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.

The four-factor critical equation for a heterogeneous thermal reactor is looked at in detail. It is then written in terms of parameters which characterize separately the fuel element, the moderator, and the lattice cell geometry of a heterogeneous thermal reactor. Methods for determining the parameters are then discussed. The results of measurements and analysis for two different fuel element types are compared with the results of measurements made on full lattices consisting of these fuel elements.
