The Amchitka Radiobiological Program began in 1970 and is a continuing program to collect biological and environmental samples for radiometric analyses. This report is an account of the program for calendar year 1978. Results of analyses for samples collected in August 1978 have been added to the tables of Seymour and Johnson (1978) which summarize the Amchitka program from 1970 to 1977 and include analyses for: (1) gamma-emitting radionuclides in freshwater, birds, lichens, marine algae, marine invertebrates, fish, aufwuchs, and freshwater moss and plants; (2) strontium-90 (/sup 90/Sr) in rats, birds, and soil; (3) /sup 239/, /sup 240/Pu in sand, soil, marine algae, and fish; and (4) tritium (/sup 3/H) in seawater, freshwater, and biological organisms. Monitoring of background radiation with survey instruments was added to the Laboratory's program in 1974, and the results of the five annual surveys since that date are included in this report. Conclusions from the results of the recent analyses are a reiteration of the results stated in Nelson and Seymour (1975a); namely, (1) no new radionuclides are present; (2) the most abundant radionuclides are naturally occurring beryllium-7 (/sup 7/Be) and potassium-40 (/sup 40/K); (3) the trace quantities of fission products and induced radionuclides are from world fallout; and (4) a trace of /sup 3/H contamination remains in some Long Shot ponds, as previously reported. It is concluded that there were no radionuclides of Milrow or Cannikin origin in the water, plants, or animals of Amchitka Island.
