Radiation exposure dose-history indicator |
摘要 |
The present composition for use in radiation exposure dose-history indicators comprises a radioactive ray-absorber and/or a radioactive ray-excited fluorescence-emitting agent, a color-developing and electron-donating organic compound and an active species-generating organic compound, which can initiate the color development of the electron-donating organic compound through the application of radioactive rays. The indicator sheet for indicating the radiation exposure dose-history comprises a matrix sheet; and a color-developing layer, which contains a color-developing and electron-donating organic compound, an active species-generating organic compound, which can initiate the color development of the electron-donating organic compound through the application of radioactive rays, and a radioactive ray-absorber and/or a radioactive ray-excited fluorescence-emitting agent and which is applied to at least part of the surface of the matrix sheet. <IMAGE> |
