ABSTRACT:
A tamper resistant and evident, self indicating instant radiation alert dosimeter (referred to as SIRAD) made by encapsulating a radiation sensing system in a polymeric material is disclosed. SIRAD is made from many layers of polymeric materials by multi-step processes. The radiation sensing system of SIRAD is encapsulated in a polymeric media made by a casting or reaction injection molding process.
