TLDR
Analysis of data from the ACS/NCI Screening Centers shows current average midbreast doses to be 25 times lower (film/screen) and 3 times lower than the 2 rads previously estimated.Abstract:
Radiation dose from mammographic techniques was determined as a function of surface exposure, beam quality, and depth. Relative exposure vs. depth was measured in tissue-substitute materials by thermoluminescent dosimetry. The f-factors were calculated from elemental compositions of mastectomy specimens. Dose at depth depends on beam quality as well as exposure and tissue composition. Analysis of data from the ACS/NCI Screening Centers shows current average midbreast doses to be 25 times lower (film/screen) and 3 times lower (Xerox) than the 2 rads previously estimated. Quantitative risk indicators other than midbreast dose are also discussed.read more

sources and effects of ionizing radiation
TL;DR: This annex is aimed at providing a sound basis for conclusions regarding the number of significant radiation accidents that have occurred, the corresponding levels of radiation exposures and numbers of deaths and injuries, and the general trends for various practices, in the context of the Committee's overall evaluations of the levels and effects of exposure to ionizing radiation.

The composition of body tissues
H Q Woodard,D. R. White +1 more
TL;DR: A reassessment of the composition data given by ICRP (1975) has been completed, augmented with results from appropriate recent studies, and the compositions presented apply to healthy, adult humans, except for some new material on the bones of children.

Photon mass attenuation and mass energy-absorption coefficients for H, C, N, O, Ar, and seven mixtures from 0. 1 keV to 20 MeV
TL;DR: From this cross-section data base, mass energy-absorption coefficients pen/p, taking into account bremsstrahlung losses and positron annihilation in flight, Compton-scattered and fluorescence photons, and mass-attenuation coefficients p/p are tabulated for the above elements and for the mixtures.

Epoxy resin based tissue substitutes
TL;DR: A series of epoxy resin based tissue substitutes, simulating adipose tissue, bone, breast, lung, muscle and skin, and the versatility of the range of substitutes is discussed in terms of both investigated and projected applications in experimental radiation studies.

Mammography: a contrary view.
TL;DR: There is good evidence that annual history, physical examination, and mammography can reduce short-term and midrange breast cancer mortality by about one third and promotion of mammography as a general public health measure is premature.
