Revised neutron/gamma dose estimates in a water phantom for 14. 8-MeV neutrons
Technical Report
·
OSTI ID:5093100
Measurements have been made in a water phantom at the Gas Target Neutron Source utilizing three ionization chambers and a miniature GM counter. Results of cross-beam traverses at 3- and 15cm depths and an axial scan from 3 to 20 cm depth are reported. The two- and three-dosimeter methods reported previously were applied at each measured point to calculate neutron and gamma tissue absorbed doses. Comparison with Monte Carlo calculations indicates that the narrow-beam approximation is not valid for this experimental geometry.
