Radiation hazard assessment from NORM-added paint products in Malaysia

Introduction: Across the globe, radioactive consumer products are widely marketed for daily use. Objectives: The present study investigated commercially available ion paint, and the evaluations were using gamma (γ)-ray spectroscopy and Geant4 Monte Carlo (GMC) simulations. Methods: An assessment of...

Objectives: The present study investigated commercially available ion paint, and the evaluations were using gamma (γ)-ray spectroscopy and Geant4 Monte Carlo (GMC) simulations. Methods: An assessment of a radiological risk arising from using such products in the painting of living areas is conducted when Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) was observed, with a daily inhalation exposure dose being of particular concern.
