A better model? Low levels of radiation and health effects
One of the more pivotal issues in facilitating the use of radiation sources—including nuclear power—in the United States (and most of the Western world) is concern about the health effects of low levels of radiation. The current regulatory assumption is that every additional increment of radiation linearly increases the risk of cancer.

Using the NJOY nuclear data processing system, three multigroup MATXS-formatted nuclear data libraries were generated based on the European datafiles JEF-1 and EFF-1, After processing with TRAMIX, TRANSX, or TRANSX-CTR, these libraries can be read into most transport and diffusion codes. For the neutron analysis of gas-cooled or water-moderated thermal reactor systems (including high converter pressurized water reactors), a 70-group WIMS-BOXER structured library was generated. A general-purpose fine-group library in 308 groups is provided for thermal as well as for fast reactor systems. A coupled 175 neutron/42 photon-group library in VITAMIN-J structure was created for the analysis of shielding problems and fusion blanket design. The three MATXS files can be requested from the Nuclear Energy Agency Data Bank.
