Radiation dosimetry in the ultraviolet is described using the intrinsic ultraviolet response of a novel thermoluminescent semiconductor‐doped Vycor glass. A linear response to 185 nm light was measured over the range 0.1 to 1000 &mgr;J/cm2. The long wavelength limit of the sensitivity of the glass is ∼290 nm, indicating the utility of the glass as an effective solar blind dosimeter. ©1995 American Institute of Physics.
