Reporter: Zirconium zirconium industrial zirconium raw material contains a small amount of uranium, thorium natural radionuclide, in order to estimate the dose, with the use of GR-200A-type LiF (Mg, Cu, P) pyroxetil dose monitor external dose of personal exposure. Internal exposure dose mainly associated with inhalation of radioactive dust, for which we measured the production site air
