Automatic measurement of low level contamination on concrete surfaces

Tachibana, Mitsuo; Ito, Hirokuni; Shimada, Taro ; Yanagihara, Satoshi

Automatic measurement of radioactivity is necessary for considering cost effectiveness in final radiological survey of building structures in decommissioning nuclear facilities. The RAPID (radiation measuring pilot device for surface contamination) was developed to be applied to automatic measurement of low level contamination on concrete surfaces. The RAPID has a capability to measure contamination with detection limit of 0.14 Bq/cm$$^{2}$$ for $$^{60}$$Co in 30 seconds of measurement time and its efficiency is evaluated to be 5 m$$^{2}$$/h in a normal measurement option. It was confirmed that low level contamination on concrete surfaces could be surveyed by the RAPID efficiently compared with direct measurement by workers through its actual application.
