IL/12/47  W.J. Batterfield    "These documents have been reviewed
                              by the Insurance Claims Section and
                              no objections are made to their
                              publication from the Insurance
                              Claims viewpoint."

3/19/47   Maj. B.M. Brundage  "We are also in agreement with
                              Public Relations that the paper
                              'Uranium Excretion Studies'  should
                              not be declassified because of the
                              fact that it is pointed out that
                              certain Commission personnel were
                              hospitalized for excretion tests."

3/18/47   G.O. Robinson       "This office feels that release of
          Public Relations    'Uranium Excretion Studies' would be
                              unwise because it reflects
                              hospitalization of certain personnel
                              and possibly could have an effect on
                              certain lawsuits."
