"The Terahertz Band covers wavelengths between 0.1 & 1 millimeters. 
Contrary to X-rays, terahertz radiation has a relatively low photon 
energy. Some frequencies of terahertz radiation can penetrate several 
millimeters of tissue with low water content, e.g., fatty tissue. The 
terahertz region is .. generally associated with lasers."

"X-rays have a wavelength in the range of 0.01 to 10 *nanometers* .. "
