Perspectives from Inside the Accelerator Cave
Diagnosis and treatment for breast cancer provides a unique opportunity for a health physicist to see life from the patient's perspective. It also provides for interesting discussions between the patient (the health physicist) and various types of physicians (surgeon, oncologist, and radiation oncologist). This presentation will cover the use of radiation during diagnosis, surgery, and treatment of breast cancer. Doses during diagnostic imagining were not measured; doses from the use of 99mTc in preparation for surgery were measured using a Ludlum Model 19 micro-R meter. During a 6-wk course of radiation therapy, Harshaw Model 707 thermoluminescent dosimeters were used to measure anterior and posterior doses from scatter radiation at five different locations (eyes, thyroid, breast, ovaries, knees). The presentation includes the results of measurements of 99mTc as well from radiotherapy using 6 and 15 MeV photon radiation from an accelerator. The measurement results will be discussed through the eyes of an operational health physicist and in relation to current recommendations to change the occupational dose limit to the eye.
