Static elimination on Bell System teletypewriters

TELETYPEWRITERS which are well known as a means of handling written communications in industrial, government, and police business do not work properly when static is present on the paper. The use of ionizing radiation from radium salt devices to eliminate the effect of static on paper is not new. Such a device is now being used on a nationwide basis by the Bell Telephone Companies during the operation of the page and tape teletypewriters. These teletypewriters may be used in many diverse locations on the customer´s premises, thus raising the question as to potential health hazards to the customer´s attendants, as well as to the telephone company´s maintenance forces.
