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 general expression for the intensity of unscattered gamma rays at points on the axis of a cylindrical absorber, surrounded by a ring-shaped self-absorbing source of rectangular cross section, is derived in terms of two integrals that have been evaluated on the IBM 704 computer. The results are presented in the form of curves from which the intensity can be determined for a wide variety of cases. For points not on the axis of symmetry a solution is given for the special case of source with large peripheral dimensions.
