iv, 25 pages plus four sheets of charts. Footnotes. Part one contains Abstract, Summary, Administrative Information, Methods, Table, and Figures. Part two contains tables, graphs, summary. references. Marked "Internal Use Only Not For External Distribution" Unclassified. Cover has stamps and markings. Donald J. Kimeldorf stamped on front cover--this was one of the author's copy. Stamp on page 1 also. Part 1 of this report describes a series of experiments in which partial-body exposure to doses of X rays from 200 to 500 r was used to study the previously reported X irradiation. In the study summarized in Part 2 of this report, post-irradiation administration of homologous bone marrow suspension was employed to test the hypothesis that the decrease in volitional activity performed during the 2nd and 3rd weeks related to a hematopoietic deficiency. It appears that hematopoietic injury is the mediating process involved in this performance decrement.
