Table l Details of this survey will be covered in a separate report. FUTURE ACTIVITY PLANS Two high-volume air sampling systems have been obtained and will be placed in the field northeast of the NTIS by the end of the present calendar year. Wind speed and direction will be recorded using National Oceanic and Atmospheric Administration--Air Resources Laboratory instrumentation. Several drainage basins approximately 160 km northeast of the NTS are presently being considered as a second sampling area to investigate concentrating effects of radionuclides in soil. A basin with high sheer walls which act as impingement collectors is being sought. Soil sampling and analysis will continue in order to close existing gaps in the data array. Collecting these samples will require more time than previous samplings due to the remoteness of the sampling area and the difficulties caused by terrain. During the summer of 1975, a study will be executed in the off-NTS area to evaluate the hypothesis that radionuclides accumulate near vegetation where erosion products are deposited. 87
