X-Ray Detection of Foreign Material in Large Rigid Containers
By InspX
Inspection of tall containers such as Number Ten gallon cans must reflect consideration of two important X-ray inspection principles:
- Package dimensions: to identify foreign material in a large container, you should contrast it with as little of the standard material as possible. So, inspect through a container at its narrowest dimension. For rigid packages whose height is typically greater than their diameter, inspect from the side, through the diameter
- X-rays and distance: X-ray strength decreases inversely with the square of the distance traveled. For tall containers, the X-ray strength will decrease materially from the bottom of the container to the top because the distance the beam travels increases substantially
