Project 2.6a -- Chemical, Physical, and Radiochemical Characteristi« Ss of the Contaminant Agency: Naval Radiological Defense Laboratory (NRDL) Operations: Analysis of samples provided by Projects 2.5a and q.4, with laboratory operations at NRDL and probably Parry. Shots: All. Radiation Exposure Potential: Likely for any personnel involvec in field work and perhaps some potential for those performing analysis later. Staffing: Fifteen were associated with this project, but exposu are not given for one civilian and one military. res Exposures for the others (13 civilians from NRDL) are given in Table 19. Project Report: Reference 55. Project 2.6b -~ Radiochemical Analysis of Fallout Agency: Army Chemical Center Operations: (ACC) Samplers on eight islands at Bikini Atoll, two isl ds at Enewetak Atoll, Unibor in the Enewetak Lagoon, and on a barge c lected data for analysis in the laboratory trailer at Parry. is Much of was done by Project 2.5b personnel who normally employed helico Shots: BRAVO, ROMEO, KOON, UNION Radiation Exposure Potential: (Bikini); NECTAR ers. (Enewetak). High during recovery operations; oder- ate during analysis. Staffing: Six were associated with this project, three civilia three military, all from ACC. Project Report: Reference 56.
