PROYECTO de Norma Oficial Mexicana PROY-NOM-042-NUCL-2019, "Categorización de sustancias fisionables y otros materiales radiactivos y requisitos de seguridad física nuclear para su transporte" (Draft Mexican Official Standard PROY-NOM-042-NUCL-2019: "Categorization of fissile and other radioactive material and nuclear security requirements for the transport of such material"). (12 pages, in Spanish)

The notified Mexican Official Standard applies to fissile and other radioactive material that is transported and to the transport units, packages, packagings and packs used when such material is transported by land or by water. It employs a graded approach, in which such material is categorized according to factors such as its half-life, physical and chemical form, degree of dilution, radiation level, quantity, attractiveness, accessibility and use as a weapon. Criteria are established for categorizing fissile and other radioactive material so that nuclear security measures required during the transport of such material can be applied.
