Peace and Security

“Prevent what we cannot cure.


In the 1960’s, PSR helped end atmospheric nuclear testing by documenting the presence of strontium 90 — a radioactive by-product of nuclear tests — in children’s deciduous teeth. In the following decades, our efforts to educate the public about the public health and environmental dangers of nuclear war and weapons grew into an international movement.

PSR-LA promotes diplomatic solutions to international conflicts to ensure that policy makers and the public have accurate and timely information about the public health consequences of national security decisions.

We assert a strong medical voice against the development and use of nuclear weapons and work to address the medical and psychological consequences of war on civilian populations and American troops.
