Quesiton : Why are X-rays and gamma rays able to penetrate the body but radio waves are not?
Answer: Radio waves do not have enough energy but the others do.
Why are X-rays and gamma rays able to penetrate the body but radio waves are not?
Gamma rays visible light and radio waves are all examples of electromagnetic radiation and radio waves are on one end of the spectrum (with a wavelength of meters) gamma rays are on the other end (with a wavelength of about 10-12 meters) and visible light is somewhere in between (with a wavelength of around 5 x 10-7 meters).
How can the answer be improved?
The reason why visible light can't travel through walls as easily as gamma rays or radio waves is because to the visible light there's something 'there' on a similar scale of length (wavelength) and time (frequency) that the gamma rays are too small and fast to interact with and the radio waves are too large and slow to interact with.
Radio Waves to Gamma-rays . Print. ... Infrared radiation is a kind of light wave (usually abbreviated as IR). The same is true of ultraviolet waves (UV) x- rays and gamma - rays . These are all different kinds of light. ... More specifically the earth's atmosphere only allows certain wavelengths of light to penetrate …
So gamma rays are not strongly ‘resonantly’ absorbed by the body and typically they go straight through us (like X-rays). The mechanism by which gamma rays are absorbed is called Compton Scattering and the gamma rays interact with nearly all electrons within an object with equal chance.
Now I would draw the simple conclusion that atleast one part of EM radiation must not be penetrating any metal surface and since EM radiations cannot survive solely as E or M radiation any sort of radiation penetrating metal surface must not be possible. But in fact x-rays do pass metal surfaces.

Example this is the same reason why AM radio stations go farther out than FM radio stations This also the same reason why the bass on speakers goes farther out than the high pitch sounds.
Microwaves do not use x- rays or gamma rays and they do not make food radioactive. Microwave ovens can cook food but they do not otherwise change the chemical or molecular structure of it. Microwave ovens are designed so that the microwaves are contained within the oven itself.
X- rays vs Gamma rays . Gamma rays x- rays visible light and radio waves are all types (forms) of electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of photons which are particles without mass each traveling in a wave-like pattern and moving (circling) at the speed of light. We will examine the x- rays and the gamma rays .
Thu Dec 08 2011 00:00:00 GMT+0530 (IST) · That's why I said in general. There are some materials radio waves don't pass through (e.g. the lined walls of a room with an MRI in it) and if the walls are thick enough radio waves won't pass through them (try using your cell phone inside a cave).
Gamma rays and x- rays consist of high-energy waves that can travel great distances at the speed of light and generally have a great ability to penetrate other materials. For that reason gamma rays (such as from cobalt-60) are often used in medical applications to treat …
In astrophysics gamma rays are conventionally defined as having photon energies above 100 keV and are the subject of gamma ray astronomy while radiation below 100 keV is classified as X- rays and is the subject of X-ray astronomy. This convention stems from the early man-made X- rays which had energies only up to 100 KeV whereas many gamma ...
