Placards must be printed in the square-on-point configuration measuring 250 mm on all sides (about 10 x 10 inches) and include a solid inner border that is 12.5 mm from the edge of the placard. The number â7â at the bottom of the placard is the UN hazard identification number for radioactive materials. It is located at the bottom corner of the placard and must measure at least 41 mm.
