Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can ...

This study aimed to measure scattered dose and estimate organ dose during mammography under conventional...
Accurate absorbed doses of 60 Co γ radiation were delivered to samples of SiO 2 . The work described here can be applied to arbitrary materials with a known elemental composition. The Australian primary standard of absorbed dose is a graphite calorimeter. The absorbed dose to other materials is...
We estimated the minimum, maximum and mean values for glandular tissue dose for populations of exposed women within 5-year periods from 1960 to the present, with the minimum to maximum range likely including 90%% to 95%% of the entirety of the dose range from mammography in North ...
