Abrasive Blasting for Cleaning Parts

Description: Abstract: A demonstration on August 22, 1945, showed that Alpha or Beta M or K parts, including insulators, can be well cleaned with a pressure-feed abrasive blaster. The abrasive is a slurry of alumina and water mixed with high velocity air in a special feed nozzle. The slurry is continuously recycled.

The Activity Coefficient of Plutonium(IV) Salts in Acidic Solutions

Description: Summary: The activity coefficient of Pu(Cl04)4 was measured in perchloric acid solutions. The procedure used was to measure the extraction of the neutral plutonium(IV)-TTA chelate into benzene-TTA solutions at different perchloric acid concentrations. Equations are presented which show the relation of the extraction coefficients, obtained in the above manner, to the activity coefficient of plutonium(IV) per-chlorate. The activity coefficient of Pu(Cl0~)4 is similar to that of a strong acid, e.… more

Acute Radiotoxicity of Injected Yttrium91

Description: Report describing results of experiments that involved injecting radioactive yttrium into animals: "The excretion, retention, and distribution of the yttrium was measured, and its effect on survival and growth was observed. The average total excretion of Y91 to the time of death (from 76 hours to 24 days) was a little less than 30 per cent of the injected dose" (p. 2).

Alpha Particle Detection and the A. C. Operated Detector "A" (Howler)

Description: Abstract: This discussion concerns the operation, construction, and servicing of an alpha rate meter of medium sensitivity (30,000 alpha particles full scale per minute) and good stability. The instrument is equipped with an oscillator which increases both in frequency and loudness as the alpha activity is increased. The oscillator circuit includes an anticipator which causes a change in frequency depending directly upon the rate of change of alpha activity. Maximum sensitivity is approximately… more
