Bacillus anthracis Spores (anthrax spores)*
*There are conflicting values reported for inactivation of the anthrax spore ranging between 9,400 – 135,000 microwatt-seconds per square centimeter (for 99% inactivation). There are some studies underway to resolve this conflict and we hope to have a reliable value to report within the next several months.
