Acute Gamma Irradiation of Quercus Seed--Its Effect on Germination and Seedling Growth

Description: Dormant seed of Quercus alba and Quercus rubra were irradiated with gamma rays from Co/sup 60/ to determine the efiect on cytological and morphological expression in the resulting seedlings. Investigations included varying moisture content and physiological state of the seed prior to treatment, and preliminary evaluation of induced mutation. The following observations were made. The lethal radiation exposure was the same for both species although there were differences in germination within the treatment range of 1 to 10kr. Quercus alba showed an LD/sub 50/ of 6kr with a significant regression for radiation level. The regression of germination on radiation level was not significant for seed of Quercus rubra, but germination was suppressed at the higher levels. These species differences are thought to be due more to physiological than genetic factors. Height growth in the two species was complexed by sprouting in reaction to radiation damage of the apical primordia. Seedling height at the end of one year was not a significant measure of radiation damage. The type of sprouting obtained is discussed in relation to diplotonic selection within the irradiated embryonic primordia. Growth of the root at 10 days following inception was established as a macro-measure of genetic damage. Changes in moisture content (above 25%) or metabolic activity prior to germination did not significantly change the response of root growth to radiation exposure. It is suggested that initial root growth is useful as a bioassay of radiation effect on the seed of woody angiosperms where sprouting is comraon. The range of 1 to 10kr is recommended for use in oak seed irradiation experiments for the induction of mutations. Preliminary evidence at the end of the first growing season indicates that most aberrations observed are generally deleterious to total growth. However, many of the irradiated seedlings were as large as the …

The AECProgram of Atmospheric Radioactivity and Fallout Research

Description: From Health Physics Society 8th Annual Meeting, New York, June 1963. The Atomic Energy Commission's research program on atmospheric radioactivity and fallout is reviewed. The main purpose of the research program is to provide an increasingly complete and sound scientific basis for the prediction of radiation doses to man that may result from the introduction of radioactive material into the atmosphere. Techniques and computation models for making such predictions are discussed. Emphasis is placed on studies of world-wide transport and distribution phenomena associated with fallout from weapons tests and low- altitude local problems arising from industrial and laboratory operations. The program is conducted through research contracts with universities, industrial organizations, and interagency agreements with other government agencies and AEC facilities. A list is appended of current participants in the program. (C.H.)

THE AVERAGE ENERGY AND ANGULAR MOMENTUM REMOVED FROM Dy COMPOUND NUCLEI BY NEUTRONS AND PHOTONS

Description: Excitation functions are presented for many heavy-ioninduced (HI) reactions that produce Dy/sup 149/, Dy/sup 150/, and Dy/sup 151/. Projectiles were C/sup 12/, N/sup 14/, N/sup 16/, O/sup 16, O/sup 18/, F/sup 1 9/, and Ne/sup 20/ of 4 to 10.4 Mev per amu. The reactions studied are all of the type (HI,xn), where x ranges from 3 to 9. A large fraction of the total reaction cross section is accounted for by these (HI,xn) reactions --9/10 at approximately 45 Mev to 1/2 at approximately 105 Mev. An analysis to obtain the energy of the first neutron is presented. Comparison of the results of this analysis to angular-distribution studies suggests that each neutron removes 2 to 4 h units of angular momentum. The relation between the average total photon energy and the average angular momentum removed by photons is obtained. Comparison with the average photon energy from other work leads to an average of 1.8 plus or minus 0.6 h for the angular momentum removed by each photon. The excitation energy E/sub j/ of the lowest-lying state of spin J was estimated. (auth)

THE AXISYMMETRIC FREE-CONVECTION HEAT TRANSFER ALONG A VERTICAL THIN CYLINDER WITH CONSTANT SURFACE TEMPERATURE

Description: Laminar free-convection flow produced by a heated, vertical, circular cylinder for which the temperature at the outer surface of the cylinder is assumed to be uniform is analyzed. The solution of the boundary-layer equations was obtained by the perturbation method of Sparrow and Gregg, which is valid only for small values of the axial distance parameter xi ; and the integral method of Hama et al., for large values of the parameter xi . Heat-transfer results were calculated for Prandtl numbers (Pr) of 100, the Nusselt numbers (Nu) for the cylinder were higher than those for the flat plate, and this difference increased as Pr decreased. It was also found that the perturbation method of solution of the free-convection boundary-layer equations becomes useless for small values of Pr because of the slow convergence of the series. The results obtained by the integral method were in good agreement with those calculated by the perturbation method for Pr approximately 1 and 0.1 < xi < 1 only; they deviated considerably for smaller values of xi .

