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 comparative method has been developed for the determination of surface areas of UO2 powder. The method depends on the sorption of phosphate ions from a solution containing P-32 labeled NaH2PO4 on the powder surface. By comparison with samples of known surface area, measurements have been obtained in the range 1.0–14 meter2/gm. The internal consistency of the method is better than ±2% and agreement with measurements by the BET method averages around ±5%. The method is simple and fairly rapid, and can be adapted to irradiated material.
