Abstract

A measurement apparatus (10) according to the present disclosure includes a generator (121) that irradiates electromagnetic waves on a measurement target (M), a receiver (122) that receives the electromagnetic waves including information on a spectroscopic spectrum of the measurement target (M), the spectroscopic spectrum changing as a result of a structural transition of a substance contained in the measurement target (M) from a first substance with an unstable structure to a second substance with a stable structure due to an external factor applied to the measurement target (M), and a controller (116) configured to acquire a measurement of the spectroscopic spectrum based on the electromagnetic waves received by the receiver (122), calculate ratio information between the first substance and the second substance based on the acquired measurement of the spectroscopic spectrum, and generate diagnostic information regarding the external factor based on the ratio information. The substance includes calcium carbonate, the first substance includes amorphous calcium carbonate or calcium carbonate hydrate, and wherein the second substance includes calcium carbonate having a calcite crystal structure.
