It is known that a laser plasma produced by focusing a high-power light pulse on the surface of a solid emits x rays. Depending on the intensity of the laser radiation on the target and on the type of target, both the total intensity of the x rays and their spectral distribution vary. An investigation was made of the energy yield of soft x rays at moderate laser-radiation flux densities, 10/sup 11/ to 10/sup 12/ W/cm/sup 2/, which are reached when relatively small commercial neodymium--glass lasers are used. The possibility of radiography of various medical and biological objects in soft x radiation was considered. A neodymium--glass laser operating in the ''giant pulse'' regime with an energy 5 J in the pulse was used.
