KCl Crystal Growth and High Energy X Ray Expose of Properties

X ray irradiates material for dose distribution confirmation through material color variation to evaluate about possibility. That is rare earth material to pure KCl and KCl impurity Eu adding 0.5 mol% by Czochralski method each single crystal grow and observed color variation of KCl X ray irradiation use of linear accelerator. High energy X ray irradiation KCl:Eu show the blue fluorescence with purple color that pure KCl single crystal can confirm by show was not observed, but was colored violet. Colors variation of KCl founds stable color center from radiation and this color variation will be used usefully to X ray measurement material and phantom.
