UV-B treatments for skin conditions such as psoriasis, vitiligo, and atopic dermatitis are administered in very low doses, often lasting only a few minutes or less than a minute when using lamps emitting 290-300 nanometer light. This low dosage does not significantly increase the risk of skin cancer, making UV-B phototherapy a safe treatment ...
Richard L. Riley, initially a student of Wells, continued the study of airborne infection and UVGI throughout the 1950s and 60s, conducting significant experiments in a Veterans Hospital TB ward. Riley successfully demonstrated that UVGI could efficiently inactivate airborne pathogens and prevent the spread of tuberculosis.

[66] All bands of UV radiation damage collagen fibers and accelerate aging of the skin. Both UVA and UVB destroy vitamin A in skin, which may cause ...
