PENELOPE-2008 Monte Carlo simulation of gamma exposure induced by ⁶⁰Co and NORM-radionuclides in closed geometries.
We present Monte Carlo simulations of the gamma exposure in closed rooms made of steel or concrete and contaminated by ⁶⁰Co or NORM radionuclides. The computer code PENELOPE-2008 (Salvat et al., 2009) was used. Our simulations for ⁶⁰Co suggest considering detailed Monte Carlo simulations in future recommendations on clearance and exemption of materials with low radioactivity. For NORM nuclides our calculations suggest that Monte Carlo simulations are a possible alternative in case a material fails the dose rate criteria by using the RP 112 screening method.
