The Fukushima Daiichi nuclear power plant's radiation levels have significantly dropped since the cataclysmic meltdown 14 years ago Tuesday. Workers walk around in many areas wearing only surgical masks and regular clothes.
It's a different story for those who enter the reactor buildings, including the three damaged in the 2011 earthquake and tsunami. They must use maximum protection — full facemasks with filters, multi-layered gloves and socks, shoe covers, hooded hazmat coveralls and a waterproof jacket, and a helmet.
