| Outline of Final Research Achievements |
The data obtained in this study led to the following conclusions:
(1)It should be possible for the three stages of operation of an Ag-activated phosphate glass detector -pre-heating, reading and erasing- to be performed optically, without the need to use a thermal heating furnace, as is typically done.(2)Some advantages of using the blue RPL instead of the typically used orange RPL were demonstrated and discussed. Specifically, the use of the blue RPL with a short lifetime of 5 ns in Ag-activated glass should be suitable for real-time measurements for the radiative doses as well as for simultaneous 3D imaging.(3)The use of a confocal detection system and the high luminescent RPL glass allow one to reconstruct a 3D image by combining each image at different depths from the surface to 400 μm.(4)A fluorescent track image of X-ray irradiated phosphate glass was taken with a confocal fluorescent image microscope,though a 405 nm laser line was not suitable for the excitation source.
