It’s a colorless, toxic gas. A US woman won $363m after years of exposure

For more than 30 years, Susan Kamuda lived with her family several hundred yards away from an unassuming brick building situated in a small office park.

Kamuda’s son, Brian, remembers riding his bike past the building on his way through the neighborhood; he later taught a girlfriend to drive in the nearby parking lot.

Neither Kamuda nor the surrounding community knew that the building housed a company that was spewing a colorless gas into the skies above Willowbrook, a middle-class, suburban enclave south-west of Chicago. A company called Sterigenics used the gas, ethylene oxide (EtO), to sterilize medical devices and other products.
