The 1985 Edition of the IAEA’s Regulations for the Safe Transport of Radioactive Material reinforced the requirement placed on competent authorities to establish compliance assurance programmes that aim at ensuring that the Regulations are met in practice. This book is intended to provide further guidance on developing and implementing compliance assurance programmes to be used by competent authorities. It should also be useful to those competent authorities with established programmes seeking greater harmony in the international implementation of the Regulations. Additionally, it should assist the users of the Regulations in their interactions with competent authorities. (Please note: this publication is superseded by TS-G-1.5)
