["Dose-risk" relationships at low doses of radiation].

The ionizing radiation is inherently harmful to human beings, and people must be protected from unnecessary or excessive exposure to it. The harmful nature of high doses of x rays has been known for many years. However, for low doses such as those commonly employed in dental radiographic procedures the magnitude of the risk (or even if there is a risk) remains uncertain. The purpose of this paper is to do an analysis of the Dose-risk relationships at low doses of radiation according to the latest recommendations and philosophy of the International Commission on Radiological Protection (ICRP).
