The purpose of this Safety Guide is to describe how to apply the Waste Safety
Fundamentals, the Radiation Safety Fundamentals and the BSS in the control of
discharges of radionuclides to the environment from the normal operation of practices
and sources within practices. It provides a regulatory body 
with a structured approach to the limitation of risk to members of the public and
optimization of protection from such operations, which may be adapted to the specific
legal and regulatory infrastructure within which such a body operates. It also gives
guidance on the responsibilities of registrants and licensees in conducting radioactive
discharge operations.
