The Department of Labor, through the Occupational Safety and Health Administration (OSHA), has set a permissible exposure limit (PEL) for lead at 50 micrograms per cubic meter of air over an 8-hour workday. Additionally, an action level of 30 micrograms per cubic meter triggers certain protective measures, such as medical surveillance and exposure monitoring. These standards aim to minimize the risk of lead-related health issues among workers by enforcing safe exposure levels. Compliance with these regulations is essential for protecting worker health and safety in environments where lead exposure may occur.

Permissible Exposure Limit
Permissible exposure limits are levels of exposures permitted by OSHA, the US Occupational Safety and Health Administration.
Permissible exposure limits (PELs) are established by the Occupational Safety and Health Administration (OSHA) in the United States. These limits define the maximum amount of a hazardous substance that workers can be exposed to during a specific time period, typically an 8-hour workday. PELs are designed to protect employee health and safety by minimizing the risk of adverse effects from exposure to harmful substances in the workplace.
The permissible exposure limit (PEL) for lead in the workplace is 50 micrograms per cubic meter of air, averaged over an 8-hour workday. This limit is set by the Occupational Safety and Health Administration (OSHA) to protect workers from the health effects of lead exposure. Employers must take measures to ensure that workers are not exposed to lead levels above the PEL.
Permissible exposure limits are levels of exposures mandated by:
The permissible dose rate in industrial radiography is typically set by regulatory agencies and varies depending on the country and specific circumstances. In general, dose rates are kept as low as reasonably achievable (ALARA) to minimize radiation exposure to workers and the public. Monitoring and compliance with established dose limits are essential to ensure safety in industrial radiography operations.
Molybdenum dusts and fumes can be toxic. The route of entry it through the mouth or nose. Low levels of prolonged exposure may irritate the eyes and skin. OSHA has established a maximum permissible molybdenum exposure in an 8-hour day of 5 mg/m3. Long term exposure to 60 to 600 mg/m3 can cause fatigue, headaches and joint pains.
