|発明の名称||RADIATION AMOUNT MEASUREMENT DEVICE|
PROBLEM TO BE SOLVED: To provide a radiation amount measurement device capable of suppressing a measurement error, and measuring further accurately.
SOLUTION: A measurement part 12 can be attached to a skin surface 1 of a subject, in a state of forming a closed space 21 between the measurement part and the skin surface 1. An upstream channel 13 and a downstream channel 14 are provided so as to communicate with the closed space 21. Flow feeding means 15 is provided for flowing a measurement fluid from the upstream channel 13 toward the downstream channel 14 through the closed space 21. A pair of measurement sensors 17a and 17b are disposed so as to measure the same physical amount of the measurement fluid flowing in the vicinity of the measurement part 12 on the upstream channel 13 and the downstream channel 14, respectively. The respective measurement sensors 17a and 17b are formed of a humidity sensor capable of measuring humidity of the measurement fluid, a temperature sensor capable of measuring temperature of the measurement fluid, or an absorption light intensity meter capable of measuring absorption of the measurement fluid.
