1. An ionizing radiation tolerant camera, comprising:a camera module comprising, an electronic image sensor and a lens package, said electronic image sensor and lens package are in fixed alignment to each other,an ionizing radiation shielding enclosure within which said camera module is disposed, said ionizing radiation shielding enclosure defining an opening for allowing passage of light into said ionizing radiation shielding enclosure and to the image sensor,an ionizing radiation shield,a heat absorbing cooling element connected to the camera module, said cooling element functioning to dissipate heat from the camera module,a pivot structure for simultaneously pivoting the ionizing radiation shielding enclosure together with the camera module, with the electronic image sensor and lens package within the ionizing radiation shielding enclosure, as a unit, relative to the ionizing radiation shield between an adjustable active position in which the ionizing radiation shielding enclosure opening is uncovered, and a shielded position in which the ionizing radiation shielding enclosure opening is directed towards the ionizing radiation shield; anda support structure on which the ionizing radiation shield is mounted and on which the pivot structure is mounted to enable the ionizing radiation shield and the ionizing radiation shielding enclosure, with the camera module therein, to move together in a desired rotational pan direction. 2. An ionizing radiation tolerant camera as claimed in claim 1, wherein the heat absorbing cooling element is thermally connected to a cooling device. 3. An ionizing radiation tolerant camera as claimed in claim 2, wherein the cooling device comprises a thermoelectric cooling module. 4. An ionizing radiation tolerant camera as claimed in claim 1, wherein heat pipes are provided for dissipation of heat from the heat absorbing cooling element to a position outside of the ionizing radiation shielding enclosure. 5. An ionizing radiation tolerant camera as claimed in claim 4, wherein the heat pipes extend substantially horizontally. 6. An ionizing radiation tolerant camera as claimed in claim 4, wherein the heat pipes are connected to a heat sink mounted on an outside wall of the enclosure. 7. An ionizing radiation tolerant camera as claimed in claim 1, wherein the ionizing radiation shielding enclosure is made from a material comprising hydrocarbon plastics. 8. An ionizing radiation tolerant camera as claimed in claim 7, wherein the ionizing radiation shielding enclosure is made from a material comprising boron. 9. An ionizing radiation tolerant camera as claimed in claim 1, wherein the ionizing radiation shielding enclosure has an average thickness of 3-10 cm. 10. An ionizing radiation tolerant camera as claimed in claim 9, wherein the ionizing radiation shielding enclosure has an average thickness of about 5 cm. 11. An ionizing radiation tolerant camera as claimed in claim 1, wherein the opening is covered by a transparent front panel. 12. An ionizing radiation tolerant camera as claimed in claim 1, wherein the camera module is arranged in an insulating and moisture-proof body. 13. An ionizing radiation tolerant camera as claimed in claim 12, wherein the camera module is enclosed in a housing. 14. An ionizing radiation tolerant camera as claimed in claim 13, wherein the housing comprises neutron radiation shielding material. 15. An ionizing radiation tolerant camera as claimed in claim 12, wherein the camera module is enclosed in a gamma radiation shielding layer. 16. An ionizing radiation tolerant camera as claimed in claim 1,further comprises a motorized actuator for said pivot structure; andthe ionizing radiation shielding enclosure with the camera module disposed therein, is powered by said motorized actuator to pivot as a unit in relation to said ionizing radiation shield between a shielded position in which the opening of the ionizing radiation shielding enclosure is directed toward said ionizing radiation shield and the adjustable operating position in which the opening of the ionizing radiation shielding enclosure is uncovered.
