Attenuation is greater for elements with more ____ with which the photons may interact.

Question

Quizplus · Accepted Answer

Attenuation refers to the reduction in intensity of the radiation as it passes through a material. This reduction occurs due to interactions between the photons and the atoms within the material. Electrons are the most abundant subatomic particles in an atom and therefore, elements with more electrons have a higher number of potential targets for photon interactions, resulting in higher attenuation. Therefore, Option A (electrons) is the best choice.
