As the annex to the standard shielding material compositions for shielding calculations, we plan to publish the results of examining the impact on the dose rate after shielding due to differences between the specified concrete composition and the concrete composition used for construction. In this presentation, we will introduce the objectives, summaries, and conclusions of various case studies conducted as part of this impact assessment.
