| The hydrogen atom is capable of causing the greatest reduction in energy, so hydrogenous material such as water and wax make the best neutron shields. |
| In the U.S., we import almost everything under the sun, and many of those imports are hydrogenous. |
| Based on new results, the role played by hydrogenous species in the generation is explored. |
| The ratios of hydrogen to fissile material atoms are determined within the fissile region and do not include contiguous hydrogenous materials. |
| For example, elevated temperatures may reduce hydrogen content through loss of bound or free water in hydrogenous shielding materials. |
| These materials are made of a low density solid hydrogenous material which binds a powder of medium density materials. |
