[Relations between the contamination of beef and cow's milk with radiocesium]

The paper presents the results of an experimental investigation designed to study the trend of the contamination by radiocesium of milk and meat of cows: (1) under conditions of a single contamination of the pasture. (2) under conditions of a continuous ingestion corresponding to the case of a constant contamination of the pasture. The knowledge of the evolution in the course of time of the relation between the activities of meat and milk and of its dependence on the nature of the different organs and the age of the animals should make more easy the survey of the contamination of the environment and allow to decide on possible countermeasures to be taken in the case of an accident.
