Abstract :
The authors present an update on research started three years ago with the goal of developing plastic scintillators able to endure annual doses of 104 to 105 Gy or more. Attention is given to radiation damage to plastic scintillators, techniques to improve radiation resistance (wavelength shifting and radiation-tolerant plastic bases), and other issues. It is concluded that, although the studies of scintillators must continue in order to define the limits of current capabilities, there is a need to move beyond the study of `naked´ scintillators (whether as plates or optical fibres) and to study them `dressed´ within a detector system
