Abstract:
A powder of Anthrax spores or other microbial contamination in a series of conveyed envelopes or banknotes (2) are deactivated by pulses of energy. Preferably, the deactivation occurs in the normal processing and sorting of mail or paper currency. The pulsed energy is in the form of low kinetic energy (under 500 keV) enull beams (12) or x-rays which are pulsed in coordination with the movement of mail in the mail handling equipment or the movement of banknotes into or out of an automatic teller machine. The treatment of either mail or currency is done under nearly adiabatic conditions.
