[Aspects of long-term ingestion of contaminated food by cattle and game]. / Aspekty dlouhotrvající ingesce kontaminované potravy u hovezího dobytka a zvere.

A radioactive contamination monitoring system of the Czechoslovak Federal Ministry of Agriculture and Food is described, including measuring and calibration methods and the monitoring results. Cesium contamination higher than the international derived intervention level was found only in game. The reasons were as follows: uncultivated green fields, forest herbage and needle-leaves are sufficient sources of game contamination; there exist evident differences between continuous ingestion of contaminated or mixed feed with respect to the cesium contamination of tissues.
