# SUPPLEMENTARY INFORMATION:

## I. Introduction 

The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide 8.1, “Radiation Symbol,” published February 2, 1973. The NRC is withdrawing this regulatory guide because it is no longer required. 

                    Regulatory Guide 8.1 references Title 10 of the                     *Code of Federal Regulations,*                     Subsection 20.203 (10 CFR 20.203), which has been deleted from the CFR. The current regulations for the radiation symbol are found in 10 CFR 20.1901, “Caution Signs.” The guide is no longer required because the current regulations in 10 CFR 20.1901(a) provide a specific description for the design of the approved trefoil radiation symbol. The instructions in 10 CFR 20.1901(a) are sufficient and no additional guidance is needed.                 

Regulatory Guide 8.1 is a one-page guide that endorses American National Standards Institute (ANSI) Standard N2.1-1969, “Radiation Symbol,” dated October 27, 1969. This standard was revised in 1989 and issued as ANSI N2.1-1989. It was later withdrawn in accordance with the ANSI policy not to extend a standard's period of endorsement beyond 10 years and it has not been replaced. 

## II. Further Information 

The withdrawal of Regulatory Guide 8.1 does not, in and of itself, alter any prior or existing licensing commitments based on its use. The guidance provided in this regulatory guide is no longer necessary. Regulatory guides may be withdrawn when their guidance is superseded by congressional action or no longer provides useful information.
