As to the question of whether equivalent dose reductions (equivalent to reductions obtained through medification of the dtet) could be obtatned through removal of contaminated soil, the Task Group holds the opinion that some reduction is possible. However, the magnitude of this reduction is uncertain and can only be determined reliably through measurement cf the radionuclide content of the important food items such as pandanus and breadfruit grown in the modified condition. This would require a research effort to grow test plantings of the various food crops in the soil removal and replacement areas using various fertilizers and trace minerals, and analysis of radionuclide content of the fruit produced. There is the possibility that radioactivity in the fruit could be reliably predicted from analysis of stems and leaves of young and as yet unproductive plants. a ’ ag Pt pr ranted L 1 additional study. sages This would require bean nla tote heageget Wb ae Considering,the_tine-wequtced<foremir SE0dLesaE ae ab.
