Procedures for Calibrating Neutron Personnel Dosimeters

Procedures are given for routine testing and calibration of neutron dosimeters and remmeters with radioactive neutron sources. The issues addressed include: the choice of neutron source; phantom construction; fluence to dose eouivalent conversion; and corrections for air scatter, room return, and anisotropic-neutron emission. Explicit, semi-empirical , analytic expressions are given for the room return correction, and calculated numerical values are given for air scatter. Key WDrds: air scatter; calibration; californium; dose equivalent; dosimeter; neutron; rerrmeter; room return.
