CAMERA AND COOLING METHOD OF IMAGING SENSOR

PROBLEM TO BE SOLVED: To cool a sensor module at a high speed.SOLUTION: A camera includes: a sensor module 1 that acquires data for visualizing distribution state of a radioactive material by receiving radiation; fins 11-1 and 11-2; a heat conduction member 3 that thermally contacts with the sensor module 1; coolers 8-1 and 8-2 that transfer the heat from the sensor module 1 to the fins 11-1 and 11-2 via the heat conduction member 3; and covers 16-1 and 16-2. In the camera 10, while the coolers 8-1 and 8-2 are not in operation, the fins 11-1 and 11-2 are covered to reduce the heat transmitted to the sensor module 1 from the outer air via the fins 11-1 and 11-2 to prevent the sensor module 1 from getting a high temperature. Thus, in the camera 10, the sensor module 1 can be cooled to a predetermined temperature at a high speed.
