(kinetic energy released in matter) specifies the intensity of x-rays at a given point in air at a known distance from the focal spot or source of x-rays, and the cumulative or total (same word) will be monitored during the fluoroscopic procedure

Air kerma

Explanation:

The acronym for the word 'kerma' is . It is the sum or the total of the kinetic energies of the that is liberated by the uncharged ionizing radiation in the small sample of a matter, and is divided by the mass of that sample.

It is sometimes used for expressing the radiation concentration that is delivered to a point.

It is used to specify the intensity of the x-rays for any given point in the air at some known distance form the local spot. The total air kerma can be monitored in the fluoroscopic procedure.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

because if the tool that you are using is not balanced it there would be false mass.
