A combination of the Berger and the linear buildup approximations with the assumption of conservation of energy was fitted for air. The values predicted by this Berger-linear buildup approximation were generally more accurate than those predicted by

Vitrification demonstrations were conducted for surrogates of three inorganic wastewater sludges in a high-temperature, refractory-lined, slurry-fed melter. The total par-ticulate concentrations and melter decontamination factors were determined for

Analytical solutions of the absorbed dose rate integral for a spherically symmetric Gaussian puff were developed for both linear and Berger buildup approximations. Mathematically simpler solutions were also developed for the absorbed dose rate at the

Multi-temporal satellite imagery from the Moderate Resolution Imaging Spectrometer (MODIS) was used to map the different ecosystems of Southeast Asian (SEA) rice paddies. The algorithm was based on temporal profiles of vegetation strength and/or wate

The dominant optical characteristics of Southeast Asia (SEA)'s regional aerosols were determined from the cluster analysis of the 26 AERONET aerosol inversion products, including aerosol light scattering/absorption indicators and aerosol size/shape p

The ANSI/ANS energy absorption buildup factors (ANSI/ANS-6.4.3–1991) were used to determine if they conserve absorbed energy from a point source of monoenergetic photons in an infinite, absorbing medium. Air, water, concrete, iron, lead, and uraniu

Analytical solutions of the dose rate integral for the Gaussian cloud approximation to the Gaussian plume were developed. A solution for the I1 integral for a ground-level source and for the I2 integral for an elevated source were given in terms of s

CAP88-PC, Version 2.0, and NORMTRI, which are based on the Gaussian plume model, were used to estimate the chronic dose due to a continuous, ground-level, atmospheric release of tritium as tritiated water. For the same conditions the predictions of C

Several solutions have been published to predict the rise of buoyant plumes in a shear layer with a power-law velocity profile. Each of these solutions is either a special case or is based on oversimplifying assumptions. In this paper, solutions to t

Tests treating soils contaminated with metal compounds and radionuclide surrogates were conducted in a DC arc melter. The soil melted, and glassy or ceramic waste forms with a separate metal phase were produced. Tests were run in the melter plenum wi
