Naturally Occurring Radioactive Material
Know More

Such enhancements may be observed in the residues or the waste created and/or in the products or by-products and are sometimes high enough to pose a risk to workers, members of public and the environment if they are not controlled properly Materials of this kind are commonly referred to as Naturally Occurring Radioactive Material or NORM...

Site Profile
Know More

Naturally occurring radioactive materials including uranium, thorium, and radium, are present at the site and have become concentrated in some areas due to mining process To date, EPA has conducted five separate removal actions at the site An initial removal action was conducted at ,...

Uranium mining
Know More

There is less waste material removed from underground mines than open pit mines, however this type of mining exposes underground workers to the highest levels of radon gas Underground uranium mining is in principle no different from any other hard rock mining and other ores are often mined in association (eg, copper, gold, silver) Once the ....

Naturally Occurring Radioactive Materials NORM
Know More

Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon Natural radioactive elements are present in ....

Naturally occurring radioactive material (NORM)
