Radiation (Su)

Source: Starfinder Core Rulebook p.104

Alignment: Photon

As a standard action, you can emit an aura of low-level radiation. Creatures within 5 feet of you must succeed at a Fortitude save or be sickened. A sickened creature recovers as soon as it moves out of your aura, and a creature that succeeds at its saving throw is immune to your radiation for 24 hours. This is a poison effect. The radiation lasts for 1 round or until you leave photon mode.
When you are attuned or fully attuned, the size of your aura increases to 10 feet.
