Stopping Power (particle Radiation)
In passing through matter, fast charged particles ionize the atoms or molecules which they encounter. Thus, the fast particles gradually lose energy in many small steps. Stopping power is defined as the average energy loss of the particle per unit path length, measured for example in MeV/cm (see figure to the right). Stopping power is a necessary ingredient for many parts of basic science, for medical and for technological applications.

Famous quotes containing the words stopping and/or power:
“Would not some lightning flash of vision sear peoples consciousness into life again? What was the good of stopping the war if armies continued?”
—John Dos Passos (18961970)
“...I am who I am because Im a black female.... When I was health director in Arkansas ... I could talk about teen-age pregnancy, about poverty, ignorance and enslavement and how the white power structure had imposed itonly because I was a black female. I mean, black people would have eaten up a white male who said what I did.”
—Joycelyn Elders (b. 1933)
