ABSTRACT:
Radiation detecting solid elements consisting of conductive polymers and radiation sensitive materials which are capable of generating radiation induced substances composing the dopant of the conductive polymers. The elements are monolayer sheets obtained by impregnating or compounding the conductive polymers, such as, polythiophene and polyselenophene, with radiation sensitive materials, such as, diphenyliodonium chloride and triphenylsulfonium hexafluoroarsenate(V). The elements are also laminated sheets consisting of conductive polymer films and radiation sensitive material containing films. As radiation exposure causes variation in electrical conductivity and absorption spectrum of the elements, radiation can be detected by the variation of these properties.
