Objective
Given the increase in doses delivered over the years, and in view of the questions raised by certain epidemiological studies concerning an increased risk of radiation-induced cancer in CT scanners, understanding the effects of these low radiation doses has become an important social issue. What’s more, it now appears that individual factors can significantly influence the clinical and biological response to radiation.
Patients and Methods
In order to study differences in recognition and repair of radiation-induced DNA double-strand breaks, we exposed 20 primary cell lines of fibroblasts, astrocytes and mammary epithelial cells to the exact conditions of standard CT scans (brain or thorax) using customized phantoms.
