Abstract
The particle sizes and fuming rates of radioactive nuclides and matrix elements were extensively investigated for aerosols generated by the heat cutting of activated metals. The aerosols showed either lognormal activity or mass distributions with modes at 0.3 similar to 0.5 mu m and/or 4 similar to 6 mu m. Some carrier-free radioactive nuclides wer e remarkably enriched in the aerosols, and showed different distributi on patterns from matrix metal elements. The results are discussed on t he basis of the thermal properties of the radioactive and matrix eleme nts.