The Bannock Thrust Zone Southeastern Idaho

Description: Abstract: The Bannock overthrust in southeastern Idaho and northcentral Utah was originally described by Richards and Mansfield (1912) as a single large thrust fault that formed at the close of the Laramide orogeny and was folded by renewed compression near the end of Pliocene time. Later Mansfield expanded and revised his interpretation of the Bannock overthrust so that at least the northern part of the overthrust was thought to be a thrust zone in which the individual faults originated in a folded sole thrust. Detailed mapping in areas critical to Richards and Mansfield's interpretations has shown that the faults thought by them to be parts of one large thrust are separate faults, and that, although some of the thrust surfaces are curved, they were not folded in Pliocene time but probably were folded during a late stage of the thrusting. Extensions of the Bannock thrust to the north, south, east, and west based upon extrapolation of a single large folded thrust surface are not warranted. The Bannock overthrust is reinterpreted as a westward-dipping imbricate thrust zone possibly several tens of miles wide extending at least from southwestern Montana to north-central Utah. It is recommended that the name "Bannock overthrust" no longer be used, and that this zone of imbricate thrusts in the southeast corner of Idaho be called the Bannock thrust zone. The thrusts range in age from Late Jurassic to post- Early Cretaceous and are progressively younger from west to east; strong regional compressive forces do not appear to have been active in the area as late as Pliocene time. The upper plates of the thrusts moved to the northeast in response to an unknown force. Steep eastward-trending tear faults formed during thrusting probably in response to differential movement among the eastward-moving thrust plates. In Tertiary and Quaternary time …

Bucklings, Disadvantage Factors, and [Delta]28 Measurements in Some Undermoderated Slightly Enriched Cores

Description: The reactivity lifetime of a water-moderated, thermal, power reactor using a low enrichment fuel is, in part, dependent upon the conversion ratio. The High Conversion Critical Experiment (Hi-C) was initiated at Argonne to extend the rage of investigations with light water moderated, slightly enriched, oxide-fueled cores. Bucklings were obtained from the clean critical core size and reflector savings values. The so-called "integral" technique was used to measure the disadvantage factor.

The Cellular Differences Between Acute and Chronic Neutron and Gamma Ray Irradiation in Mice

Description: Data from many laboratories are summarized that indicate that for mice the RBE of large single doses of gamma rays or neutrons is about the same for shortening of the life span as it is for acute lethality. However, for chronic irradiation the RBE is quite high for shortening of the life span, due to the fact that very small doses of neutrons are proportionately just as effective as large doses, while for gamma rays, small doses are proportionately only about 1/ 4 as effective as large doses. The reason for this difference was investigated by scoring the chromosome abberations in regenerating liver cells in mice subjected to both chronic and acute neutron and gamma irradiations. The results show that for gamma rays, very small doses are proportionately only about 25% as effective in producing chromosome aberrations as are large doses. However, for neutrons, large and small doses are proportionately equally effective. This result adequately explains the differences in RBE for life shortening and at the same time gives strong support for the somatic mutation theory of aging. Results indicate that for relatively large doses, equal rad doses of neutrons produce about twice the chromosome damage as do gamma rays. This would indicate that the RBE for acute effects can also be explained on the basis of chromosome damage. Following single doses of gamma rays, the percentages of abnormal chromosomes falls slowly over a period of many months, but following a single dose of neutrons the aberration frequency may be as high as 90% and stay this high for at least a year. There is no ready explanation for this difference in reaction to these two radiations. (auth)

Ceramic Materials for Nuclear Thermionic Converters

Description: The developement and fabrication of ceramic-to-metal seals for thermionic converters which will operate in the temperature range of 700 to 1200 deg C are reported. Two ceramic-to-metal seal combinations were developed which show promise for specialized applications. For operation in an oxidizing atmosphere near 700 deg C, magnesia and nickel appear to be a good combination. Seals operating near 1200 deg C, if an oxidizing atmosphere is not present, may be composed of niobium and alumina with palladium serving as the brazing filler. The tungsten metallizing of alumina which contains yttria is a process which appears to have considerable merit. A reaction between the tungsten and yttria is thought to result in an improved ceramic-metal bond. (N.W.R.)
