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.

An improved pulsing technique is described that should simplify the experimental procedure in obtaining reliable pulsed data for both the α-measurement and the (kß/) technique. It is shown that an equilibrium pulse shape can be obtained by continuing the time-channel analyzer after the last neutron burst to record all of the neutrons arising from the delayed precursors and providing the recording starts simultaneously with the initial burst. The source strength (neutrons per burst) need not be constant.
