(The date on land crabs shown in Table Cne are from the Talend of Kabelle which is more heavily contaminated then the Island of Romgelap). However, if crabs were elicineated from the diet, the intake might be about 107 Sunshine Units. Farther, elimination or restrictionof the consumption of pandamis would reduce the strontimm-90 iuteke to well under 100 Sunshine Units. 13- There is save doubt concerning the correct strontium-<0 activity in the land crave since they are higher thon for previous surveys which is camtrary”to ell other data. -Glerigy this point. ™ any event these land crabs are froa the Inland « § §0020449 Additional surveys should «
