December 5, 2001 — WOBURN, MA — Independent tests confirm that the Xenon SteriPulse system effectively destroys in a one second exposure, millions of spores of selected Anthrax surrogates.

Tufts University School of Medicine and Toxicon, a nationally recognized commercial testing laboratory, used the SteriPulse XL 3000 in their experiments and found that successive pulses of ultraviolet light, administered over only one second, completely eradicated all bacteria.

The successful validation tests on the Bacillus anthracis surrogate Bacillus subtilis, were conducted by Dr. Abraham Sonenshein, Microbiologist at the Tufts University School of Medicine.

“Using this high-energy pulsed UV system, the complete killing of 10-100 million spores was achieved by the SteriPulseXL 3000 in Dr. Sonenshein’s tests,” said Jeffrey Gelfand of the Mass general Hospital Infectious Disease Unit.

Xenon’s SteriPulse XL system delivers extremely intense UV light pulses in a very short duration and performs an environmental sweep over the object in question. The system has been designed extensively to destroy bacteria, virus, molds, spores, etc. The degree of microbial destruction is a function of both the time and intensity of the photo-radiation to which a given microorganism is exposed

To date, Xenon has received numerous inquiries from governmental and commercial mailrooms as well as companies dealing with the treatment of environmental issues in various federal buildings.
