Quizplus · Accepted Answer

The correct formula for the intensity of a beam of nuclear radiation after passing through a material is given by $I = I_0e^{-\mu x}$, where $I_0$ is the initial intensity, $\mu$ is the attenuation coefficient, and $x$ is the thickness of the material. This formula represents the exponential attenuation of radiation as it passes through a material.
