  The processes of interaction of an aqueous solution of methylene blue (MB)
organic dye ($C_{16}H_{18}N_{3}SCl$ ) with gamma quanta and electrons have been
investigated. A model has been developed, and the passage of electrons with an
energy of 15 MeV through tungsten layers with a thickness of 1...8 mm has been
simulated. A number of experiments were carried out on the basis of the
simulation results. Analysis of the calculated and experimental data showed
that one incident electron destroys 4 times more dye molecules than one
incident gamma-quantum.
