“…However, this value is only 7.1 times the 137 Cs concentration in Fontinalis neomexicanus in the nearby transect LS-2 and at the lower end of the wide range of concentration factors (400 to 4,000) reported for algae species collected under both large-scale experimental conditions and field conditions (Williams and Swanson, 1958;Pendleton and Hanson, 1958). Also, this value is within the range of 137 Cs values reported in freshwater aufwuchs and filamentous algae from several streams such as MP 12 Creek and mouth of the North Fork of White Alice Creek during 1972-1979; Table 17). …”
