Florida ? More than 70 people underwent decontamination Monday after being exposed to radiation from an exploded krypton gas container at a defense contractor’s plant, officials said.

No one was in danger of being exposed to a life-threatening dose, authorities said.

Sixteen people were taken to a hospital after complaining of nausea, said Bennie Seth, a fire and rescue spokeswoman. No one was seriously ill.

Seventy-three people were exposed to levels of radiation high enough that they had to be decontaminated, Seth said.

Krypton gas is colorless and nontoxic. It can be made artificially radioactive for use in manufacturing. The krypton at the plant was used for making medical supplies, Seth said.
