Title: Radioactivity measurements for Los Alamos National Laboratory`s permitted septic systems

Abstract

The purpose of this study is to identify septic tanks containing concentrations of radioactive materials that exceed specified screening levels so that septage exceeding these screening levels is not disposed of at LANL`s centralized sanitary treatment plant. LANL has 87 septic systems that have been permitted. Thirty-five are active, 2 are inactive, 18 are abandoned, and 32 have been bypassed to the centralized sanitary treatment plant. Six systems were identified as having measured concentrations above the screening levels. Of the six systems, four are no longer active and have been abandoned; and two had samples with concentrations that were only marginally above the screening levels. Two additional systems were identified as potentially having measured concentrations above the screening levels and will need to be resampled. Estimates of the measurement and sampling uncertainty were made. The estimated measurement uncertainty was compared to the values reported by the analytical laboratories. The estimated and reported measurement uncertainties tended to agree with one another. Pairs of measurements from duplicate and split samples were compared and found to predominantly agree with one another.

    The summary report by Tom Weaver gives the overall background for the series of IVE (Integrated Verification Experiment) experiments including information on the full set of measurements made. This appendix presents details of the infrasound data for the and discusses certain aspects of a few special experiments. Prior to FY90, the emphasis of the Infrasound Program was on underground nuclear test (UGT) detection and yield estimation. During this time the Infrasound Program was a separate program at Los Alamos, and it was suggested to DOE/OAC that a regional infrasound network be established around NTS. The IVE experiments took place inmore » a time frame that allowed simultaneous testing of possible network sites and examination of propagation in different directions. Whenever possible, infrasound stations were combined with seismic stations so that a large number could be efficiently fielded. The regional infrasound network was not pursued by DOE, as world events began to change the direction of verification toward non-proliferation. Starting in FY90 the infrasound activity became part of the Source Region Program which has a goal of understanding how energy is transported from the UGT to a variety of measurement locations.« less

    As part of the integrated verification experiment (IVE), we deployed a network of hf ionospheric sounders to detect the effects of acoustic waves generated by surface ground motion following underground nuclear tests at the Nevada Test Site. The network sampled up to four geographic locations in the ionosphere from almost directly overhead of the surface ground zero out to a horizontal range of 60 km. We present sample results for four of the IVEs: Misty Echo, Texarkana, Mineral Quarry, and Bexar.

  • A dataset of regional seismograms assembled for a series of Integrated Verification Experiments conducted by the Los Alamos National Laboratory Source Region program is described. The seismic data has been assembled from networks operated by Lawrence Livermore National Laboratory and Sandia National Laboratory. Examples of the data are shown and basic recording characteristics of the network are described. The seismograms are available on a data tape in SAC format upon request.

    A soil sampling and analysis program is the most direct means of determining the concentration, inventory, and distribution of radionuclides and radioactivity in the environment within and around nuclear facilities. This report summarizes and evaluates the concentrations of {sup 3}H, {sup 137}Cs, {sup 238}Pu, {sup 239,240}Pu, {sup 241}Am, {sup 90}Sr, total uranium, and gross alpha, beta, and gamma activity in soils collected from Los Alamos National Laboratory (LANL), perimeter, and regional (background) areas over a 21-year period (1974 through 1994). Also, trends in radionuclide concentrations and radioactivity over time and the total effective dose equivalent (TEDE) were determined for eachmore » site. The upper-limit regional background concentration (95% upper-confidence level) for each radionuclide and level of radioactivity were as follows: {sup 3}H (6.34 pCi mL{sup {minus}1}), {sup 137}Cs (1.13 pCi dry g{sup {minus}1}), {sup 238}Pu (0.008 pCi dry g{sup {minus}1}), {sup 239,240}Pu (0.028 pCi dry g{sup {minus}1}), {sup 241}Am (0.208 pCi dry g{sup {minus}1}), {sup 90}Sr (0.82 pCi dry g{sup {minus}1}), total uranium (4.05 {micro}g dry g{sup {minus}1}); and gross alpha (35.24 pCi dry g{sup {minus}1}), beta (13.62 pCi dry g{sup {minus}1}), and gamma (7.33 pCi dry g{sup {minus}1}) activity. Based on the average over the years, most LANL and perimeter soils contained three or more radionuclides and/or gross radioactive that were significantly higher in concentration (p < 0.05) than regional background. The net dose (TEDE minus background) for residents living on-site at LANL or along its perimeter ranged from {minus}0.3 mrem y{sup {minus}1} (east of TA-54) to 3.8 mrem y{sup {minus}1} (east of Ta-53) and from {minus}0.4 mrem y{sup {minus}1} (White Rock) to 3.6 mrem yy{sup {minus}1} (west of LANL on Forest Service land across from TA-8GT site).« less

    Surface transport of waste residues was investigated at Waste Disposal Area G by sampling soil, air, and water at the site surface. Sampling locations for soil and vegetation were deliberately selected at (1) the most likely points of occurrence of radionuclides or (2) likely points of occurrence with theoretically the highest concentrations of radionuclides if radionuclides were transported from burial to the site surface. Data obtained from this reconnaissance showed that /sup 3/H, /sup 239/ /sup 240/Pu, and ..gamma..-emitting radionuclide concentrations occasionally increase modestly above regional background levels. The data also indicated that /sup 3/H is migrating from waste repositories,more » whereas /sup 239/ /sup 240/Pu and ..gamma..-emitters are not migrating out of repositories. The latter were probably deposited on the surface by occasional spills during disposal operations or as a result of surface storage and holding practices. However, all radionuclide concentractions remain orders of magnitude below applicable standards and guides used to assure that their concentrations in environmental media would not lead to unnecessary or unsafe levels of exposure to the public.« less
