X-Ray Basics
The Basic Principles
X-rays are simply a high energy light source. Its wave length is higher than visual light but follows the same basic principles.
There are two types of X-ray Systems: Automatic and Manual. Automatic system utilize linear array technology and Manual systems use image intensifying technology. The base resolution of an automatic system is determined by the diode size and the speed of the product. A Manual Systems resolution is infinite and only limited by video techniques. In both cases, the physics associated with X-Rays are the same.
Sensitivity is determined by the systems based resolution and product density. The more dense the product the more difficult it becomes to detect a foreign material. When dealing with dense foreign, objects the atomic number associated with such contaminants must be greater than that of the product. For example: a cherry pit is hard but less dense than the meat of the cherry, therefore it is not detectable by X-Rays.
A rule of thumb is that if a contaminant floats in water then it will not be detected by X-Rays.
Detectable: Metal, Glass, Stones, Bones, Rubber, Void/Missing Products and Seashells
Non-Detectable: Paper, Pits, Nutshells, Foil, Aluminum Metals and Wood.
