1. An imaging capsule with a fail-safe radiation mechanism, comprising:

  • a radiation source;

    a first rotatable disk with the radiation source mounted thereon, the first rotatable disk having a collimator structure allowing the emission of radiation from the radiation source substantially only from a few locations on the circumference of the first disk;

    a second rotatable disk surrounding the circumference of the first rotatable disk and configured to rotate relative to the first rotatable disk, the second rotatable disk including areas that block radiation and areas that are transparent to the emission of radiation, wherein in a rest position the second rotatable disk is situated relative to the first rotatable disk such that the areas that block radiation are blocking the emission of radiation from the few locations on the circumference of the disk that allow the emission of radiation;

    a connector assembly configured to couple the first rotatable disk to the second rotatable disk; and

    a motor for rotating the one of the rotatable disks relative to the other of the rotatable disks,wherein the first rotatable disk and second rotatable disk are initially in the rest position blocking the emission of radiation until the motor is activated to rotate the one rotatable disk and allow the emission of radiation, andwherein the connector is configured to automatically return the first rotatable disk and the second rotatable disk to the rest position when the motor is deactivated.
