Radiation hazard assessment from NORM-added paint products in Malaysia

چکیده
Across the globe, radioactive consumer products are widely marketed for daily use. The present study investigated commercially available ion paint, and evaluations were using gamma (?)-ray spectroscopy Geant4 Monte Carlo (GMC) simulations. An assessment of a radiological risk arising from such in painting living areas is conducted when Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) was observed, with inhalation exposure dose being particular concern. Organ doses simulated adult mathematical Medical Internal Radiation Dose 5 (MIRD5)-type phantoms, incorporating conversion factors (DCFs). Results showed that product sample code IP04 contained highest activity, i.e., 4449 ± 530, 31888 2175, 2963 405 Bq kg?1, 238U, 232Th, 40K, respectively. Contrarily, NP18 recorded lowest, 16 2 30 5, kg?1 238U paint offered most significant concentrations, mean percentages 0.026, 0.81, 0.06 212Pb, Its use designated Room 1 had resulted an annual effective 1.53 mSv y?1, assuming period 8 h day?1. In brief, these paints could result amounts exceed public limit mSv.
