to compared the bioaccumulation of several actinide elements by plants and rats from a contaminated pond shoreline, concentrations of **2**3**3u, **2**3**8u, **2**4**1am, **2**4**4cm, and **2**3**9pu were measured radiochemically in shoreline sediment, emergent macrophytes, cotton rats and soil and fescue grass collected 3-5 m away from the shoreline, of a former low-level liquid radioactive waste pond. actinide concentrations in shoreline plants, expressed as geometric means, were 2-150 times greater than in fescue collected away from the pond shoreline. concentrations of actinides in rat gastrointestinal tracts were greater than or equal to concentrations in shoreline plants. an order of relative uptake of actinides is given in the paper. 22 refs
