The Advisory Committee on Human Radiation Experiments has correctly ar
gued that persons and institutions can sometimes be held responsible f
or actions taken more than a half-century ago, when practices and poli
cies on the use of research subjects were strikingly different. In rea
ching its conclusions, the Committee did not altogether adhere to the
language and commitments of its own ethical framework. In its Final Re
port, the Committee emphasizes judgments of wrongdoing, to the relativ
e neglect of culpability; it discusses mitigating conditions that are
exculpatory, but does not provide a thoroughgoing assessment of either
culpability or exculpation. However, the Committee's shortcomings are
mild in comparison to the deficiencies in the ''Report of the UCSF Ad
Hoc Fact Finding Committee on World War II Human Radiation Experiment
s'' of the University of California at San Francisco. The latter repor
t reaches no significant judgments of either wrongdoing or culpability
. The findings that should have been reached by both committees are di
scussed.
