TaStrIeueroll tiaun DY a2 LaOCLUL OL £4. OLM 2liclwes UL SLeSeL OL ait SLUCS were found necessary to reduce the slow-neutron flux by a factor of 2, and concrete was found to be less effective in cutting down the number of slow neutrons. In general, the fast neutrons travel in the direction away from the point of detonation, but the slow neutrons were found to be non directional.
