Programs and procedures for a large x-ray safety program.

As radiation safety surveys of x-ray equipment are the responsibility of many health physicists, actual procedures vary among facilities. In an effort to share survey methodology of a large research institution, aspects of the x-ray safety program at Los Alamos National Laboratory are described. A definition of an intentional x-ray generating device is proposed in light of the absence or inadequacy of such a definition in applicable federal law and national consensus guidance documents. Regulations and procedures are discussed, and a sample database used in managing the Los Alamos program is presented.

A new 9Be(alpha,n) cross-section evaluation for use in the SOURCES computer code.

Experimental breakup reaction data was the basis for choosing a set of alpha optical potential parameters for calculating the cross section from the 9Be(alpha,alpha'n) reaction with the GNASH code. Although not in complete agreement with experimental values, the promising results suggest additional work and continued research for optimal parameters. Accommodating modifications in the SOURCES code system required improved data and an approximation for the three-body reaction branching fractions is presented as a temporary solution. Experimental spectra from AcBe, CmBe, and simulated AmBe neutron sources are compared to SOURCES calculations using the new branching fractions and serve as benchmarks for this new version of the code.
