Medical Radiobiology Advisory Team (MRAT)


MRAT provides health physics, medical, and radiobiological advice to military and civilian command and control operations worldwide in response to nuclear and radiological incidents requiring a coordinated federal response.

Through "reachback," the deployed team of radiation medicine physicians and senior health physicists can call on the knowledge and skills of radiobiologists, biodosimetrists, and other research professionals at AFRRI as well as those of other Department of Defense (DoD) response teams.


To initiate contact with MRAT, please dial 301.295.0316.
