A thermoluminescent radiation dosimeter system for the remote monitoring of radiation sources. The system includes a radiation-sensitive thermoluminescent dosimeter which utilizes a new, semiconductor-doped glass material disposed at a remote location for storing energy from ionizing radiation when exposed thereto and for releasing the stored energy in the form of thermoluminescence light at a first wavelength when stimulated by exposure to light energy at a predetermined stimulating second wavelength. The system further includes an optical source for providing stimulating light energy at the predetermined stimulating second wavelength a thermoluminescent detector for measuring thermoluminescent emissions and an optical fiber for passing the predetermined stimulating light energy from the optical source to the thermoluminescent dosimeter to stimulate the thermoluminescent dosimeter to produce thermolumines- cence light from stored energy and for passing the thermoluminescence light to the thermoluminescent detector to enable the thermoluminescent detector to measure any thermoluminescent emissions occuring when the thermoluminescent dosimeter is heated by the light energy at the predetermined stimulating second wavelength.
