Radiometric converter
Radiometric converters were technological components utilized aboard Federation starships in the 24th century, for the purpose of absorbing toxic theta radiation, produced as a byproduct of antimatter waste, and recycling the energy to power various ship systems, such as life support and replicators.

In 2375, B'Elanna Torres, chief engineer of the , described the principles of radiometric converters to Malon Controller Emck, along with those of the transkinetic chamber, as a way of demonstrating the elimination of antimatter waste. Emck, however, received the information less than warmly, as the elimination of toxic reactants would put him out of the waste-exporting business. ()
