The linear absorption coefficient µ is a function of the type of material used for the shield and of the energy of the incident photons. It has the dimensions of (length)−1 and is usually expressed in m−1 or mm−1. 4 Dosimetry for Industrial Radiation Processing The ability of ionizing radiation to induce effects that are potentially of use industrially has been known for many decades. However, it was not until the development of large-scale radiation sources, both radioisotopes and machines, in the 1950s that industrial scale radiation processing became a practical reality.

In 1973, Sellafield had a problem with the corrosion of the metal cans containing the spent fuel rods, which led to a sharp increase in radioactivity levels [28]. 2 Cap de la Hague The Cap de la Hague center, located on the Normandy coast of France, commenced reprocessing spent fuel from commercial graphite/gas reactors in 1966. The complex was completed 10 years later by a high-activity oxide head-end facility to provide for reprocessing light water reactor (LWR) fuel. Considering routine discharges of low-level radioactive wastes from Cap de la Hague, one of the principal releases concerns liquid effluents discharged to the aquatic environment [30].

The body can, however, tolerate high doses to local tissue volumes. With internal nuclear medicine, a radioactive source is administered to the patient. It could be in form of a drug or carrier material labeled with a radioactive material. The carrier is chosen so that it is preferably taken up by the malignant organ or tissue. The most frequently used radionuclide in nuclear medicine is technetium 99 Tc. Strict quality control procedures are essential for safe practice and disposal of these hazardous materials.
