C c. -2- < The location of all disposal areas (inside or outside the lagoon) will be recorded on an appropriate chart for future reference. If a plutonium contaminated area is found, the degree of contami- nation will be determined by the AEC Radiological Safety Advisor, and he will make appropriate recommendations to the Commander. On Nam, where people will not be living continuously in the near future, general radiation levels are now in the 0.1 to 0.2 mR/hr range. In this case, no attempt to decontaminate the ground surface by removal of large quantities of top soil should be attempted since this would injure the island for future agricultural use. A careful search for loose radioactive scrap, however, shall be made. Scrap metal on islets adjacent to any ground zero and all campsites and work areas will also be monitored, Materials which need to be disposed of and which exceed radiological criteria established by guidelines will be disposed of in any one of the designated areas. In some cases, bunkers or other structures near a former ground zero contain concrete with activated aggregate or reinforcing steel which have radiation levels above 0.1 mR/hr. Depending on the level of radiation and planned use for the individual structures, several recourses are available. These include cutting out of the contaminated or activated portion, complete removal of the structure, cementing over the reinforcing steel, etc. The AEC Radiological Safety Advisor will make appropriate recommendations to the Atoll Commander. Scrap containing no induced radioactivity, such as towers and other materials on Bikini and Eneu and similar materials on other islands, SR ar Me mac Hy requires no special consideration from a radiological viewpoint and is therefore not covered by these guidelines.
