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 use of hot-spot, hot-channel factors to relate system uncertainties and potential system temperatures in reactor design is fairly standard. In this paper a somewhat different approach is discussed. Translating factors are identified for each base variable in the calculation and through statistical regression analysis and error synthesis, procedures are outlined for approximating to the hot-spot temperature and estimating the associated uncertainty in the calculation. The procedures are applied to a typical ETR calculation.
