Outline of Final Research Achievements

Microbeam Radiation Therapy (MRT) is a future radiation therapy technique using micro-planar beams of X-rays produced by synchrotrons. Despite the promising therapy effects, the micro-distribution of X-rays is so fine that there is only one measurement technique that successfully resolved the micro-patterns using Sm-doped RPL materials. On the other hand, there are limited number of materials known to show RPL. In this study, we have developed several different new materials in the form of crystal and ceramic showing RPL effects and characterized their RPL properties in detail.
