The correct option is C.

A 2-cm-thick piece of cardboard over a radiation source would be most effective for protecting against alpha radiation.

What does alpha mean in radiation?

Alpha particles (α) are positively charged and made up of two protons and two neutrons from the atom's nucleus. Alpha particles come from the decay of the heaviest radioactive elements, such as uranium, radium, and polonium.

Is alpha radiation harmful?

Alpha radiation is not as dangerous because it is unlikely to reach living cells inside the body. beta and gamma radiation are the most dangerous sources because they can penetrate the skin and damage the cells inside.
