This present disclosure provides a multi-ply radiation dosage indicator, which includes a first ply having two visible readable indicia thereon. The dual radiation sensitive zones are capable of changing opacity in response to exposure radiation. Each radiation sensitive zone can respond to an irradiation dose in tandem or independent of one another. Once the radiation sensitive zone exceeds the design exposure threshold, the visibility of the indicia is altered thereby providing an indication of irradiation exposure. The radiation sensitive zone may either be transparent or opaque and can change its opacity in response to exposure to radiation exceeding a predetermined threshold so as to change the visibility of the indicia.

The invention relates to a polymeric dosimetric sheet with a thickness of 0.8 to 10.0 mm which contains a radiochromic dye and other additives and which reacts with x-ray or other ionizing radiation to form a stable color. The invention also relates to a stack of the dosimetric sheets which constitute a three-dimensional dosimeter. Upon irradiation, the sheet stack captures the radiation field of an applied radiation treatment plan. The irradiated sheet stack is disassembled and scanned with readily available devices to afford an array of two-dimensional images which can verify the treatment plan throughout the entire target volume by computerized methods.
