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:
“There seems to be no stopping drug frenzy once it takes hold of a nation. What starts with an innocuous HUGS, NOT DRUGS bumper sticker soon leads to wild talk of shooting dealers and making urine tests a condition for employment—anywhere.”
—Barbara Ehrenreich (b. 1941)
“An actor must communicate his author’s given message—comedy, tragedy, serio- comedy; then comes his unique moment, as he is confronted by the looked-for, yet at times unexpected, reaction of the audience. This split second is his; he is in command of his medium; the effect vanishes into thin air; but that moment has a power all its own and, like power in any form, is stimulating and alluring.”
—Eleanor Robson Belmont (1878–1979)
