6-1 Mean Activity Concentrations of Gross Alpha Activity and Total Radium (²²⁶Ra plus ²²⁸Ra) for the Igneous-Intrusion Scenario, HTOM. The Concentrations are Calculated for a Representative Volume of Groundwater of 3,000 acre-feet at the Accessible Environment, Which is the Same as the RMEI Location
6-2 Mean Activity Concentrations of Gross Alpha Activity and Total Radium (²²⁶Ra plus ²²⁸Ra) for the Igneous-Intrusion Scenario, LTOM. The Concentrations are Calculated for a Representative Volume of Groundwater of 3,000 acre-feet at the Accessible Environment, Which is the Same as the RMEI Location
6-3 Mean Dose to Critical Organs for ⁹⁹Tc, ¹⁴C, and ¹²⁹I for the Igneous-Intrusion Scenario, HTOM. The Concentrations are Calculated for a Representative Volume of Groundwater of 3,000 acre-feet at the Accessible Environment, Which is the Same as the RMEI Location
6-4 Mean Dose to Critical Organs for ⁹⁹Tc, ¹⁴C, and ¹²⁹I for the Igneous-Intrusion Scenario, LTOM. The Concentrations are Calculated for a Representative Volume of Groundwater of 3,000 acre-feet at the Accessible Environment, Which is the Same as the RMEI Location
