I need to perform a variety of dose projections (best guesses) on sheilded and unsheilded odd shaped sources. I would appreciate any feedback on the Microshield and Isoshield codes, including personal experience, contacts for purchasing these codes, and training workshops for these codes. Thanks in advance, Mike Lewandowski mikelew@tis.eh.doe.gov Westinghouse/WIPP (505)234-8419
