Measurement device and measurement probe

This measurement device (1) is provided with a sensing part (3) including at least a fluorescent substance for which the emission of fluorescence is stopped through the effect of radiation and a measurement unit (5) for measuring the dose of radiation irradiated onto the sensing part (3) on the basis of the amount by which the intensity of the fluorescence emitted from the fluorescent substance included in the sensing part (3) decreases through the effect of the radiation on at least a portion of the fluorescent substance. The fluorescent substance includes at least one from among lithium, boron, and gadolinium. The measurement unit (5) measures the dose on the basis of a value arrived at by subtracting the intensity of the fluorescence after the radiation has been irradiated onto the sensing part (3) from the intensity of the fluorescence before the radiation was irradiated onto the sensing part (3). 本发明的测量装置(1)包括：至少包含会因放射线作用而停止发出荧光的荧光物质的感应部(3)；以及测量部(5)，该测量部(5)基于由包含在感应部3中的荧光物质发出的荧光强度由于放射线作用于荧光物质的至少一部分而衰减时的衰减
