TRANSNET

TRANSNET is a system of data bases, analysis codes, routing algorithms, and information packages that are available to anyone interested in the transportation of radioactive materials. The system resides on a central computer that can be accessed by authorized users to either gain information or perform analyses of radioactive material transportation systems. An authorized user can access TRANSNET with a modem-equipped personal computer. The system first went on-line in 1987 from a dedicated minicomputer; it is now on a UNIX-based workstation.

RADTRAN, resident on TRANSNET, is a computer code that analyzes the radiological impact of transporting radioactive materials. The first version was developed by Sandia in 1975; since then there have been four updates of the code with the development of a prototype version of RADTRAN 5 in 1995 which includes model improvements and expanded analytical capabilities.
