Abstract
Objective: Experimental estimate of the secondary radiation on the surface of implants and expanders, used for breast reconstruction in case of mastectomy, after making radiation therapy.
Methods: Special equipment was constructed by radiation study department. It consists of linear accelerator as a source of ionizing radiation and a gamma-ray spectrometer with the detector on the basis of ultrapure germanium. The objects of research were the implants and expanders of the different producers.
Results: The maximum amount of the secondary photons on the implants and expanders was generated on the energy level lower than 700 KEV. The level of photons’ generation between 600–300 KEV was higher on the surface of the implants than on the surface of expander filled with saline.
Conclusion: The photons of the secondary radiation with the energy level from 100 to 700 KEV are generated under the influence of ionizing radiation on the implants and tissue expander filled with saline. It can be one of the causes of capsular contractures development after mastectomy.
