Radiation imaging cassette

A radiation imaging cassette capable of communicating wirelessly with an external console that issues imaging commands, comprising:

• a housing that contains:
• a solid state detector that records image information when irradiated with radiation that bears the image information, a first communicating means for communicating wirelessly with the external console, a second communicating means for communicating with the external console in a manner other than wirelessly, and a control means for controlling the operations of the first communicating means and the second communicating means;
• and
• a metal detecting means for detecting metal in the periphery of the housing;
• the control means ceasing the operation of the first communicating means and causing the radiation imaging cassette to communicate with the external console using the second communication means, in response to detection of metal by the metal detecting means.
