A two-compartment model of tritium metabolism in human body has been used for dosimetry
calculations based on tritium concentrations in urine. In stationary conditions the
measured background tritium activity in urine was 4.9 ± 0.5 Bq-1
corresponding to a dose of 0.100 ± 0.007 mSvy-1.
To exceed the allowed limit for occupational exposure of 50 mSvy-1, the maximum
concentration of tritium in urine following acute exposure to tritium should be above 60
MBql-1.
