Abstract：To ensure that the radiation shielding performance of radiation shielding concrete meets the required standards,it is usually necessary to control the elemental content of the concrete under long-term irradiation and high-temperature conditions during the design phase.The study employed various testing methods to measure the content of H and Fe elements in concrete and proposed detection methods suitable for practical engineering projects.The results indicate that for the measurement of the equivalent mass density of Fe elements,the actual results obtained by X-ray fluorescence testing are essentially consistent with those calculated by the direct calculation method,and thus can be applied in engineering projects.For the measurement of the equivalent mass density of H elements,a method that directly tests the water of hydration in concrete and calculates the H element content can more accurately reflect the impact of changes in water consumption and water-to-binder ratio on the hydration water of the paste and the equivalent mass density of hydrogen elements in the system.This method is superior in terms of both testing accuracy and operational convenience,and is recommended for use in engineering projects.
