1. An implantable radiation sensing device, comprising:
- an x-ray radiation sensor device operable to detect, in vivo, one or more x-ray radiation stimuli associated with an x-ray radiation exposure event, the x-ray radiation sensor device including at least a first direction-selective sensor for detecting, in vivo, one or more x-ray radiation stimuli propagating in a first direction, and a second direction-selective sensor for detecting, in vivo, one or more x-ray radiation stimuli propagating in a second direction, the second direction different from the first direction; and
an x-ray radiation direction-determination device operable to determine at least one of an x-ray radiation source location or an x-ray radiation propagation direction based on one or more measurand outputs from at least one of the first direction-selective sensor or the second direction-selective sensor.
