Gamma radiography system and method of using a gamma radiography system

A method for using a gamma radiography device, comprising:

• placing a gamma source material in a gamma source holder, wherein the gamma source holder is attached to a first end of a shaft handle;
• placing the gamma source holder in a source container;
• inserting a second end of the shaft handle through a central aperture of a source container cover;
• screwing threads on the source container to threads of a roof of a shielded housing;
• installing a handle grip on the second end of the shaft handle;
• transporting the gamma radiography device to a radiation station;
• inserting at least one beam modifying device into an extension of the shielded housing;
• placing the gamma source holder into a deployed position by lowering the shaft handle towards the shielded housing until the source holder contacts a floor of the shielded housing;
• keeping the gamma source holder in the deployed position for a desired imaging interval;
• and
• placing the gamma source holder into a non-deployed position by raising the shaft handle away from the shielded housing until the gamma source holder contacts the source container cover.

A method for assembling a gamma radiation device, comprising:

• welding an extension to a first wall of a shielded housing, wherein the first wall has a beam aperture configured to pass a gamma radiation beam through the extension;
• attaching a first leg to a first corner of an underside of the shielded housing;
• attaching a second leg to a second corner of the underside of the shielded housing, wherein the first corner and the second corner are opposite the extension;
• attaching a third leg to a center of an underside of the extension;
• installing a caster wheel on an end of each leg;
• connecting a wheel motor to the caster wheel directly beneath the extension;
• placing a gamma source holder attached to a shaft handle in a source container such that a grip end of the shaft handle extends through a central aperture of a source container cover;
• screwing threads on the source container to threads of a roof of the shielded housing;
• installing a handle grip on the grip end of the shaft handle;
• installing a linear motor to the source container and the shaft handle;
• installing an antenna on an exterior of the shielded housing;
• installing a controller on the exterior of the shielded housing;
• and
• connecting the controller to the antenna, the wheel motor, and the linear motor, wherein the controller is configured to receive, from a remote control device, direction commands and actuate the wheel motor to transport the gamma radiation device to a radiation station based on the direction commands, wherein the controller is further configured to receive, from the remote control device, shaft handle direction commands and actuate the linear motor to one of lower and raise the shaft handle based on the shaft handle direction commands.
