Atarget is shielded from a radioactive sample by a sheet of metal. what kind of radiation can pass through the sheet of metal and hit the target? gamma rays only gamma rays and beta particles beta particles only beta particles and alpha particles

A. o. I know gamma can I Hope this helps

A now i remember yeah gamma only

Answer : The correct option is, gamma rays only

Explanation :

Penetration power : It is defined as the movement of particles or rays through an object. As more the energy of a particle, more will be the penetrating power.

The increasing order of the penetration power of alpha rays, beta rays, and gamma rays will be,

Alpha rays < Beta rays <  Gamma rays

The penetrating power of the given rays varies greatly.

The alpha particles can be restricted by a few pieces of paper.

The beta particles can be pass through the paper but can not pass by the aluminum foil.

The blocking of gamma rays are the most difficult. It can be blocked by concrete, lead, or other heavy shielding.

Hence, the radiation can pass through the sheet of metal and hit the target is, gamma rays only

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
