Protection Of Laboratory Personnel Handling Radioactive Materials

Author: Hempelmann, LH (1947) HERO ID: 1433634

[Less] Graphs are presented showing hematologic data for persons exposed to ionizing radiation. These graphs . . . [More] Graphs are presented showing hematologic data for persons exposed to ionizing radiation. These graphs were previously classified, but were requested to be used as part of a symposium on March 31, 1947, for a presentation on the protection of laboratory personnel handling radioactive materials. The presentation included discussions of tolerance dose for ionizing radiation, methods of calculating radiation dose from radioactive materials taken into the body, and methods used to diagnose early radiation damage. The graphs and charts contained in the present document show counts for platelets, reticulocytes, hemoglobin, red blood cells, lymphocytes with granules, white blood cells, granulocytes, and lymphocytes and monocytes for individuals exposed to ionizing radiation. Also included is data obtained on neutral red bodies in lymphocytes for unexposed persons and those exposed to chronic external radiation, chronic exposure to an unspecified material, and acute external exposure. Additional data is provided on percent of lymphocytes in differential count, absolute number of abnormal lymphocytes, total white blood count, percent of abnormal lymphocytes, and total lymphocyte count in unexposed subjects and persons exposed to gamma rays, alpha emitters, and uranium. Changes in refractile neutral red bodies in lymphocytes after acute radiation exposure are also shown.

Precipitation of Sodium Diuranate from Pitchblende Liquors

Author: Brimm, EO (1947) HERO ID: 3790119

[Less] In the treatment of carnotite concentrates, sodium diuranate was prepared by acidifying tricarbonate . . . [More] In the treatment of carnotite concentrates, sodium diuranate was prepared by acidifying tricarbonate liquors to eliminate carbon dioxide, and then precipitating the sodium salt by the addition of caustic. Direct precipitation of uranium by the addition of caustic to tricarbonate liquors was used when pitchblende ores were processed, because this procedure was more effective in giving a product with a low molybdenum content. Tests of this method in the laboratory and Pilot Plant indicated that low uranium losses (0.2 to 0.3%) would be encountered with typical liquors if 1.7 to 2.0 lbs of caustic were added for every pound of uranosic oxide in solution. Since losses as high as 3% were incurred in plant operations, further work was undertaken, in an effort to reduce the uranium concentration in the waste liquors.

Colorimetric Determination Of Uranium With 1-Ascorbic Acid

Authors: Smith, GG; Orlemann, EF; Smales, AA; Rothenberger, CD; Grimes, WR (1947) HERO ID: 1431961

[Less] A colorimetric method for determining uranium (7440611) was developed and tested. Ascorbic-acid in . . . [More] A colorimetric method for determining uranium (7440611) was developed and tested. Ascorbic-acid in a 10 percent aqueous solution was added to hexavalent uranium in a weak acidic solution. The solution was buffered with ammonium-acetate. The intensity of the yellow color formed was determined by the measurement of the optical density of the solution with a Beckman spectrophotometer. The effects of varying pH from 1 to 11 were studied. The amounts of acid and buffering agent were varied to determine optimum color production. The method was tested on known concentrations of uranium. The effect of foreign ions on color formation was tested with more than 20 ions. About 20 minutes was required for formation of the colored complex. Color intensity was linearly related to uranium concentration up to at least 15 milligrams per milliliter of solution. In the pH range of 4.5 to 4.8, color intensity was independent of pH, but pH of 4.0 prevented iron precipitation. With an increase in ascorbic-acid and a decrease in acetate ion concentration optical density increased. In the absence of acetate ions color was unstable. Chloride, nitrate and perchloride ions had no appreciable effect on color. Anions capable of forming stable complexes with a weak acid solution caused large negative errors dampening the color. Moderate amounts of various elements tested were without effect, though chromium, vanadium, and significant amounts of nickel, zinc, and molybdenum did interfere with the determination. Accuracy of the method was within about 2 percent. The authors conclude that variables must be controlled for high accuracy if the method is to be used.
