The two main types of radiation type are ionizing and nonionizing.

The ionizing would be the radiotherapy and non-iodizing is from the sun.

Ionizing = free radical formation non ionizing (UVB) = DNA damage by formation of pyrimidine dimers

Radiation causes damage by generating hydroxyl free radicals (Pathoma chapter 3 table). Therefore, if something minimizes the damage of radiation, it has to inhibit free radical formation.

therapeutic ionizing radiation(gamma rays,x-rays); -DNA double-strand breakage -Free radical formation
