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.

For each plane over which foil activation was integrated in the preceding article, the corresponding value was calculated by the DAEDALUS code with an assumed set of D-D, hydrogen, and oxygen cross sections. Account was taken of the foil angular sensitivity and the finite size of the source tube. The experimental and theoretical values agree well at individual planes and yield ages of 126 ± 1 cm2 and 129 ± 1 cm2 respectively. Since this slight discrepancy is opposite in direction to that for fission spectrum neutrons, one might suspect that it was caused by unjustifiably ignoring certain effects in the analysis; however, an account of most of these effects would increase the calculated age still further.
