Sažetak
This paper presents a new method for calculating the effective dose of 226Ra regularly ingested with drinking water over a long period of time. The method is based on the assessment of cumulated 226Ra activity in the fraction retained in the whole body at time t (in days) after intake [so called m(t) value]. For modelling, simulation, and visualisation of the continuous intake of 226Ra by drinking water, we used the Simulink® program package integrated with the Matlab®. The dose assessment was performed for 226Ra activities of 5 mBq L-1, 50 mBq L-1, 1000 mBq L-1 and 5000 mBq L-1. The results suggest that 226Ra activities above 1000 mBq L-1 produce effective doses which are below the recommended maximum. However, the potential effect of 226Ra activities of this extent is still unknown in children.
