Radiation Exposure During Pregnancy

There are additional health and safety considerations for employees who are pregnant or planning a pregnancy to minimize exposure of their unborn child.

While an employee is not required to stop working with radiation during pregnancy, there are radiation dose limits that must be observed to ensure the safety of the fetus.

EH&S offers services to pregnant UW employees to help them manage the risks of radiation exposure while pregnant and to keep radiation doses as low as reasonably achievable (ALARA).


The trouble with UV light in your biosafety cabinet

Does your biological safety cabinet (BSC) have an ultraviolet (UV) lamp in it? If so, it may not be as effective for sterilization/decontamination purposes as you need it to be.

Ultraviolet radiation is a form of non-ionizing radiation, and biological effects from it vary with wavelength, photon energy, and duration of exposure. The 100-280 nm wavelength band is designated as UV-C, which is used for germicidal purposes.

The sterilization/decontamination activity of UV lights is limited by a number of factors, including:
