The behavior of radioaerosols formed by condensation of supersaturated 137Cs131I and/or 137CsOH vapor in an electrostatic field was studied. Supersaturated 137Cs131I and/or 137CsOH vapor was generated by evaporation of salt crystals from a metal surface heated to high temperatures owing to ohmic resistance. By applying additional potential to the aerosol generator, it is possible to control the behavior of 137Cs131I, 137CsOH, or 137Cs131I + 137CsOH aerosols in an electrostatic field. 相似文献

Sorption of the 131I-, 131IO3
-, and F- ions on various samples of hydroxyapatite (HAP) from aqueous solutions was studied. The HAP samples were prepared by the following reactions: Ca(OH)2 + H3PO4 HAP, CACl2 + Na3PO4 + NaOH HAP, and Ca(NO3)2 + HAP seed + (NH4)2HPO4 + NH3 HAP. None of the HAP samples sorb ionic species of radioactive iodine from aqueous solutions. As for F-, the best sorption properties are exhibited by the HAP sample prepared by the second reaction. The degree of recovery of fluoride ion with the HAP precipitate in 5 min, 4 h, and 5 days of the contact of the solid and liquid phases is 54, 66, and >95% of the initial F- amount, respectively. The distribution factor K
d of the fluoride ion between the HAP solid phase and solution decreases with increasing V/m ratio and pH of the initial solution. 相似文献

The mechanisms of radar reflections from the explosion area and gas wake of operating engines are analyzed; it is shown that the reflections caused by radiowave backscattering from a turbulent gas-like explosion and combustion products can be observed for rather a long time. The results of the investigations into local spatial-temporal characteristics of the disturbed area and radar observations, carried out at wavelengths 10, 3, 0.8, and 0.4 cm are presented 相似文献
