Industrial Uses For Radioactive Isotopes
Cobalt-60 (Co-60 or 60Co) is useful as a gamma ray source because it can be produced—in predictable quantity, and high activity—by simply exposing natural cobalt to neutrons in a reactor for a given time. It is used for
- sterilization of medical supplies, and medical waste;
- radiation treatment of foods for sterilization (cold pasteurization);
- industrial radiography (e.g., weld integrity radiographs);
- density measurements (e.g., concrete density measurements); and
- tank fill height switches.

Famous quotes containing the word industrial:
“The two most far-reaching critical theories at the beginning of the latest phase of industrial society were those of Marx and Freud. Marx showed the moving powers and the conflicts in the social-historical process. Freud aimed at the critical uncovering of the inner conflicts. Both worked for the liberation of man, even though Marx’s concept was more comprehensive and less time-bound than Freud’s.”
—Erich Fromm (1900–1980)
