The present invention includes : a radiation detecting unit 2 including a fluorescent body 7 expressed by the formula ATaO4 : B, C (in the formula, A is selected from at least one kind of element from among rare-earth elements involving 4f-4f transitions, B is selected from at least one kind of element, different from A, from among rare-earth elements involving 4f-4f transitions, and C is selected from at least one kind of element from among rare-earth elements involving 5d-4f transitions); an optical fiber 3 that transmits photons generated by the fluorescent body 7; a light detector 4 that converts the photons transmitted via the optical fiber 3 one by one into electrical pulse signals; a counter 5 that counts the number of electrical pulse signals converted by the light detector 4; an analysis and display device 6 that obtains a radiation dose rate on the basis of the number of electrical pulse signals counted by the counter 5 according to the relationships between the counting rate of single photons and the radiation dose rate.
