How can I get ultraviolet B rays to treat a skin problem?

ANSWER

You can get UVB rays from sunlight, especially summer noontime sun. But sunlight also carries UVA rays, the kind linked to cancer and rapid aging. Your doctor can treat you with UVB rays from a phototherapy unit in his office. You can get one to use at home, too, but these lamps can also give off UVA rays.
