摘要:
The experiment was performed on 192 Wistar rats irradiated with 154.5 mC kg−1. Therefore, the animals were divided into 5 groups and were treated as follows: group I, controls, with Cs-137; groups II and III with Cs-137 followed by 2-fold administration of ferric ferrocyanide (FF) and ammonium ferric-cyanoferrate (AFCF), respectively; groups IV and V with Cs-137 followed by 6-fold and 10-fold administration of FF and AFCF, respectively. Organ and muscle (16 samples) concentrations of Cs-137 in groups I–III were measured on days 1, 3, 5 and 7, and those of groups IV – V on day 7 after the contamination. The results indicated that in rats contaminated internally with Cs-137 one day post irradiation 2-fold treatment with FF and AFCF in the day resulted in a similar and significant decrease of Cs-137, whereas manyfold treatment (6× or 10×) with these agents did not increase their decontamination effectiveness.
