Which radiation type has a greater potential to cause skin damage due to its energy levels?

The choice indicating UVB radiation is the one with a greater potential to cause skin damage due to its energy levels. UVB rays, which are part of the ultraviolet spectrum, have a higher energy level compared to UVA rays. This higher energy allows UVB rays to penetrate the outer layers of the skin more effectively, leading to direct DNA damage in skin cells. This damage can result in sunburn and plays a significant role in the development of skin cancer. UVB rays are also the primary cause of erythema, or redness of the skin, which is a key indicator of damage.

While UVA radiation can also contribute to skin damage, particularly by promoting skin aging and indirectly affecting DNA through the production of free radicals, its energy levels are lower than those of UVB rays. UVC radiation has the highest energy levels among the three types, but it does not reach the Earth's surface because it is absorbed by the ozone layer, making its potential for causing skin damage negligible in practical terms for human exposure. Thus, when considering the skin damage potential related to energy levels of radiation, UVB stands out as having the most significant impact.
