Radioseptic
From Star Trek : Freedom's Wiki
A radioseptic is a personal hygiene device used by the Enarans to sterilize their homes and hands, usually before eating. The devices are silver spheres, two or three of which are taken and rolled around in the palms of the hands.
The group known as the Regressives refused to use radioseptics, along with other advanced technology, contributing to the other Enarans' perception that they were a hazard to public health. (VOY: "Remember")
