Fundamental Explosivity & How to Deter It
R1-B1

Creation of Tests & Metrics

  • A fundamental method for determining explosivity is needed
    • to screen for potential threats
    • to determine what component ratios are explosive
    • to recognize when a threat has been successfully rendered inert

Adulteration efforts rely on explosive tests being indifferent to sample size. Hence, a new testing protocol must be devised. Purdue is assessing explosivity of ammonium nitrate (AN), while URI is studying hydrogen peroxide (HP) and its mixtures. Metrics for AN mixtures (water-free) are insufficient for inherently aqueous HP mixtures. URI is developing versatile metrics, which perform regardless of physical state or water content.

  • Adulteration of explosive precursors will be attempted

Adulteration requires

  • a thorough understanding of formation & destruction chemistry
  • a “foothold” in the synthetic route used by terrorists
  • a way to quickly test the effect of a particular approach
