Described is radiation sensitive imaging and dosimeter composition ( 20 ) containing a radiation sensitive material ( 21 ), e.g., a diacetylene (R-C-C-C-C-R', where R and R' are substituent groups) or a radiochromic dye, a polymeric binder ( 22 ) and optionally a solvent ( 23 ) and/or an activator ( 24 ). Radiation sensitive materials are incorporated into a moldable or castable material and are molded or casted into shaped-articles ( 100 ), such as coatings, films, fiber, plaques, rods and blocks. Upon exposure to high-energy radiations, radiation sentitive material develops color thereby producing a visible image. Because of the higher thickness, a significantly lower dose of radiation can be monitored and an image is produced in three dimensions. Materials, processes and usages for thick radiation sensitive devices are described. A thick block can be used for monitoring radiation dosages in the three dimensions. |
