Collaborating with the Defense Community to Research Chemical, Biological, and Radiological Threats

LRRI offers considerable chemical, biological, radiological and nuclear (CBRN) research capabilities to the defense community.  LRRI has conducted studies for over 40 years with some of the most hazardous materials that can be encountered. Our scientists are experienced in computer simulation, laboratory experiments, field studies, and risk analysis relative to CBRN threats. 


We have expertise in handling a broad range of airborne materials, including:

  • Powders
  • Fibers
  • Toxic chemicals
  • Radionuclides
  • Bioaerosols

As one of the few designated ABSL-3 labs in the nation capable of conducting Good Laboratory Practice research, LRRI has extensive ABSL-3 animal exposure facilities that are available for collaborative or contract work with qualified entities.  LRRI provides expert assistance to designers, contractors, commissioning agents, and owners in the development and operation of biocontainment facilities.

The Hazardous Materials Chemistry and Exposure Laboratory is one of the few facilities in the nation with the specialized equipment and security to handle highly toxic and hazardous chemical agents used in animal exposures. LRRI is widely known for our capabilities in radiation dosimetry and toxicology, with a countermeasures core facility for testing and developing therapeutics against inhaled radioactive compounds. A newly acquired LINAC enables us to perform large-animal whole-body external exposures.
