  • Atomic structure of irradiated materials is more akin to liquid than glass
    on May 23, 2017 at 4:42 pm

    Materials exposed to neutron radiation tend to experience significant damage. At the nanoscale, these incident neutrons collide with a material's atoms, which then collide with each other. The resulting disordered atomic network resembles those seen in some glassy materials, which has led many in the field to use them in nuclear research. But the similarities between the materials may not be as useful as previously thought. […]

  • In a neutron-rich tin nucleus, electromagnetism can win over the strong force
    on May 19, 2017 at 12:38 pm

    The atomic nucleus offers a unique opportunity to study the competition between three of the four fundamental forces known to exist in nature, the strong nuclear interaction, the electromagnetic interaction and the weak nuclear interaction. Only the much weaker gravitational force is irrelevant for the description of nuclear properties. Although in general the decay of an excited nuclear state follows the hierarchy of these forces, there are sometimes exceptions. […]

    on February 3, 2017 at 4:01 pm

    The benchmark used by the Office for Nuclear Regulation for judging how much should be spent on nuclear safety has no basis in evidence and places insufficient value on human life, suggests a new paper. The review suggests it may need to be 10 times higher -- between £16 million and £22 million per life saved. […]

  • Nuclear CSI: Noninvasive procedure could identify criminal nuclear activity
    on November 1, 2016 at 3:18 pm

    Determining if a person has handled nuclear materials, such as uranium or plutonium, is a challenge national defense agencies face. The standard protocol to detect uranium exposure is through a urine sample; however, urine is able to only identify those who have been recently exposed. Now, scientists have developed procedures that will better identify individuals exposed to uranium within one year. Experts believe this noninvasive procedure could identify individuals who may be smuggling nuclear materials for criminal purposes. […]
