Abstract
As part of a program to surley low levels of radioactivity in the marine environment of the southern hemisphere, we have studied the distribution and uptake of131I found in the subtidal kelp Ecklonia radiata, on the west coast of Australia. Concentrations of 5 to 75 fCi/g of131I exist in this species over a considerable distance along the coast. We have characterized the principal source of the131I and found a general temporal correlation between the amount of radioiodine discharged from sewer outfalls and its concentration in kelp. Transplant experiments have enabled us to estimate uptake and depuration rates, and our results are consistent with laboratory measurements made by others.
