The energy dependence of film blackening is discussed and shown graphically. The exposure range of films is discussed, and blackening is plotted vs exposure for DuPont No. 502, and for the less sensitive DuPont No. 351. A plan is then described for monitoring radiation exposure to workers by requiring the worker to carry an x-ray film of dental packet size in a badge designed for the purpose. (LEW)

This letter was written in 1944 and applies to the amount of radiation a person could be subjected to under emergency, wartime conditions. Mr. Stone recommends to Dr. Norwood that no man should be ordered to expose himself to more than a tolerance dose (0.1r in a 24 hr period) except in the case of an extreme emergency in which time is of the essence. And that before any man is asked to exceed tolerance that a radiation trained physician be called in for consultation. His recommendations to said physician are that: (a) a single exposure of 1r would cause no harm and could be repeated at long intervals, (b) an exposure of 5 to 10r would produce loss of appetite and nausea and would increase the chances of genetic change but would cause no clinically detectable changes after the incident, (C) an exposure of 25r would do the same as (b) but with greater probability -- he would be personally willing to take a 25r exposure to accomplish an extremely important job, (4) in general keep exposures well below tolerance, (5) due to the genetic effects, women of childbearing age and younger men should be subjected to none and …

The temperature coefficient of eta has been measured with the thermal column of the Argonne pile using uranium foils of different isotopic ratios. The temperature change was effected by filtering neutrons through silver. The measured fractional change per degree centigrade is [formula].

Bi-Pb eutectic and pure Bi penetration of graphites of various densities under 300 degrees C and pressures up to 20 psi was found be of the order of magnitude of 1.0 g/cm(2) and was uniform throughout the graphite. Bi was absorbed less than the eutectic but the oxidation rate of Bi would be prohibitive. There was heavy nitriding in N atmospheres with the Bi and the eutectic.

Report presenting flight measurements of the pressures on the horizontal tail surfaces of a typical propeller-driven pursuit airplane during stalled pull-outs at high Mach number. Unit loads measured on the stabilizer at safe maneuvering limits were not only considerably in excess of the design unit loads, but also occurred in a direction opposite to the design loads. Revision of the tail-load design requirements and manner of specifying safe maneuverability limits to pilots appears necessary.

An analysis has been made of the drag losses in airplane flight of cross-flow plate and tubular intercoolers to determine the cooling-air weight flow and pressure drop that give a minimum drag loss for any given cooling effectiveness and, thus, a maximum power-plant net gain due to charge-air cooling. The drag losses considered in this analysis are those due to (1) the extra drag imposed on the airplane by the weight of the intercooler, its duct, and its supports and (2) the drag sustained by the cooling air in flowing through the intercooler and its duct. The investigation covers a range of conditions of altitude, airspeed, lift-drag ratio, supercharger-pressure ratio, and supercharger adiabatic efficiency. The optimum values of cooling air pressure drop and weight flow ratio are tabulated. Curves are presented to illustrate the results of the analysis.

The following report is the result of a reconnaissance of the black shales of the Eastern United States in the summer of 1944. The purpose of this reconnaissance was to determine the radioactivity of the shales, specifically for uranium and thorium.

"The purpose of this manual is three-fold: a. To give you those basic principles of watermanship that will enable you to meet with confidence any emergency that may arise. b. To teach you certain fundamental practices used during small landing-craft operations. c. To show you how to swim small lakes or rivers under combat conditions."
