Apparatus for recording an image of the local distribution and the radiation intensity of radioactive materials deposited in a space

Claim 1

AN APPARATUS FOR DETERMINING THE LOCAL DISTRIBUTION AND RADIATION INTENSITY OF RADIOACTIVE MATERIALS DEPOSITED IN A SPACE, COMPRISING A CHAMBER SHIELDED ON ALL SIDES AGAINST RADIOACTIVE RADIATION, REPLACEABLE CARRIER MEANS INCLUDING AN ILLUSTRATION OF THE SPACE TAKEN FROM A SPECIFIC VIEWING ANGLE, SAID ILLUSTRATION BEING COATED WITH A RADITION-SENSITIVE FILM AND BEING MOUNTED IN A SPECIFIC PLANE IN SAID CHAMBER, AND A SPHERE PARTLY DEFINING SAID CHAMBER AND SPACED FROM SAID RADIATION-SENSITIVE FILM, SAID SPHERE BEING FORMED WITH A CENTRAL BORE COMMUNICATING BETWEEN SAID CHAMBER AND THE EXTERIOR THEREOF AND BEING ROTATABLE ABOUT A PAIR OF MUTUALLY PERPENDICULAR AXES, ONE OF SAID AXES BEING LOCATED TRANSVERSE TO SAID SPECIFIC PLANE AND THE OTHER OF SAID AXES BEING LOCATED SUBSTANTIALLY PARALLEL THERETO, SAID ONE AXIS COINCIDING AT A POSITION OF SAID SPHERE WITH THE AXIS OF SAID BORE, SAID SPHERE BEING PROVIDED WITH A PAIR OF OPPOSED TRUNNIONS ALIGNED ON THE OTHER OF SAID AXES, AND MECHANISM FOR ROTATING SAID SPHERE, SAID MECHANISM COMPRISING FIRST ROTATABLE MEANS SURROUNDING SAID SPHERE AND HAVING AN AXIS OF ROTATION COINCIDING WITH SAID ONE AXIS, DRIVE MEANS FOR ROTATING SAID FIRST ROTATABLE MEANS ABOUT SAID AXIS OF ROTATION, SAID TRUNNIONS BEING DIAMETRICALLY MOUNTED IN SAID FIRST ROTATABLE MEANS, AND SECONE ROTATABLE MEANS CONNECTED BETWEEN SAID FIRST ROTATABLE MEANS AND SAID SPHERE FOR ROTATING SAID SPHERE ABOUT SAID OTHER AXIS AS SAID FIRST ROTATABLE MEANS IS ROTATED ABOUT SAID AXIS OF ROTATION BY SAID DRIVE MEANS, SO THAT AN AREA OF THE SPACE WHEREIN RADIOACTIVE MATERIALS ARE DEPOSITED AT THE EXTERIOR OF SAID CHAMBER AND A CORRESPONDING AREA OF SAID RADIATION-SENSITIVE FILM ARE SIMULTANEOUSLY SCANNABLE AT SAID SPECIFIC VIEWING ANGLE THROUGH SAID BORE, WHEREBY SAID SPHERE ACTS AS A CAMERA OBJECTIVE FOCUSSING RADIATION IN THE EXTERIOR AREA THROUGH SAID BORE ONTO SAID RADIATION-SENSITIVE FILM FOR FORMING A RECORDED IMAGE OF THE RADIATION SUPERIMPOSED ON SAID ILLUSTRATION.

Claim 2

AN APPARATUS FOR DETERMINING THE LOCAL DISTRIBUTION AND RADIATION INTENSITY OF RADIOACTIVE MATERIALS DEPOSITED IN A SPACE, COMPRISING A CHAMBER SHIELDED ON ALL SIDES AGAINST RADIOACTIVE RADIATION, REPLACEABLE CARRIER MEANS INCLUDING AN ILLUSTRATION OF THE SPACE TAKEN FROM A SPECIFIC VIEWING ANGLE, SAID ILLUSTRATION BEING COATED WITH A RADITION-SENSITIVE FILM AND BEING MOUNTED IN A SPECIFIC PLANE IN SAID CHAMBER, AND A SPHERE PARTLY DEFINING SAID CHAMBER AND SPACED FROM SAID RADIATION-SENSITIVE FILM, SAID SPHERE BEING FORMED WITH A CENTRAL BORE COMMUNICATING BETWEEN SAID CHAMBER AND THE EXTERIOR THEREOF AND BEING ROTATABLE ABOUT A PAIR OF MUTUALLY PERPENDICULAR AXES, ONE OF SAID AXES BEING LOCATED TRANSVERSE TO SAID SPECIFIC PLANE AND THE OTHER OF SAID AXES BEING LOCATED SUBSTANTIALLY PARALLEL THERETO, SAID ONE AXIS COINCIDING AT A POSITION OF SAID SPHERE WITH THE AXIS OF SAID BORE, SAID SPHERE BEING PROVIDED WITH A PAIR OF OPPOSED TRUNNIONS ALIGNED ON THE OTHER OF SAID AXES, AND MECHANISM FOR ROTATING SAID SPHERE, SAID MECHANISM COMPRISING FIRST ROTATABLE MEANS SURROUNDING SAID SPHERE AND HAVING AN AXIS OF ROTATION COINCIDING WITH SAID ONE AXIS, DRIVE MEANS FOR ROTATING SAID FIRST ROTATABLE MEANS ABOUT SAID AXIS OF ROTATION, SAID TRUNNIONS BEING DIAMETRICALLY MOUNTED IN SAID FIRST ROTATABLE MEANS, AND SECONE ROTATABLE MEANS CONNECTED BETWEEN SAID FIRST ROTATABLE MEANS AND SAID SPHERE FOR ROTATING SAID SPHERE ABOUT SAID OTHER AXIS AS SAID FIRST ROTATABLE MEANS IS ROTATED ABOUT SAID AXIS OF ROTATION BY SAID DRIVE MEANS, SO THAT AN AREA OF THE SPACE WHEREIN RADIOACTIVE MATERIALS ARE DEPOSITED AT THE EXTERIOR OF SAID CHAMBER AND A CORRESPONDING AREA OF SAID RADIATION-SENSITIVE FILM ARE SIMULTANEOUSLY SCANNABLE AT SAID SPECIFIC VIEWING ANGLE THROUGH SAID BORE, WHEREBY SAID SPHERE ACTS AS A CAMERA OBJECTIVE FOCUSSING RADIATION IN THE EXTERIOR AREA THROUGH SAID BORE ONTO SAID RADIATION-SENSITIVE FILM FOR FORMING A RECORDED IMAGE OF THE RADIATION SUPERIMPOSED ON SAID ILLUSTRATION.
