Abstract

Insoluble radioactive particles have been found in the terrestrial, aquatic and aerial environments. Hot particles are well known as insoluble radioactive particles found after the nuclear tests and the accident at Chernobyl Nuclear Power Plant (CNPP). Hot particles are highly radioactive pieces and mainly composed of nuclear fuel. Insoluble radioactive particles were also found following the Fukushima Daiichi Nuclear Power Plant (FNPP) accident. The particles dissipated from FNPP are almost made of amorphous silica and condensed radioactive cesium (Cs); therefore, they are referred to as radioactive Cs-bearing particles. Radioactive Cs-bearing particles show radioactivity several orders of magnitude lower than hot particles; however, their adverse effects on human health are of great concern. This article summarizes physicochemical properties of radioactive Cs-bearing particles so far reported and discusses their biological effects.
