Table 4: Input values used in RESIdual RADioactive codes. Table 5 summarizes all input parameters considered in calculating radiological dose from the incineration of CPs containing NORMs. The HotSpot module considered in this study was the general fire module. As shown in Figure 6, the highest dose for stability class A was 0.47 mSv/y at a distance of 0.03 km from the release point for AC below 1000 Bq/kg. The dose dispersed within a distance of 10 km from the release point depends on the stability class, receptor height, long sampling time used, and the effect of meteorological conditions considered in the study. Thin lines were used for clarity. Therefore, people living within the vicinity of 10 km from the release point tend to be more exposed than those living outside the boundary of the release point. As shown in Figure 7, the highest dose for stability class A at a distance of 0.03 km from the release point for ACs above 1000 Bq/kg was 4.3 mSv/y, which was above the ICRP-recommended public dose limit of 1 mSv/y. Just as shown in Figure 6, thin lines \begin{table}

Table 5: Input values used in HOTSPOT. Figure 6: Dose from the HotSpot code for activity concentration below 1000 Bq/kg. were used for clarity. The dose shown in Figure 8 was much higher than the dose shown in Figure 6 because of the high AC above 1000 Bq/kg. People are not advised to live within 10 km of the incinerator because it makes them prone to higher exposure doses. A similar scenario used in RESRAD-ONSITE code was used in NORMALYSA to validate the dose obtained from RESRAD-ONSITE. External exposure and inhalation were the pathways considered. Radionuclide concentrations in the contaminated landfill and air of the contaminated site were used as input data for dose calculations. Table 6 summarizes all input parameters used in calculating the dose using NORMALYSA computer code. Figure 8: Dose from the NORM and LegacY Site Assessment code.
