High mass in radiographic properties corresponds to density. In radiography, density is defined as the degree of blackening on a radiographic image, which is influenced by the amount of radiation absorbed by the film or detector. High mass refers to materials with a high atomic number or density that can effectively absorb more x-rays.

When an object with high mass is present in the path of the x-ray beam, it will absorb a more significant amount of radiation compared to low mass objects. This absorption results in a darker area on the radiograph where those high mass materials are located, indicating an increase in overall density. Therefore, high mass materials contribute to a darker appearance on the radiographic image, which is a direct reflection of increased density.

Understanding the relationship between high mass and density is crucial for interpreting radiographs, as it helps in distinguishing various types of tissues and structures based on their composition and the way they interact with radiation.
