Controlled production of ultrafine metallic aerosols by vaporization of an organic chelate of the metal

Condensation aerosols of actinide and lanthanide compounds are likely to be released when nuclear events involving high temperatures occur. Since reliable physicochemical, aerodynamic or inhalation toxicological data on the condensation aerosols of actinide and lanthanide aerosols are scarce, method...

Description
Summary:Condensation aerosols of actinide and lanthanide compounds are likely to be released when nuclear events involving high temperatures occur. Since reliable physicochemical, aerodynamic or inhalation toxicological data on the condensation aerosols of actinide and lanthanide aerosols are scarce, methods were developed for the generation of these aerosols suitable for detailed laboratory studies and for use in animal inhalation exposures to evaluate their health hazards. The oxides and most other chemical forms of lanthanides and actinides have significant vapor pressures only at very high temperatures at which they are unstable. The diketone 2,2,6,6-tetramethyl 3,5-heptane dione (THD) forms chelates with most metal ions, which are readily vaporized at
