NOTE: This specification essentially implements the
requirements of NCRP Reports 35, 49 and 102;
however, designers are cautioned to insure that the
requirements of TB MED 521 be met in addition to the
requirements of applicable NCRP publications. In
case of conflict between NCRP publications and TB
MED 521, the more stringent requirements will be
applied.
The installation systems given in this guide

Where details of construction require systems not
included in this guide specification, the guide

specify the required system. Criteria for users on
radiation protection surveys is contained in TB MED
