Evaluation of Fetal Dose in Breast Radiotherapy With Shielding and Wedges

The fetus may be seriously affected by the peripheral dose when a pregnant woman undergoes breast radiotherapy. To quantify this dose, a humanoid phantom was irradiated at the left breast, simulating breast radiotherapy. The phantom, consisting of an adapted manikin (with internal and external materials having densities close to that of water), was irradiated in a 6-MeV X-ray linear accelerator (C...
