Relative Biological Effectiveness (RBE) is a measure used in radiation biology to compare the biological damage caused by different types of radiation. It determines the effectiveness of a specific radiation type in causing harm compared to a reference radiation. RBE values vary for different radiation sources, with high-energy particles having higher RBE than low-energy photons. Thus, RBE is used to assess the damages caused by radiation. Hence, the correct answer is option 4.
