Certain wavelengths of light such as infrared, Rays and gamma rays cannot penetrate the Earths Atmosphere. Rays are high energy waves that can penetrate soft tissue, like organs and skin, but not bones and teeth.

If you put a primer on first, it will cover the grain and the stain won't work. Advantages : Ability to penetrate through materials and thus to view things that the visible light can not see.

Disadvantages : Mainly can harm the genetic material in the cells and thus cause diseases especially cancer. Pine is soft, but Iron wood is hard and the pellet may not penetrate it.

.22 CB caps, fired from a pistol, at 20 ft, will bounce OFF a pine 2×4. A high velocity 40 gr .22 LR, fired from a rifle, will penetrate about 1 inch in the same 2×4.

This would give a very underexposed image, which would not be good for evaluating the bone, for example. If you use a regular energy (technique), you will burn out any small foreign body, and we would be unable to see it.

I work in an animal hospital, and if a dog has swallowed a wood item, you may not be able to see it, or just to see a faint outline. I have seen strange things show up on x -rays I have taken, like gum drops and letters on a printed tee shirt.

The factors that effect radiation are: 1) Time 2) Distance 3) Shielding. One of the reasons the operator always stands behind a wall when taking X -rays is to prevent occupational exposure.

The machines and sources are shielded and calibrated (and regularly inspected) to control any random exposures. CIRC, the guns are shielded on the sides, so the beam is very directional.

Sometimes the simplest things turn out to be a demonstration of the wisdom and planning built into the creation. Just being able to see through some objects and not others is a highly complex issue and an incredibly difficult design.

If a material absorbs the waves in the frequencies of visible light, we can ’t see through it, and we say that it is opaque -- like wood. For that reason we can listen to radio or use our cell phones inside our houses.

Clear glass does not have as many electrons with energy levels that absorb visible light. Adding chromium to the glass will cause it to absorb both red and blue energies of light.

The complexity of this system allows us to see those things we need to see, like solid objects that our bodies cannot pass-through. It also allows our vision not to be blocked by things that we canpassthrough, like the air or water.

Most wood, plastic, or non-lead lined ceramic urns canpassthrough the TSA's security screenings. Generally, most airlines will allow you to bring a cremation urn as a carry-on provided it passes through the security screenings.

TSA recommends that consumers purchase a temporary container made of wood, plastic or non-lead lined ceramic for transporting their loved one's remains. Out of respect to the deceased and their family and friends, under no circumstances will an officer open the container even if the passenger requests this be done.

Documentation from the funeral home is not sufficient to carry a crematory container through security and onto a plane without screening. However, we suggest that you purchase a temporary or permanent crematory container made of a lighter weight material such as wood or plastic that can be successfully X-rayed.

Of course things are complicated a bit by the fact that we can't see x-rays using our eyes, and so the x -rays are allowed to fall onto a photographic plate that is sensitive to x -rays. Chemical changes in the plate allow us to see the image.

This makes an X-ray image where the thick parts of bone are the darkest. The pictures show light bones, though, and dark tissue around them.
