TENORM
Naturally-Occurring Radiation: 

Gold and Silver Mining Wastes

TENORM

While few studies have been done on these ores, some western mines produced uranium as a secondary product when extracting precious metals. Pitchblende (a naturally occurring material containing low concentrations of uranium) has been found in the same ores as gold and silver. Waste rock from some of these mines may be radioactive.

The Radiation in TENORM Summary Table provides a range of reported concentrations, and average concentration measurements of NORM associated with various waste types and materials.
