Acute Radiotoxicity of (BA-LA)140 in Rats and Mice : Part I. Preparation and Administration of the Emitters
Barium 140 and its daughter, lanthanum 140, were obtained from uranium fission. The composition of the solutions used in animal studies is given a procedure for delivering toxic doses to small animals and methods for preparing animal tissues for radioactivity measurements are described.

Acute Radiotoxicity of (Ha-La)140 for Rats and Mice. Part III. Effects of Height and Food Intake of Animals Treated with (Ha-La)140
In the (Ha-La)140 experiments mice and rats were injected intraperitonially with toxic doses of radiobarium. The weight curves indicate that there was definite retardation of growth in mice and 2.25 uc/g and in rats at 1.98 uc/g.

The Clinical Physiology of Dogs Exposed to Single Total-Body Doses of X-Rays
A rational approach to therapy for irradiation damage must be based upon knowledge of the nature of the damage. This study of clinical physiology of dogs exposed to singe doses of total body X-radiation was undertaken to provide such a basis for therapy and to provide a basis for descriptions of the effects of specific project hazards.

Collision Mechanics and Energy Angle Nomography
The general reaction of interest in nuclear physics is that due to N1 colliding with N2 and producing N3 and N4 with reaction energy Q. It is shown how the energies of N3 and N4 can be obrtained at any angle from a nomograph simply constructed of semicircles.

Observations on the Preparation of the Tribromide and Triiodide of Uranium
Uranium Tribromide has been prepared both by the reduction of the tetrabromide with hydrogen at 600-700° C, and by direct union of uranium and bromine at about 580°C. An attempt to prepare the triiodide of uranium by the latter method was unsuccessful
