Photon-beam radiotherapy in pregnant patients: Can the fetal dose be limited to 10Â cGy or less?

This study provides data about the fetal exposure and the contribution of Din to the total fetal dose from conformal radiation therapy. The Din knowledge prior to patient's irradiation enables radiation oncologists and medical physicists to decide whether fetal dose may be limited to 10 cGy or less with or without the introduction of special shielding materials.
