Answer 1

And what kind of name is blackjesuz7!?

Answer 2

it is photographic film , Geiger tubes ionization chamber.

Answer 3

Lead is the best material.

Answer 4

x-ray will be stopped if u block it with material that can attenuate its energy

in radiation protection, lead is the common shielding material used

the higher the x-ray energy, the thicker lead sheet needed to absorb/attenuate its energy

Answer 5

The x-rays would stop by the element with higher density. The reason is that electrons can stop x-rays and so the element should have max. possible no. of electrons in min. area and thus density will be more. The best options are uranium, mercury, etc.

Answer 6

X-rays are, as we all know Electro - Magnetic waves.

But there is one important fact that is needed to be understood.

Electrons can absorb photons (EM waves) only when they  are in atoms, which have orbitals corresponding  to the energy of the incident light wave. And one such example is the atoms in our bones.
