The connector assembly of  claim 4 , wherein the shield protector is a rotor rotatably attached to an interior surface of the front plate between the front plate and the first endplate, the rotor including a first rotor hole formed in the rotor locating a port shield to be aligned with the first opening, and a second rotor hole adapted to be aligned with the first opening upon rotation of the rotor. claim 4 6. The connector assembly of  claim 5  further comprising a slider adjacent the rotor that prevents rotation of the rotor, wherein the front plate hole is adapted to receive the guide cable fitting to move the slider to allow the rotor to rotate and expose the first opening through the second rotor hole. claim 5 7. The connector assembly of  claim 6  further comprising a knob rotatably attached to an exterior surface of the front plate and positioned to cover and uncover the front plate hole, wherein the knob is rotatable to expose the front plate hole such that the guide cable fitting is insertable within the front plate hole to move the slider, and the knob is thereby further rotatable to cause the rotor to rotate to align the second rotor hole with the first opening and the front plate hole to expose the source. claim 6 8. The connector assembly of  claim 5  wherein the port shield is tungsten. claim 5 9. A radiographic camera apparatus, the apparatus comprising: wherein the rotor is locked in position with the radiation shield aligned with the second opening and is adapted to be unlockable when a fitting is engaged in the hole of the front plate and wherein the front plate does not include a removable plug for insertion in the hole when in a storage condition. a housing having an interior chamber, a first opening and a second opening formed by the housing, the first opening opposite the second opening on the housing;  a lock assembly in communication with the housing at the first opening;  a front plate having an interior and an exterior surface and defining a hole, the front plate in communication with the housing at the second opening to align the hole with the second opening;  a conduit within the housing containing a radiation source and in communication with the lock assembly at one end and the front plate at the other end, a pathway being formed by the conduit to an exterior of the housing through the front plate; and  a rotor rotatably attached to the interior surface of the front plate, the rotor defining a first rotor hole aligned with the second opening and having a radiation shield therein, and the rotor defining a second rotor hole for alignment with the second opening upon rotation of the rotor, 10. The apparatus of  claim 9  further comprising a knob rotatably attached to the exterior surface of the front plate and positioned to rotatably cover and uncover the hole of the front plate, wherein the knob is rotatable to expose the hole in the front plate and the shield in the first rotor hole, and the knob is further rotatable to cause the rotor to rotate to align the second rotor hole with the second opening when the rotor is unlocked. claim 9 11. The connector assembly of  claim 9  further comprising a slider adjacent the rotor that prevents rotation of the rotor, wherein when the slider is caused to move the rotor is allowed to rotate and expose the second opening through the second rotor hole. claim 9 12. The connector assembly of  claim 11  wherein upon insertion of the fitting into the hole of the front plate, the fitting is rotated and causes the slider to move, thereby allowing the rotor to rotate and expose the second opening through the second rotor hole. claim 11 13. The connector assembly of  claim 12  further comprising at least one ear on the fitting, wherein the ear fits within the hole and upon rotation of the fitting interacts with and moves the slider to allow rotation of the rotor to occur. claim 12 14. A connector assembly for a radiographic camera, comprising: wherein the radiation source cannot move through the radiation source opening until the radiation shield protector is moved to the unblocking position and wherein position of the radiation shield protector is independent of operation of a lock assembly. a connection element adapted to engage with a guide cable, the connection element including an opening aligned with a radiation source opening in the camera through which a radiation source can pass;  a radiation shield protector provided with the connection element, the radiation shield protector movable between blocking and unblocking positions, where in the blocking position the radiation shield protector blocks the radiation source opening and in the unblocking position the radiation shield protector does not block the radiation source opening; and  a lock that is adapted to lock the radiation shield protector in the blocking position and is adapted to unlock the radiation shield protector upon activation of a key located outside the camera at the connection element end of the camera to allow the radiation shield protector to move to the unblocking position, 15. The connector assembly of  claim 14 , wherein: claim 14 the shield protector comprises a rotor that may rotate to block and unblock the radiation source opening, and the lock comprises a slider that is adapted to engage with the key to unlock the rotor from the blocking position. 16. The connector assembly of  claim 15 , further comprising: a knob adapted to move the rotor to unblock the radiation source opening upon engagement of the slider with the key. claim 15 17. The connector assembly of  claim 14 , wherein the lock is adapted to engage with a guide cable fitting that acts as the key. claim 14 18. The connector assembly of  claim 17 , wherein the lock comprises a slider that unlocks the shield protector from the blocking position when the guide cable fitting is secured to the opening in the connection element. claim 17 19. A method of operating a radiation camera, comprising: wherein the steps of releasing and moving the radiation shield protector are independent of operation of a lock assembly on the camera. releasing a radiation shield protector that blocks a radiation source opening at a connector assembly in the camera by attaching a guide cable fitting to the connector assembly;  moving the radiation shield protector to unblock the radiation source opening by activating a mechanism outside a housing of the camera at the connector assembly end; and  moving a radiation source from within the camera through the radiation source opening, 20. The method of  claim 19 , wherein the mechanism is incorporated into the guide cable fitting. claim 19 21. The method of  claim 19 , wherein the step of releasing the shield protector comprises engaging the guide cable fitting with a slider. claim 19 22. The method of  claim 19 , wherein the step of moving the shield protector comprises rotating a knob attached to the shield protector to align a hole in the shield protector with the radiation source opening wherein the radiation source is thereafter movable through the radiation source opening. claim 19
