Description
In almost all samples, the ratio found between organically bonded tritium (OGT) and tritiated water in the biosphere (HTO) was R=OGT/HTO > 1. Such R values of the samples taken in the environment of Karlsruhe Nuclear Research Centre cannot be explained by a balanced model of the behaviour of tritium in plants. This is why the dynamic behaviour of T is currently systematically studied in a tree standing on the premises of the nuclear research centre. The OGT values of the leaves in the vegetation period of 1981 rose from 1.4 +- 0.22 pCi/ml of oxidation water in the buds to 4.6 +- 0.35 pCi/ml during the leaf-shedding period. The largest ratio found was R=8.2. (orig./HP)
Abstract (German)
In fast allen bisher untersuchten Proben wurde ein Verhaeltnis R=[OGT]/[HTO] von groesser als 1 gefunden. Diese R-Werte in den Umgebungsproben lassen sich durch ein Gleichgewichts-Modell fuer das Verhalten von T in Pflanzen nicht erklaeren. Aus diesem Grunde wird z.Z. das dynamische Verhalten des T in einem Baum auf dem KfK-Gelaende systematisch untersucht. Die OGT-Werte der Blaetter in der Vegetationsperiode 1981 stiegen von 1,4 +- 0,22 pCi/ml Oxidationswasser in den Knospen bis 4,6 +- 0,35 pCi/ml beim Laubfall an. Das groesste Verhaeltnis wurde mit R=8,2 ermittelt. (orig./HP)Additional details
