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 P0± calculation indicates that neutron detecting foils will cause no flux perturbation when prepared with a moderating ratio equal to that of the medium in which they are to be used. Such foils can be easily prepared from an appropriate solvent and solute. The activity in these foils can be conveniently determined on an absolute basis using liquid scintillation counting techniques, thus yielding an accurate value of absolute neutron flux. Measurements in polyethvlene are reported.
