Abstract

Practices which lead to safe disposal of radioactive wastes permit the return of the wastes to man only at levels below maximum permissible concentrations, and do not prevent the development of resources which in the absence of disposal could make a significant contribution to man's well-being. The design of safe disposal procedures for any selected marine location is at present limited by our knowledge of several parts of the system which is involved in the return of radioactivity from the disposal site to man. Because of our present lack of knowledge, disposal procedures now being considered in the United States contain an unknown amount of ''over-design'' and, although they are believed to be conservative, are not unduly restrictive at present levels of waste generation. A better understanding of (a) turbulent mixing processes in the oceans, (b) the physical and chemical states of waste-product elements when in equilibrium with sea-water, and (c) the interaction of waste-product elements with the marine biota, their biological half-life, and the extent of their concentration or rejection by marine organisms in all trophic levels, will provide the basis for a more efficient and safer utilization of the marine environment for the disposal of radioactive wastes.

(author) [French] Les pratiques qui assurent une elimination sans danger des dechets radioactifs ne permettent le retour de ces dechets a l'homme qu'a des activites d'un niveau inferieur aux concentrations maxima tolerees et n'empechent pas le developpement de ressources qui, en l'absence de toute elimination, pourraient constituer une contribution importante au bien-etre de l'homme. La mise au point de procedes d'evacuation pour tout endroit choisi de la mer est a present limitee par le niveau de nos connaissances en ce qui concerne plusieurs elements du processus par lequel la radioactivite des dechets retourne vers l'homme. Du fait qu'a l'heure actuelle ces connaissances sont insuffisantes, les procedures d'evacuation que l'on examine aux Etats-Unis sont elaborees pour faire face a un nombre inconnu d'eventalites, et, bien qu'elles soient considerees comme prudentes, elles ne sont pas restrictives outre mesure vu l'activite des dechets produits a l'heure actuelle. L'utilisation plus efficace et moins dangereuse du milieu marin pour l'evacuation des dechets radioactifs ne pourra etre realisee que grace a une connaissance de base plus approfondie: a) des processus de melange turbulent dans les mers; b) des etats physique et chimique des elements composant les dechets lorsqu'ils se trouvent en etat d'equilibre avec l'eau de mer; c) de l'interaction entre les elements de dechets et la faune et flore marines; des taux de concentration ou d'elimination de ces elements par les organismes marins a tous les niveaux trophiques ainsi que de leur periode biologique. (author) [Spanish] Gracias a los procedimientos de evacuacion sin riesgos de desechos radiactivos se consigue que estos lleguen al hombre en un grado de concentracion inferior al maximo admisible, y no se impide el desarrollo de recursos que podrian contribuir en gran medida al bienestar de la humanidad. Actualmente, la preparacion de procedimientos de evacuacion sin riesgos en una zona marina determinada se ve limitada por el escaso conocimiento que poseemos de algunas de las etapas del proceso mediante el cual la radiactividad pasa del lugar de la evacuacion al hombre. A consecuencia de ello, los procedimientos de evacuacion que se estudian en los Estados Unidos de America se caracterizan por un exceso de prudencia y aunque se les considera moderados, no son exageradamente restrictivos con respecto, al nivel actual de acumulacion de desechos. Para llegar a una utilizacion mas eficaz y sin riesgos del mar como lugar de evacuacion de desechos radiactivos sera preciso conocer mejor: a) los procesos de mezcla turbulenta en los oceanos, b) el estado fisico y quimico de los elementos constitutivos de los productos de desecho cuando estan en equilibrio con el agua del mar, y c) la accion reciproca de esos elementos con la fauna y la flora marina, el grado de concentracion o expulsion por organismos marinos en todos los niveles troficos, asi como el periodo biologico de los elementos. (author) [Russian] Praktika, svjazannaja s bezopasnym udaleniem radioaktivnyh othodov, dopuskaet ispol'zovanie chelovekom lish' takih othodov, kotorye imejut aktivnost' nizhe maksimal'no dopustimogo urovnja, i ne prepjatstvuet razvitiju takih resursov, kotorye pri otsutstvii neobhodimosti udalenija radioaktivnosti mogut prinesti cheloveku znachitel'nuju pol'zu. Process bezopasnogo udalenija othodov v ljubom morskom bassejne v nastojashhee vremja ogranichivaetsja nashimi poznanijami nekotoryh storon sistemy, kotoraja vkljuchaet vozvrat radioaktivnyh veshhestv iz mesta zahoronenija obratno v pol'zovanie cheloveka. Iz-za nedostatka neobhodimyh poznanij rassmatrivaemaja v Soedinennyh Shtatah procedura udalenija radioaktivnyh othodov soderzhit mnogo ''raschetov s bol'shim zapasom'' i, hotja jeta procedura schitaetsja konservativnoj, ona ne zrja javljaetsja ogranichitel'noj pri sushhestvujushhem urovne aktivnosti obrabatyvaemyh othodov. Luchshee ponimanie : a) processov turbulentnogo smeshenija v okeanah') fizicheskogo i himicheskogo sostojanija jelementov produktov othodov pri ravnovesii s morskoj vodoj i s) vzaimodejstvija jelementov produktov othoda s podvodnoj biosferoj, rasprostranenija koncentracii ili otrazhenija i biologicheskogo poluraspada jelementov s uchastiem podvodnyh zhivyh organizmov pri vseh troficheskih urovnjah - obespechat osnovu bolee jeffektivnogo i bezopasnogo ispol'zovanija podvodnoj sredy dlja udalenija radioaktivnyh othodov.
