An aerial radiological survey of Technical Area 15 and surroundings, Los Alamos National Laboratory, Los Alamos, New Mexico
An aerial gamma survey of the entire Los Alamos National Laboratory and the adjacent area was flown in September 1982. The data from a part of the survey, Technical Area 15, are presented here. Other parts of the survey data that will complete the presentation will be published in a separate report. The gamma survey data show significant Pa-234m activity which implies U-238 activity above background levels. Concentration isopleths overlaid on aerial photographs of this area indicate the position and extent of this isotope. The inventory of Pa-234m (above background) is probably between 4 and 23 curies, depending on the actual vertical distribution of the Pa-234m in the soil. Isopleth maps of the natural background gamma exposure rates and the total exposure rates (natural plus exposure due to Pa-234m) are included. Implied exposure rates at 1 meter above the ground range from a minimum terrestrial component of 6{mu}R/h to 22{mu}R/h over areas where Pa-234m and the parent, U-238, exist. 1 ref., 5 figs., 3 tabs.
