Which of the following provides the minimum amount of protection you need to block the gamma radiation?

a. lead suit
b. suntan lotion
c. thick leather
d. t-shirt
e. none of these

Answer : The correct option is, (A) lead suit

Explanation :

Penetration power : It is the movement of rays or the particles through an object.

As we know that the more the energy of a particle, the 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 alpha, beta and gamma rays varies greatly.

The alpha particles are restricted by the paper.

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

The blocking of gamma rays is very difficult. It can be blocked only by concrete, lead, or other heavy shielding.

Hence, the material provides the minimum amount of protection you need to block the gamma radiation is, lead suit.

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.
