The case study of the inluence to dose rate by major chemical content fluctuation in concrete is implemented based on the investigation of standard chemical contents of shielding concrete that is carring out in parallel. Reffering the results of previously implemented dose rate case study with the chemical contents of existing concrete and assumed contents, the influence to dose rate by major chemical contents in concrete is investigated and summarised.
