A radiation monitor (1) is for measuring a dose rate, and has : a fluorescent body represented by general formula (1); a radiation detection unit (2) provided with the fluorescent body; an optical fiber (3) that transmits photons generated from the radiation detection unit (2); a photodetector (4) that converts each of the transmitted photons into an electric pulse signal; a counter (5) that counts electric pulse signals; and an analyzer/display unit (6) that determines the dose rate of radiation on the basis of the count of electric pulse signals from the relationship between dose rate of radiation and count rate of a single photon. General formula (1) ATaO4 : B, wherein A and B are selected from at least one element in the group consisting of rare-earth elements of 4f-4f electronic transition.
