Abstract: Bremsstrahlung means "braking radiation". Radiation is emitted when electrons are decelerated or "braked" when they are fired at a metal target. In this way, we can determine the density of the target material by investigating the electromagnetic spectrum which is emitted from the substance. If, for any reason, a sample density changes the distribution of Bremsstrahlung will also change. By comparing the new situation with the sample condition, we can get information about the target material. Each small change such as temperature change or pressure in conditions affects the density of the target material and the changes in the emission spectrum.
