Quizplus · Accepted Answer

Alpha particles are the largest and heaviest radiation particles that can only travel a few centimeters in air and can be blocked easily. Beta particles are smaller and more ionizing than alpha particles but can be blocked with thicker materials. Gamma rays are the smallest and most penetrating form of radiation that can travel through thick materials and even human tissues. Therefore, the correct order of penetration ability of these three types of radiation is alpha, beta, and gamma, which corresponds to choice A.
