The health effects of acute UF₆ exposure are well documented, with symptoms ranging from respiratory irritation to pulmonary edema. Chronic low-level exposure to uranium compounds has been associated with kidney damage and increased cancer risk, although the risks from environmental exposures near well-regulated facilities are considered low. The NRC and the Environmental Protection Agency (EPA) set stringent air emission standards for uranium enrichment facilities, requiring the use of continuous emission monitoring systems (CEMS) and periodic stack sampling. The NRC's regulatory framework for enrichment facilities includes specific performance criteria for containment and ventilation systems.
