Nuclear forensics is effective measure for strengthening nuclear security through the analysis of origin and characteristics of nuclear materials or radio-isotopes collected at the crime scene inspections. In the development of nuclear forensics laboratory/library, "Chain of Custody" should be kept in mind on the view point of juridical process. Each nation should develop own national response plan to stipulate the framework for integrated nuclear forensics activities. Good practices for stipulating national frameworks for nuclear forensics are investigated in advancing nations such as US, EU and Canada. Issues and measures are proposed aiming at improving its framework.
