Definitions

  • the present invention relates an apparatus and method for tracking radiation sources.
  • Radiographic imaging involves the use of radiation to view structures and compositions that have varying densities and compositions.
  • Radiographic equipment typically comprises a radiation source, contained in a sealed or protected container. The radiation source is exposed for a predetermined length of time to the object to be radiated in conjunction with specific photographic film on the opposing side of the object, thereby capturing an image of the internal structure of the object.
  • Radiographic devices such as radiographic cameras are often used to capture images of the internal structure of metallic and non-metallic objects such as pipeline welds, industrial equipment, transportation equipment, civil structures or any other object that requires testing of its soundness or integrity. Radiation can be used on almost any dense materials, including concrete. Radiographic cameras and housings can be seen in EP 1325501, for example. Examples of the cameras themselves can be seen in US 5,065,033.
  • Radioactive componentry in such devices is highly carcinogenic and dangerous to all forms of life. Hence careful monitoring and containment of such materials is required by law around the world.
  • Lengthy half lives of many radiation sources some in the order of 30 years or more, means that they can remain a health and environmental concern for as long as 300 years or more.
  • Radioactive materials and products are tracked by detecting radiation levels to track the product or device. For example by installing radiation sensing equipment on mobile phones and the like and then using an array of such phones to triangulate the location of the radioactive product or device. This method requires, by its nature, a certain degree of proximity between the mobile devices and the radiation source.
