Cole is working with radioactive particles and has set up a shield made of aluminum for protection. Which of the following will he be protected from?
A.) Only alpha particles and beta particles
B.) Only alpha particles
C.) Alpha, beta, and gamma particles
D.) Only gamma rays

C.) Alpha, beta, and gamma particles

Explanation:

A dense shield of aluminium can protect Cole from all the listed types of radiation produced from the radioactive particles.

A radioactive protector has very unique and specie ability to contain and prevent the movement of radiations of any types from going into the body.

The strongest and most penetrating radiations are the gamma rays. Any material that can prevent the movement of these rays can halt alpha and beta particles too.

An aluminium shield is made up of multiple layers of aluminium stacked together and it provides enough resistance.
