  • Backscatter detection inspection apparatus for tubular goods
    Patent number: 4580053
    Abstract: Disclosed is a device employing radiation emission and backscatter detection for inspection of tubular goods for defects. A shutter mechanism is interposed between the radiation source and the tubular goods during inspection operations to control the transmission of radiation. The shutter mechanism is electrically activated to an open position and resiliently biased to a closed position. When the shutter mechanism is deactivated, it is automatically closed to prevent undesired emission of harmful radiation.
