Radiation image imaging apparatus

A radiation image imaging apparatus comprising:

• a radiation detector that detects radiation;
• a hardware processor that controls imaging of a radiation image by driving a readout circuit that reads out an image signal from the radiation detector in a first power consumption mode or a second power consumption mode in which power consumption is larger than power consumption in the first power consumption mode;
• and
• a housing that houses the radiation detector and the hardware processor, wherein
• the hardware processor
• enables imaging in the second power consumption mode in response to the radiation image imaging apparatus being in contact with a heat suppressor that suppresses an increase in a surface temperature of the housing, and
• prohibits the imaging in the second power consumption mode or stops driving of the readout circuit in the second power consumption mode after end of the imaging in the second power consumption mode in response to the radiation image imaging apparatus being not in contact with the heat suppressor.
