What’s in your Dubai chocolate? Nuclear scientists test pistachios for toxins
For the uninitiated, Dubai chocolate is a candy bar filled with pistachio and tahini cream and crispy pastry recently popularized by social media influencers. While it’s easy to dismiss as a viral craze now past its peak, the nutty green confection has spiked global pistachio demand, and growers and processors are ramping up production. That means more pistachios need to be tested for aflatoxins—a byproduct of a common crop mold.

An improved thermal homogenization procedure has been developed for fuel regions containing a finite number of thin slab subcells. This procedure applies a “non-cell” correction factor to the usual subcell flux-volume weighted constants, resulting in improved leakages to or from exterior environments adjacent to the homogenized fuel region. The form of the non-cell factor is dictated by a neutron free-flight argument.
