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 method for determining Doppler broadening which is rigorous for a Maxwellian gas of resonance absorber atoms has been reduced to computation. Doppler broadened absorption cross sections for low-lying resonances of Er167 and Xe135 have been computed both by this more accurate method and by the ψ-function approximation which is in general use. The more accurate method was found to give a correction, compared with the ψ-function method, which was several percent in the case of Xe135 and was less than 1 % for Er167. The time required for the more accurate computation was found to be short enough to be practical for those special applications wehere it is of interest.
