-10- NAY Fertilizers would elso be avolied to test vlots of pavaya, benane, coconut, pandsnus fruit,and breaafruit to begin an assessment cf the eFrect of fertilizers upor’ radionuclide uptake. Initial clean-up of litter on otner plots would be started tc assess the possible interruption of tne recycling or radionuclides. Soil samples will also be coilected rom these riots; tre recycling of radionuclide is blocked, it wili be possible to determine the effective removal time of the radionuclides from th errestrial environment 18. EXPECTED RESULTS FY 1975: A. Enewetek Atoll Results for FY 1976 would include the harvesting of crops such as sauash, arrowroot, paveve, banans, end sweet rotato and the direct measurement of radionuclides in focad preducts. From tnece aata and from the ccentinuing analysis of soil/soil- water data, we will be eble to establish concentration Tectcrs for these food products. Effects of fertilicer cn the urteke of radicnuclides will also be assessed. during tnis ristal year. In eadcivicn the erfect cP cleanbead procteaures, clesnusot littey ang mulching; with essentially clean vegetatian from southern islands will be evelnsted tor these Paster-frowing crop srecies. Tre clean-bed procedures and the use of fertilicers will be continued Tor coccnut, pandanus, and breadrruit with expectation of results from these errors in FY 1978. Directly essences racicnuclide concentrations in feca products wili be compared with those used in the assessments in NVO-14C, 3 wnich were besed upon concentrations peodicted trom correlaticn studies. B. Bikini Experiments on test plots with fertilizers end clean-up Procedures ror ri11 be continued to evaluate the effect of asgriculturel vractices on the ur or the recycling of redionuclices by plents. Sarnvles of vapeve “and banana will continue to be collected to determine by Girect measurement the half-time of 31s and SOSr in the unaltereé environment. Measurements of litter-fall and litter-decay rates will be completed furing this fiseal year Coconut should become available during this yeer; the essessments would expand to include tnis significant food product. Pandanus fruit end breadfruit would of course be incluced if available. All data would be factored irto continued assessments of tne rediolosical implication of develcrins various food chains and egricultural practices end in the evalueticn of these scenarios ‘for immediate and long-term use of both Bikini and Enewetek. 19.
