INDUSTRIAL HYGIENE GROUP

Exposure Assessment Program


Berkeley Lab is committed to maintaining a safe and healthful workplace. Part of that commitment involves limiting exposures to materials or agents that could be associated with health hazards. The Industrial Hygiene Group maintains the part of this process associated with non-radiological exposures, whereas the Radiation Protection Group handles the management of exposures to radiation related hazards. The process involves measuring, or otherwise establishing worker exposure to, workplace exposures and comparing the exposure to established safe levels.

In addition to chemicals, such as beryllium, asbestos, noise, and lead, which have their own LBNL programs, there are many other substances that have the potential to be harmful if an individual is overexposed. Regulatory limits are established by Department of Energy (DOE) Order 10 CFR 851, which includes the “Permissible Exposure Limits” established by the Occupational Safety and Health Administration.

Also, physical agents, such as noise, non-ionizing radiation (such as radio frequency or microwave radiation), and thermal (heat or cold) stress, can induce injury if a worker is overexposed. Note: laser safety is coordinated through a separate specialized program, see:
