LA - 13202 - MS Tritium Concentrations in Bees and Honey at Los Alamos National Laboratory : 1979 - 1996 Los Alamos
نویسنده
چکیده
Honeybees are effective monitors of environmental pollution. The objective of this study was to summarize tritium en) concentrations in bees and honey collected from within and around Los Alamos National Laboratory (LANL) over an 18-year period. Based on the long-term average, bees from nine out of eleven hives and honey from six out of eleven hives on LANL lands contained H that was significantly higher (p <0.05) than background. The highest average concentration of H in bees ( 435 pCi mL -t) collected over the years was from LANL's Technical Area (TA) 54-a low-level radioactive waste disposal site (Area G). Similarily, the highest average concentration of H in honey (709 pCi mL") was collected from a hive located near three H storage ponds at LANL TA-53. The average concentrations of H in bees and honey from background hives was 1.0 pCi mL" and 1.5 pCi mL"l, respectively. Although the concentrations of H in bees and honey from most LANL and perimeter (White Rock/Pajarito Acres) areas were significantly higher than background, most areas, with the exception of TA-53 and T A54, generally exhibited decreasing H concentrations over time.
