Abstract: A sanitization device comprises primary emitters configured to emit sanitizing electro-optical (EO) radiation into an interior compartment. A support member is configured to hold and/or secure a target object within the interior compartment of a sanitization device. An end portion of the support member may extend into a secondary compartment comprising a secondary emitter configured to produce external stimulus adapted to excite and recover primary emitters from dormancy. The support member is configured to transmit EO radiation produced by the secondary emitter into the interior compartment to thereby prevent and/or recover from dormancy conditions of the primary emitters. Detection circuitry can detect activation failures of the primary emitters. Thermal management circuitry can limit certain critical failures of a sanitization device that result from activation failures of primary emitters.
