Some of the superannuated equipment were replaced in the nuclear fuel reprocessing plant at the Tokai-works of the Power Reactor and Nuclear Fuel Development Corporation (PNC). The authors have been investigating the airborne particle sizes of radiological materials in the decommissioning process using Andersen samplers. This paper describes information on the particle sizes during the cutting processes. The activity median aerodynamic diameters (AMAD) of the aerosols ranged from 2 to 4μm, and their geometric standard deviations were in the range of approximately 2-3.
