The radioactive aerosol was produced by irradiation of the inconeltarget with 120-GeV protons in the anti-proton target station at Fermi National Accelerator Laboratory . Consequently, it was found that the particle-size of the radioactive aerosol was proportional to the half-life of the produced radioactivity containedin the radioactive aerosol. The formation mechanism was studied based on the result obtained.

放射性气溶胶是在费米国家加速器实验室的反质子靶站用120GeV质子辐照Inconel靶产生的。结果发现，放射性气溶胶的颗粒大小与所产生的放射性气溶胶所含放射性的半衰期成正比。在此基础上，对其形成机理进行了探讨。
