Seaweeds share properties with the mammalian thyroid and other iodide concentrating organs in that they take up iodide from surrounding seawater and internalise it within cells. The previously demonstrated high iodine concentration within seaweeds prompted a study of accumulation and retention of 125I and its location within the plants. Seaweed discs (1 cm3) cut from members of the red, green and brown phyla which were incubated at 4C in seawater spiked w...
