Quizplus · Accepted Answer

Gamma radiation has the smallest wavelength and highest frequency among all types of radiation, making it the most highly penetrating. It can travel through thick layers of materials such as concrete and lead. Alpha and beta radiation have larger wavelengths and lower frequencies, making them less penetrating. Ultraviolet radiation has even larger wavelengths and lower frequencies than alpha and beta radiation, and as such is also less penetrating.
