Overview

This analysis assesses leaching of radionuclides and external exposure in building materials made with NORM, indicating safety for outdoor use.

Key Points

  • Incorporating up to 23% unreacted ore waste in building materials does not increase radionuclide leaching.
  • Radium and uranium levels in leachate from treated blocks remained low, below regulatory safety limits.
  • Gamma radiation exposure from materials consistently measured under 0.1 mSv during the 60-day weathering study.
  • Safety assessment supports the use of NORM residues in building products for outdoor environments.
