ANSI/ANS-8.6-1983;R1988;R1995;R2001 (R=Reaffirmed): Safety in Conducting Subcritical Neutron-Multiplication Measurements In Situ

"R" in the numeric designation signifies that the 1995 standard was reaffirmed (recertified) as an American National Standard in 2001.  No changes can be made to a standard during reaffirmation.

This standard provides safety guidance for conducting subcritical neutron-multiplication measurements where physical protection of personnel against the consequences of a criticality accident is not provided. The objectives of in situ measurements are either to confirm an adequate safety margin or to improve an estimate of such a margin.
