Within the context of energy, frequency, and wave links, explain why magnetic resonance imaging (MRI) which uses radio frequency waves is easier on the body than a computed tomography (CT/CAT) scan

Magnetic Resonance Imaging (MRI) uses radio waves and CT Scan employs X-rays.
X- rays are electromagnetic waves with wavelengths in the range of 0.01 to 10nm and energies in the range of 100 eV to 100 keV and frequency in the range of 3x1019 to 3x1016 Hz.
Radio waves are EM Waves that have wavelength () in the range of 1mm to 100km and the frequency in the range of 300 GHz and 3kHz.
Clearly, the frequency and energy of the X-Rays are more than that of Radio waves. Implying to lesser energy of X rays.
With the lower frequency of radio waves used in MRI, the penetration and effects on the body are much calmer and easier to be handled by the body.
