摘要：

Radiocesium-bearing microparticles (CsMPs) were released from the Fukushima Daiichi nuclear power plant during the 2011 accident. We examined the CsMP formation process by analyzing Type-A particles and conducting in situ glass fiber experiments. The results demonstrated that heating glass fibers to 450-800 degrees C formed spherical particles, their morphologies and elemental compositions were similar to those of actual CsMPs. The mock-up particles size was strongly dependent on the glass-fiber thickness. Our findings reveal that glass fibers can form microparticles after being exposed to high temperatures.
