To prepare to enter the clean room, researchers traverse several transition areas to get increasingly cleaner, dressing in coveralls, hairnets, hoods, boots, boot covers and gloves. “Once we enter the clean room, we do not plan to come out until lunch,” Yu said. “Hopefully, you don't need to go to the bathroom. If you do and have to come out, then you have to change the whole set of protective clothes.” When Yu shows friends a picture of her “bunny suit,” they say, “You must be protecting yourself from radiation.” Yu tells them, “No, no, no, it’s other way around! We are too dirty. Everything has to be extremely clean.”
