Abstract The livers and hearts of tana fish collected from the Paclfic Ocean were analyzed for Fe/sup 55/ content as an indication of fall-out radioactivity. The specific activity of the samples, in Feb. 1961, was found to be 82000 dpm/gm of Fe. Values were calculated for the specific activity of oceanic Fe. Measurements were also made of Fe/sup 55/ activity in samples of ocean sediment and rain water from San Diego. Results indicate that the present contribution of atmospheric fall-out is small compared with the total inventory of the ocean, and the activity level of Fe/sup 55/ in the ocean is not great enough to constitute a health hazard.
