Normal Tanis particle counts only affected a few species, but high counts could affect almost any species, mostly causing nausea and discomfort.
Species that are affected by normal particle counts were:
- Human: Intensity varies, some will experience only minor effects, others will only be able to withstand a few hours of exposure per year. High particle counts can be fatal in excess of 3 standard hours of exposure.
- Deneri: Extreme nausea even at low particle founts. Unconsciousness at mid-to-high counts. Rarely fatal.
- Madyrn: Exposure is fatal after 1.5 standard hours of exposure.
- D'Auva: After approximately half a standard hour of exposure to even low particle founts, D'Auva will lose feeling in their legs, this will wear off quite rapidly after the ship exits the wormhole.
