MARSAME Release Report for TA46 Building 1
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
Environmental Protection and Compliance, Environmental Stewardship (EPC-ES) has identified materials associated with technical area 46, Building 1 (TA-46-001) that meet the criteria for unrestricted release to the public under Department of Energy (DOE) Order 458.1 Radiation Protection for the Public and the Environment (DOE 2013). We have also identified materials in certain rooms, e.g., ventilation systems and liquid drains and piping, which do not meet the criteria for unrestricted release and are to be treated as Low Level Waste (LLW). These conclusions are based on the known history of the structures combined with radiation survey data collected in 2018, and findings are consistent with DOE Order 458.1 and Los Alamos National Laboratory (LANL) Functional Series Document EPC-ES-FSD-004, Environmental Radiation Protection (LANL 2017). Sampling and data analysis, as described in this report, were sufficient to meet measurement quality objectives under the Multi-Agency Radiation Survey and Assessment of Materials and Equipment (MARSAME) manual (MARSAME 2009) and LANL procedures (LANL 2015). Final approvals for waste disposition will come from LANL’s Waste Management Program. The scope of this final release report includes structure TA-46-001. Floorplans for building 46-001 are provided in Figures 2 through 4. Metal materials included in this report are not subject to the DOE metal moratorium. While MARSAME provides guidance on statistical sampling for residual radionuclides in bulk materials, smaller miscellaneous items can be released via the release procedures outlined in LANL Policy 121 Radiation Protection (LANL 2018).
