ABSTRACT

Purpose: To determine the estimated capacity of the station cleaning in special units radionuclide therapy based on mathematical modeling of processes of accumulation and exposure to the collapse of liquid radioactive waste.

Material and methods: The simulation is based on solving a system of linear first order differential equations with constant coefficients under certain simplifying assumptions about these processes of accumulation and exposure. For specific numerical simulation results technical and clinical settings for typical units of radionuclide therapy were used.

Results: It is shown that only the presence of a vacuum in the unit special sewage radionuclide therapy ensures that the requirements of regulations on permissible discharge disintegrated liquid radioactive waste into the domestic sewage. Water consumption was hospitalized in “active” patient rooms should not exceed 50 liters / day for 1 person.

Conclusion: Mathematical modeling allows to objectify the processes of dealing with liquid radioactive waste in radionuclide therapy units of radiological clinics in Russia.

Key words: radionuclide therapy, liquid radioactive waste, cleaning station power, mathematical modeling
