Final answer:
Color-coded chips on explosive materials can enhance safety standards and help control and track fissionable materials, supporting international efforts to prevent nuclear proliferation and improve global security.
Step-by-step explanation:
The question of whether more countries should adopt the practice of putting color-coded chips on explosive materials largely pertains to safety standards and nuclear proliferation control. With the availability of fissionable material and the increasing technical expertise to build nuclear bombs by both countries and terrorist groups, the practice of marking explosives for easier detection and tracking seems to be a legitimate safety measure. The use of color-coded chips could enhance the efforts of international agreements and organizations aimed at preventing the spread of nuclear weapons by making it harder for fissionable materials to be used in an unauthorized and untraceable manner. It can serve as a part of control and accountability measures in a world where the presence of such dangerous materials is a challenge for global security.
