The Path of Carbon in Photosynthesis

Description: The dark fixation of carbon dioxide by green algae has been investigated and found to be closely related to photosynthesis fixation. By illumination in the absence of carbon dioxide followed by treatment with radioactive carbon dioxide in the dark, the amount fixed has been increased ten to twenty fold. This rate of maximum fixation approaches photosynthesis maximum rates. The majority of the radioactive products formed under these conditions have been identified and isolated and the distributi… more

Production test 105-2-P (Supplement A) - Activity of pile discharge water (Activation of manganese and iron)

Description: This report discusses the Production Test 105-2-P (Supplement A) -- Activity of Pile Discharge Water. Previous studies of pile discharge water have shown that one of two processes is responsible for the large but variable amount of Mn{sup 56} activity present in the water. One process is the production of Mn{sup 56} by the reaction Mn{sup 55} on manganese impurity in the water. The amount of such impurity has been shown to be too small to produce the observed amount of Mn{sup 56} unless the mea… more

Consolidation and shaping of boron ; summary of previous work

Description: From abstract: "The deposit on the rods is in the form of a brittle uneven tube which is cracked off and subsequently pulverized to a 200-mesh powder. This report is chiefly concerned with methods of consolidating this powder and shaping it into forms required, though it also discusses to some extent other methods of shaping boron or born-rich materials."

Methyl Methacrylate Casting Resin

Description: Abstract: "This report describes work done to improve the casting characteristics of methyl methacrylete resin under CMR-6-18 authorization. The experimental program was initiated with the objectives of decreasing casting time, bubble formation and shrinkage. It has been found that by use of a common solvent for monomer and polymer concentration in monomer can be attained greater than any previously reported in preparation of a methacrylate casting resign. Incorporation of this greater amount o… more

Hanford Engineer Works monthly report, July 1944

Description: This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occ… more

Production of Ta{sup 182}

Description: This memorandum discusses briefly and approximately the two extreme programs which could be followed in the production of Ta{sup 182}: the use of present available excess reactivity, and the use of a pile, continuing no U{sup 238}, expressly to produce Ta{sup 182}. Use of lesser amounts of enriched material would achieve lesser production rates. The cost in fissionable material per gram of active isotope would remain approximately the same.

Fission product studies with plant dissolver solutions: IX-Iodine, X-Arsenic. SE-PC No. 61

Description: In continuing studies to characterize and identify fission product activities formed in the piles and appearing in plant dissolver solutions work was done to determine whether or not long-lived isotopes of certain elements were present. Two of the elements in this category were iodine and arsenic. The iodine isotope of particular interest was I{sup 129}. Its tellurium parent has been identified but no daughter activity attributable to iodine has been observed. The arsenic activities of interest… more

The Effect of Age on the Radiosensitivity of Mice

Description: Abstract: Mice of different ages ranging from 1.5 to 12 months have been exposed to gamma rays in an effort to determine the change in radiosensitivity with age. The dose necessary to cause 50% killing was determined for each age group and sex. No change in sensitivity with age was observed with either sex, although the experimental error in the case of the males was quite large. The females were found to be more resistant than the males.
