To get a closer look at the reactors, we donned anti-contamination gear: safety helmet, dust mask, goggles, two pairs of latex gloves, one pair of cotton gloves, long-sleeved undershirt with breast pockets to hold a dosimeter (a device the size of a flip phone that measures the amount of radiation a person absorbs), disposable pants, two pairs of socks, Tyvek suit, rubber boots, disposable boot covers, and masking tape to seal the shirt cuffs. All of these precautions were supposed to keep radioactive contaminants from getting inside our lungs and on our skin. It provided no protection whatsoever against gamma radiation. A TEPCO handout informed us that our dosimeters were set to beep in 20 µSv intervals. Properly clothed, we clambered aboard a bus upholstered in thick plastic and duct tape.
