Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium then re-rolling on sheet and foil rolling mills to the desired thickness or by continuously casting and cold rolling.To maintain a constant thickness in aluminium foil production beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high then the rollers
