Laprascopy-Roentgen

X-rays from about 0.12 to 12 keV (10 to 0.10 nm wavelength) are classified as "soft" X-rays, and from about 12 to 120 keV (0.10 to 0.01 nm wavelength) as "hard" X-rays, due to their penetrating abilities. [ 3 ] Hard X-rays can penetrate solid objects, and their most common use is to take
