Validation of environmental transfer models and assessment of the effectiveness of countermeasures using data on (131)I releases from Chernobyl.

The studies undertaken by the (131)I Working Group, part of the International Atomic Energy Agency's EMRAS (Environmental Modelling for Radiation Safety) programme, were focused primarily on evaluating the predictive capability of environmental models. Particular emphasis was placed on applying models to evaluate the effectiveness of countermeasures.

[Testing the differentiatioin medium of Rimler and Schotts for the detection and identification of Aeromonas hydrophila]. / Proverení diferenciacního média podle Rimlera a Shottse pro Záchyt a urcení Aeromonas Hysrophila.

The differentiating medium after Rimler and Shotts (R-S substrate) was tested on 152 strains of the family Enterobacteriaceae, i. e. on the strains of Aeromonas hydrophila, Plesiomonas shigelloides, and Pseudomonas aeruginosa. The accuracy of the prompt identification of the strains of Aeromonas hydrophila in this medium is 94.8 % and the preparation of the substrate is easy. The R-S substrate is recommended to be used in investigating the cause of mortality or morbidity in cold-blooded animals, particularly in reptiles and amphibians, and in mammals which are in contact with water. Bacteriological examinations can also be performed with this medium.
