Analytical search for the stochastic-dominating process in the drift- deposition problem

Description: The random processes in the drift-deposition problem are examined separately to see if any one of them dominates the statistical properties of the outcome. The three prime candidates are assumed to be the drop size distribution, the distribution of break-away points, and turbulent diffusion. It is seen that the drop size distribution probably has dominant infiuence on the deposition of the large-size (drift or carry-over) drops. Turbulence has a comparable iniluence on the deposition of the sma… more

Buoyant plume model for pedestrians

Description: Equations for the steady-state rise of a buoyant plume are derived directiy from the conservation laws for mass, momentam and energy. Top-hat profiles are used and it is assumed that there is no horizontal pressure gradient across the plume's boundary. In the resulting equations there are four unspecified quantities: the drag and heat transfer coefficients, the entrainment velocity and heat production. Results are shown for the (isentropic) case when all these quantities are zero as well as for… more

Confinement of airborne radioactivity. Progress report, January--December 1974

Description: Several commercial activated carbons, marketed for iodine removal in reactor off-gas cleanup systems, were evaluated for iodine penetration at elevated temperatures (4 hr at 180$sup 0$C), and the penetration data varied widely. Subsequent chemical analysis of the samples indicated a strong correlation between the atom ratio of iodine to potassium (I/K) in the carbon and the high-temperature performance data. Iodine penetration tests were also performed on several carbons in an intense gamma rad… more

Contamination limits for real and personal property. Progress report for the period January--June 1973

Description: S>During the initial 6 month period of this project, attention was focused on several individual problem areas, primarily through literature searches ond interpretations of the data found. The first was a review of information on the effects of internal radiation doses to the lung with emphasis on the key question of the possible difference in response between a uniformly distributed dose and the same energy delivered to smaller -masses of tissue from radioactive particles. The second involved … more

Neutron activation techniques for the measurement of trace metals in environmental samples

Description: Neutron activation techniques for measuring trace metals in fresh waters, seawater, marine organisms, sediments, and atmospheric particulates are discussed. Principles of neutron activation analysis, neutron irradiation facilities and procedures, and sample preparation including preconcentration and postirradiation separations are outlined.
