Discuss the basics of radiologic science CORRECT ANSWER X-rays fall between the gamma ray and ultraviolet wavelength range; xrays have between 0.03 to 3 nanometer wavelengths. (associated with short wavelengths) Describe how xrays are produced CORRECT ANSWER Xrays are the result of a high impact of a large volume of heated negatively charged electrons with a hard surface. When this impact occurs, the electrons rupture with the conversion of electrons to x-radiation. Describe the elements o...
