The Department of Energy National Nuclear Security Administration Detection of Radiological Threats in Urban Areas
challenge took place in 2019 over the course of two months with a $100,000 prize purse
distributed among the winners.
With 550 registrants, there were 1,614 submissions. The goal of the challenge was to develop an algorithm that can help detect radiation by providing a common data set to evaluate both old and new techniques for detecting nuclear threats. See the Topcoder challenge here.
