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.

A thin cadmium rod, corresponding to a control rod in a reactor, was placed diagonally in a cylinder containing water. The change in time decay constant of the neutron flux was measured and interpreted as a change in the geometric buckling of the system. The measurements were performed for various ratios of height to radius of the cylinder. The results were compared with calculations where the effective thickness of the rods was estimated in two different ways and the total effect of the rods was obtained by a weighting procedure. The measured values fell between the two calculated curves.
