[en]A given fallout of radiocaesium will be distributed and taken up by biota differently in various types of lakes. Thus, lakes have different ''sensitivities'' to radiocesium. Important environmental factors regulating the biouptake are the water retention time and the K-concentration. Several practically useful and ecologically relevant methods exist to remediate lakes, e.g., liming, potash treatment and fertilization of low-productive lakes. The basic aim of this paper (which is a brief version of paper I) is to use the VAMP model, first to illustrate the fact that different lakes have different ''sensitivities'', and then to simulate the effects of alternative remedial methods. The VAMP model has been validated against an extensive set of data from seven European lakes. It has been shown that the VAMP model yields just as good predictions as parallel sets of empirical data, and this is as good as any model can do (II). The main objective of the model is to predict radiocesium in predatory fish (used for human consumption) and in lake water (used for irrigation, drinking water, etc.)
