Abstract

Research on the sorption of radioisotopes under natural conditions employing the controlled filtration process was performed. Radioisotopes were introduced into the solution as soon as filtration had become steady and the process continued for four months. Soil samples were then taken by drilling at different depths and analysed to determine their radioisotope content. Diffusion of radioisotopes was observed at depths of up to 10 m; two distinct boundaries of soil-activity decrease were ascertained: at the surface of the site and at the depth of the solution filtration front. In addition, the radiostrontium absorption by natural sorbents, principally pure minerals widely distributed in soils and subsoils, was investigated separately. The presence of calcium ions, even in small quantities, sharply reduces the degree of radiostrontium sorption. However, other conditions being equal, strontium may be absorbed to a greater extent than calcium, according to the composition of the sorbent. The field investigations of radiostrontium sorption and migration showed that when filtering radioactive solutions two possible variants have to be taken into account. In the first case the solutions are discharged into soil unaffected by any flow of ground water. In this situation the radiostrontium is retained by the soil. In the second case,  More>>

Radioisotopes were introduced into the solution as soon as filtration had become steady and the process continued for four months.

In addition, the radiostrontium absorption by natural sorbents, principally pure minerals widely distributed in soils and subsoils, was investigated separately. The presence of calcium ions, even in small quantities, sharply reduces the degree of radiostrontium sorption. However, other conditions being equal, strontium may be absorbed to a greater extent than calcium, according to the composition of the sorbent. The field investigations of radiostrontium sorption and migration showed that when filtering radioactive solutions two possible variants have to be taken into account. In the first case the solutions are discharged into soil unaffected by any flow of ground water. In this situation the radiostrontium is retained by the soil. In the second case, the radioisotopes proceed directly into the water-bearing horizon. The radiostrontium will then migrate with the ground water flow and through the soil and this migration will be further affected by the sorption and desorption processes occurring. The experiments performed demonstrate the ease with which long-lived radioisotopes migrate under natural conditions and call attention to the need for thorough study of ground water problems in connexion with various methods of disposing of radioactive waste into ground. (author) [French] En declenchant un processus de filtration, il a ete possible d'etudier l'absorption des elements radioactifs dans la nature. Des que la filtration est devenue constante, on a commence a ajouter a la solution des elements radioactifs ; le processus a dure quatre mois. Des forages consecutifs ont permis de recueillir, a des profondeurs differentes, des echantillons du sol qui ont ete analyses en vue de determiner leur teneur en radioelements. Il a ete constate que la diffusion des isotopes radioactifs atteignait une profondeur d'au moins dix metres, et qu'il existait deux zones nettement determinees ou la radioactivite du sol etait plus faible : l'une a la surface du terrain et l'autre au fond atteint par la solution filtree. On a procede en outre a une etude separee de l'absorption du radio-strontium par des absorbants naturels, principalement par les mineraux purs largement repandus dans les diverses terrains. La presence de certaines quantites, meme petites, d'ions de calcium reduit sensiblement le taux d'absorption du radiostrontium. Cependant, en raison de leur composition - toutes les autres conditions etant egales - certaines substances peuvent absorber le strontium en quantites plus elevees que le calcium. La verification sur place de l'absorption et de la migration du radiostrontium a montre que la filtration des solutions radioactives peut se presenter sous deux formes differentes. Elle prend la premiere lorsque les solutions sont deversees dans des terrains sans a l'action du flux d'eau. Le radiostrontium est alors retenu par les terrains. La deuxieme se presente quand les elements radioactifs penetrent directement dans les couches aquiferes. Dans ce cas le radiostrontium est entraine par les courants souterrains et penetre egalement dans les terrains ou sa migration s'accompagne du processus d'absorption et de desorption. (author) [Spanish] Provocando un proceso de filtracion se ha podido estudiar la absorcion de los elementos radiactivos en la naturaleza. En cuanto se inicio la filtracion se anadieron elementos radicativos a la solucion; el proceso se prolongo durante cuatro meses. Despues, mediante una serie de perforaciones consecutivas, se extrajeron muestras de tierra recogidas a distintas profundidades y se analizaron para determinar su contenido de elementos radiactivos. Se pudo comprobar que la difusion de los radioisotopos alcanzaba una profundidad de diez metros por lo menos y que habia dos zonas perfectamente delimitadas en las que la radiactividad del terreno era menor: la capa superficial y el fondo de la zona de filtracion. Tambien se ha estudiado la absorcion del radioestroncio por los absorbentes naturales, especialmente por los minerales puros muy difundidos por las diversas formaciones geologicas. La presencia de iones de calcio, incluso en pequena cantidad, reduce considerablemente el grado de absorcion del radioestroncio. Sin embargo, segun su composicion -siempre que las demas condiciones sean iguales - otras sustancias pueden absorber el estroncio en cantidades mas elevadas que el calcio. Verificando in situ la absorcion y la migracion del radioestroncio se ha podido comprobar que la filtracion de las soluciones radiactivas puede revestir dos formas diferentes. En el primer caso, si las soluciones se vierten en terrenos que resisten a la accion de las corrientes de agua, el radioestroncio queda retenido por las rocas. En el segundo caso, cuando los elementos radiactivos penetran directamente en las capas acuiferas, el radioestroncio es arrastrado por las corrientes subterraneas y penetra tambien en las rocas, en las que su migracion se combina con un proceso de absorcion y desorcion. (author) [Russian] Ispol'zuja process ustanovivshejsja fil'tracii, bylo provedeno issledovanie sorbcii radiojelementov v prirodnyh uslovijah. S momenta ustanovlenija fil'tracii v rastvor vvodilis' radiojelementy, i process prodolzhalsja v techenie 4h mesjacev. Zatem posredstvom burenija otbiralis' proby grunta s razlichnyh glubin i analizirovalis' na soderzhanie radiojelementov. Rasprostranenie radioizotopov nabljudalos' do glubiny ne menee 10 metrov s dvumja rezkimi granicami umen'shenija radioaktivnosti grunta: v poverhnostnoj chasti i na glubine fronta fil'tracii rastvora. Krome togo, otdel'no izuchalos' pogloshhenie radiostroncija prirodnymi sorbentami, preimushhestvenno chistymi mineralami, shiroko rasprostranennymi v pochvah i gruntah. Prisutstvie dazhe nebol'shih kolichestv ionov kal'cija rezko snizhaet stepen' sorbcii radiostroncija. Odnako v zavisimosti ot sostava sorbenta stroncij, pri prochih ravnyh uslovijah, mozhet pogloshhat'sja v bol'shej stepeni, chem kal'cij. Polevaja proverka sorbcii i migracii radiostroncija pokazala, chto pri fil'tracii radioaktivnyh rastvorov sleduet rassmatrivat' dva vozmozhnyh varianta. Pervyj - rastvory sbrasyvajutsja v grunty, ne podvergajushhiesja vozdejstviju vodnogo potoka. Pri jetom radiostroncij zaderzhivaetsja gruntami. Vtoroj - radiojelementy popadajut neposredstvenno v vodonesushhij gorizont. V jetom sluchae proishodit migracija radiostroncija s potokom gruntovoj vody, a takzhe ego migracija po gruntam s nalozheniem processov sorbcii i desorbcii. (author)}
