The Japan Power Demonstration Reactor decommissioning program -- Decontamination and radioactivity measurement on building surfaces

In the final step of decommissioning the Japan Power Demonstration Reactor, procedures of decontamination and final survey of radioactivity were studied to release the site from radiation control. Then the procedures were applied to the decontamination and final radioactivity survey. Data and experiences were obtained during these activities. Some parts of controlled area in the JPDR facilities were released.
