Radiation detector and method of detecting radiation

摘要

A radiation detecting section (100A) including scintillation fibers (102a, 102b) is arranged in a one-dimensional, two-dimensional or three-dimensional manner. A multichannel amplitude analyzer can obtain an incident position of radiation in the radiation detecting section, and a radiation dose rate at the incident position depending upon a signal having amplitude according to a difference in arrival time between two input signals. A microcomputer (110) carries out inverse problem analysis to estimate a radiation source distribution or a spatial radiation intensity distribution. <IMAGE>
