Does radiation make you or your body fluids radioactive? Should I take any precautions at home since I have children?
Michael Corradetti, MD, PhD, Radiation Oncology Resident at Penn Medicine, responds:
Radiation therapy for gynecologic malignancies is typically delivered in two ways.
External beam radiation therapy involves the delivery of high-energy X-rays or particles to a tumor or a tumor bed, from the outside of the body to the inside of the body. Patients often receive daily treatments, Monday through Friday, over the course of 6-8 weeks. Treatments take approximately 20 minutes to deliver, and the radiation passes through the body instantaneously. Patients are not radioactive afterwards.
A second form of radiation therapy -- brachytherapy -- involves the implantation or insertion of radioactive sources into a body cavity or a tumor. The radiation sources, once removed, do not leave radioactivity within the body.
