Neutron Shielding Materials

[stallsmi@gdls.com]

Good Morning RadSafers:



I am interested in reducing a 1E12 neutron fluence (1 Mev spectra) from a

nuclear weapon by a factor of one-fifth to one-tenth.   What are the best

neutron shielding materials that could be used?  Space claim of the shield

is an important consideration in evaluating potential materials.  In

addition, the shielding of the gammas produced by neutron capture may not

be a problem for the application in question.



Any advice or references would be greatly appreciated.



Thanks in advance.
