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.

The distribution in water of indium resonance neutrons from a 1.4 Mev D-D source has been measured in planes perpendicular to the deuteron beam up to 28 cm in the forward direction from the source. The values of the integrated activities over the planes (including the extrapolated region beyond the range of measurements in each plane) are presented. In addition, a method is described for inferring an age from a D-D source by finding an angle where the distribution is equivalent to that from an isotropic and monoenergetic source. The age of indium resonance neutrons obtained for an equivalent source at 4.3 Mev is 54.4 ± 1.4 cm2. Comparison is made with calculated values of the age.
