External dosimetry

Experiments on absorbed doses caused by various external x-ray exposure situations were made using Monte Carlo transport computer codes with mathematical representations of an adult human. Especial interest was centered on doses absorbed in the female breasts, caused by some radiological procedures, such as breast therapies, diagnostic radiologies, and pneumothoracic fluoroscopies. Variables studied were breast size, sizes and energies of beams, and the incident locations of beams. Also of interest were doses absorbed by body organs, those not necssarily in the direct beam of x rays
