What is the OSHA radon exposure limit for adults over a 40-hour workweek?

The Occupational Safety and Health Administration (OSHA) has established guidelines and permissible exposure limits to ensure the safety and health of workers. The radon exposure limit for adults over a 40-hour workweek is set at 100 picocuries per liter (pCi/L). This standard is significant because radon is a known carcinogen, associated with an increased risk of lung cancer upon prolonged exposure.

OSHA’s limit reflects the organization’s commitment to protecting workers from the harmful effects of radon exposure in occupational settings, like mines or buildings that may contain significant radon levels. Adhering to this limit minimizes health risks, allowing workers to operate in environments that might otherwise expose them to harmful levels of radiation. The established limit is a critical benchmark that informs safety practices and the design of radon mitigation strategies in workplaces where exposure could occur.
