Read about the optical properties and mutagenic effects of ultraviolet radiation. I want to increase the mutation rate of my shrimp and triops and thought of irradiating them with a UV source, and I was checking that UV would produce the right kinds of mutations and wouldn't simply kill or sterilise them, which kind of UV to use (UVA, UVB or UVC), a ballpark figure for what dose to start with and what materials to use for constructing an irradiation chamber.
