1. A method for decontaminating a contaminated object, said method comprising:

  • submerging the contaminated object in a cleaning solution contained within a pressurizable container;

    pressurizing the pressurizable container to a predetermined pressure, greater than about 1 atmosphere, so as to pressurize the cleaning solution; and

    vibrating the cleaning solution at an energy density sufficient to produce ultrasonic transient cavitation, the cleaning solution comprising a base solution having a predetermined amount of a transient cavitation-enhancing substance, the transient cavitation-enhancing substance being selected so as to maximize ultrasonic transient cavitation in the cleaning solution, the maximum transient cavitation being a function of the amount of the transient cavitation-enhancing substance, the pressure, and the energy density.
