This Handbook describes an implementation process for core training as recommended in Implementation Guide G441.12A, Radiation Safety Training, and as outlined in the DOE Radiological Control Standard RCS - DOE-STD-1098-99]. The Handbook is meant to assist those individuals within the Department of Energy, Managing and Operating contractors, and Managing and Integrating contractors identified as having responsibility for implementing core training recommended by the RCS. This training is intended for general employees to assist in meeting their job-specific training requirements of 10 CFR 835. While this Handbook addresses many requirements of 10 CFR 835 Subpart J, it must be supplemented with facility-specific information to achieve full compliance.
