-4long range studies employing sophisticated techniques in the more heaviliy contaminated areas of the atoll. Radiological survey data on the distribution of radioactivity in the environs and in life forms will permit quantification of the above statements and the identification of any problem areas that might exist as a result of special physical, chemical or biological concentration processes. However, it appears highly unlikely that these processes would occur to the extent of producing large effects on any significant portion of the flora and fauna of the atoll.
