Radiation poisoning

Radiation poisoning (or radiation sickness) is a form of organic tissue damage caused by exposure to ionizing radiation. Symptoms vary with the severity of exposure but often include fatigue, nausea, vomiting, and hair loss. Radiation may cause sterility and cancer, and, given a large enough dose, can be lethal. Its effects can be countered for a short time with hyronalin, though adrenaline was once a treatment as well. Extreme cases of theta radiation poisoning can be treated with arithrazine. By the 24th century, cellular damage by radiation could be prevented by taking special inoculations. Radiation poisoning can also lower calcium levels. Exposure to delta radiation also causes severe disfigurement, which could be considered a form of radiation poisining as well. 

In 2063, Lily Sloane was affected by theta radiation poisoning. It came from the Phoenix's throttle assembly, which was damaged by the Borg's attack on Bozeman, Montana. Dr. Beverly Crusher later treated her condition on the USS Enterprise (NCC-1701-E).
