FIELD: physics.
SUBSTANCE: invention relates to making a grid for selective transmission of electromagnetic radiation, particularly X-ray radiation. The grid comprises a structural element having walls containing a plurality of particles which contain a first radiation-absorbing material. The particles are sintered together to form pores between adjacent particles. Said pores are at least partially filled with a second solid material which contains a radiation-absorbing material. The pores are filled by adding the second material in a liquid, preferably molten state.
EFFECT: improved mechanical stability of the grid and improved radiation absorption properties thereof.
