X ray vs ct scan radiation exposure - Answers on HealthTap

Because of the diverging nature of an xray beam, the concentration of xray photons, or exposure, decreases with distance from the focal spot. This is the inversesquare effect. This effect increases the ratio of patienttoreceptor exposure.


X ray vs ct scan radiation exposure - Answers on HealthTap

Xrays make up Xradiation, a form of electromagnetic radiation. Most Xrays have a wavelength ranging from 0. 01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (310 16 Hz to 310 19 Hz) and energies in the range 100 eV to 100 keV. Xray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays.
