Dilithium bomb

A dilithium bomb was a fictional weapon which, in 2370, Kira Nerys, under the alias of Bati Huri, threatened to use on the Cardassian mining moon of Davonia. She claimed the weapons would result in radiation poisoning and hoped the threat would spur the Cardassians on the moon into departing making her mission there a bit easier.
