Abstract

Numerous physical, chemical and biological processes influence the distribution of radioactive materials and their return to man. These include vertical and horizontal advection, turbulent diffusion, precipitation and sedimentation, uptake concentration, and transport by organisms, and transfer to man through his food from the sea. Research is urgently needed on the flushing characteristics of typical harbours, estuaries and open coastal waters, on diffusion and sedimentation processes in inshore waters, and on the passage of radioactive elements through the food web in this portion of the sea. Research is needed to delineate present and potential fishing areas, and non-fishing areas, by basic studies of biological productivity and other means. Studies are also required to determine rates of transfer of radioactive materials between areas by horizontal advection and turbulent diffusion, rates of dilution by diffusion, sedimentation, and vertical transport, and rates of uptake and transfer by the biota. Research is required on efficient means of monitoring waste disposal areas. The ability of certain organisms selectively to concentrate particular elements offers a possible economical basis of monitoring radioactive wastes in the sea at very low concentrations. Specific research proposals have been recently developed by several groups of oceanographers in the United States. These are  More>>

(author) [French] De nombreux processus physiques, chimiques et biologiques influent sur la repartition des matieres radioactives et sur leur retour a l'homme. Parmi ces processus, il y a notamment l'amenee verticale et horizontale, la diffusion turbulente, la precipitation et la sedimentation, l'entrainement, la concentration et le transport par des organismes, et leur transfert a l'homme par les aliments qu'il retire de la mer. Des recherches s'imposent d'urgence sur les caracteristiques de curage des eaux dans les ports, estuaires et rades foraines typiques, sur les processus de diffusion et de sedimentation dans les eaux proches du rivage et sur le passage des elements radioactifs tout le long de la chaine alimentaire dans cette partie de la mer. Il faut entreprendre des recherches pour delimiter les zones de peche presentes et eventuelles et les zones ou la peche ne se fait pas, en procedant a des etudes fondamentales sur la productivite biologique ou en recourant a d'autres moyens. Des etudes sont egalement necessaires pour determiner les taux de transfert de matieres radioactives entre les diverses zones par amenee hori-zontale et par diffusion turbulente, les taux de dilution par diffusion, sedimentation et transport vertical, et les taux d'entrainement et de transfert par les organismes. Une recherche s'impose en ce qui concerne les moyens efficaces de controle des zones d'evacuation des dechets. Certains organismes sont capables de concentrer selectivement des elements determines ;1 cette capacite constitue une base economique eventuelle pour le controle des dechets radioactifs existant dans la mer a des concentrations extremement faibles. Des propositions precises de recherche ont ete recemment mises au point par plusieurs groupes d'oceanographes aux Etats-Unis. Ces propositions ont ete resumees en meme temps que les estimations de. depenses y afferentes. (author) [Spanish] Numerosos son los procesos fisicos, quimicos y biologicos que influyen en la forma en que las sustancias radiactivas se distribuyen y vuelven al hombre. Entre ellos figuran la conveccion vertical y horizontal; la difusion turbulenta; la precipitacion y sedimentacion; la captacion, concentracion y transporte de los materiales radiactivos por organismos, y su paso al hombre por ingestion de alimentos de origen marino. Hay que estudiar urgentemente las caracteristicas del flujo y reflujo de las aguas en puertos tipicos, estuarios y aguas costeras abiertas ; los procesos de difusion y sedimentacion en las aguas costeras, y el paso de los elementos radiactivos a traves de la cadena alimenticia que se encuentra en esta parte del mar. Es necesario efectuar investigaciones para poder delimitar las zonas de pesca presentes y futuras, y las zonas en que la pesca no es posible, mediante estudios basicos sobre la productividad biologica, etc. Tambien es preciso realizar estudios para determinar la velocidad de traslado de las sustancias radiactivas de una zona a otra por conveccion horizontal y por difusion turbulenta; la velocidad de dilucion por difusion, sedimentacion y transporte vertical, y la velocidad de captacion y transmision por los organismos vivos. Es necesario realizar investigaciones sobre los medios mas eficaces para someter a monitoraje las zonas de evacuacion de desechos. Algunos organismos pueden concentrar selectivamente determinados elementos; esto ofrece la posibilidad de efectuar, en condiciones economicas, jel monitoraje de desechos radiactivos de baja concentracion eliminados en el mar. Varios grupos de oceanografos de los Estados Unidos han propuesto recientemente algunos trabajos especificos de investigacion cuyo resumen aparece en esta memoria, junto con un calculo de su costo.
