To construct sex-specific adult computational phantoms covering 10th, 50th, and 90th percentiles for height and weight to assess how body dimensions influence radiation doses.
Constructed 18 anthropometric standing adult human phantoms (nine male, nine female) using Caucasian ergonomic target metrics extracted from PeopleSize software.
Modeled body mass variation as changes in subcutaneous adipose tissue while keeping organ masses constant, scaled organ sizes with height using autopsy data, and maintained a constant body mass index for each mass percentile.
Calculated organ equivalent doses under external radiation exposure and evaluated specific absorbed fractions across all phantom configurations.
Under external exposure, equivalent dose decreased with increasing body mass for deep organs shielded by subcutaneous fat (such as liver, colon, and stomach), but remained constant or increased for surface tissues (breasts, testes, and skin) due to scatter radiation.
Variations in standing height exerted minimal effect on external organ equivalent doses, whereas specific absorbed fractions decreased with height and increased with body mass.
Body mass alterations produced substantial dose shifts in deep tissues, whereas the impact of height differences and mass changes on superficial organs and internal exposure remained small to moderate.
