∙ 14y agoAluminum is used as a "beam hardener" in medical X-ray machines. It blocks low energy ("soft") X-rays but allows high energy ("hard") X-rays to pass through. That might be what you're thinking of. The reason this is a good thing is that soft X-rays don't have enough penetrating power to get through much body tissue anyway, so allowing them to strike the body increases the total amount of radiation the patient is exposed to without providing any additional information in the resulting image.

What form of electromagnetic waves can pass through metal?
X-rays and gamma rays, although metals do absorb some of both.
What metals reflect radiation from a nuclear bomb?
Other than the light, heat, and UV radiation (which can be reflected by most metals) from a nuclear bomb, nothing can reflect the radiation.The various forms of nuclear radiation are absorbed not reflected:alpha radiation is completely absorbed by one ordinary sheet of paper, no metal is neededbeta radiation can be absorbed by most metals very efficientlygamma radiation is poorly absorbed and can pass through many feet of even very dense metals like lead and uraniumneutron radiation is poorly absorbed and can pass through many feet of even very dense metals like lead
How are nanotubes being used in water purification?
Since the nanotubes are very small, only some molecules can fit through them. Water is able to pass through, but the impurities in water like bacteria, metals, and viruses will not fit through. Therefore, the water will be purified through nanotubes.
What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
What is the only ocean which the equator does not pass through?
It does not pass through the Arctic Ocean or the Antarctic Ocean, so there are actually two it does not pass through.
What allows xrays to pass through?
radiolucent allows x-ray pass through radiopaque does not allow it to pass through
Can gamma rays and xrays pass through the human body?
Yes.
Can heat and electricity pass through metals?
Yes, heat and electricity can pass through metals.
What materials allow heat to pass through and electricity?
metals have the ability to pass and conduct electricity and heat through them....
What is the name of the metals that allow electricity to pass through?
Conductors.
What a material that current can pass through easily?
Metals mainly. Iron copper water these are things electricity can pass through
What material that current can pass through easily?
Metals mainly. Iron copper water these are things electricity can pass through
Do xrays get through earths atmosphere?
no.
What can electric current pass easily through?
good conductors like metals
Can xrays be stoped by bone?
Yes, that's why it is used to tell where bones are. The x-rays pass through the tissues like muscles and fat but are stopped by the bones.
What materials allow electricity to pass through them?
All metals for example iron, copper, nickel. They are called conductors. Plastics and other elements do not, only metals. They allow electricity to pass through them because they have free electrons
Can xrays go through body?
Yes.
