Comments on U.S. nuclear export controls on China
As trade negotiations are in the works between the United States and China, Washington, D.C., has the advantage in semiconductors but nuclear power is a different story, according to a June 9 article in the Hong Kong–based South China Morning Post.

The attenuation of 14.1-Mev neutrons in water has been studied under conditions simulating an isotropic point source of monoenergetic neutrons in an infinite water medium. The migration area of thermal neutrons (⟨r2⟩th/6) was found to be 156 ± 6 cm2. The “age” of indium resonance neutrons was measured to be 150 ± 6 cm2. Fast neutron dose measurements are in agreement with the theoretical calculations of Goldstein et al.
