of time.

Gamma rays and x-rays are dangerous because they're energy levels are SO HIGH in fact it takes a chunk of concrete 3 feet thick to stop a gamma ray, and you still get an x-ray popping out of the back of the thing.
They hurt cells by damaging the DNA, Gamma rays shoot therough the body and when they hit a DNA strand they don't stop they just cut right through it.

Answer 6

Molecules (groups of atoms) are held together by electrons. Those bonds have a certain amount of strength, depending on which atoms and so on. X-rays and gamma rays happen to be about the same strength as those bonds so a photon of x-rays or gamma rays can break the bonds. This causes the molecule to split apart. Instead of having the molecules your body is supposed to have, it has smaller molecules that it isn't supposed to have, which can be very poisonous for a cell. This is why x-rays and gamma rays are called ionizing radiation. They make ions out of melecules.

Answer 7

It is because gamma rays and x rays have smaller wavelengths (higher frequencies) then visible light and radio waves. Ther order in decreasing wavelengths are

Radio Waves
Microwaves
Infrared
Visible Spectrum
Ultra Violet
X Rays
Gamma Rays

Answer 8

Gamma rays I'm pretty sure are harmful, and X-rays can do damage to your reproductive organs, but are ok. Thats why they make you wear the lead bib thing over your belly at the dentist when you get X-rays of your teeth made.
