Abstract
A process for treating naturally occurring radioactive material (NORM) comprises use of NORM as a mud constituent in a drilling mud manufacturing process and particle size reduction of the NORM particles during or before that process to attain a selected particle size corresponding to that of a particulate drilling mud component, said particle size reduction being optionally accompanied by additional mixing, if necessary, of the NORM and mud component particles, the aim of said use being the achievement of irreversible dilution of the NORM particles in said component to nullify the radioactive nature thereof.
