Plutonium not found in workers’ lungs

An earlier report in another facility said one of them showed a high level of contamination in the lungs.

The accident took place last week at a research facility of the Japan Atomic Energy Agency in Ibaraki Prefecture, north of Tokyo.

The agency said it measured as much as 22,000 becquerels of plutonium-239 in the lungs of one of the workers after powdered radioactive materials scattered in a room.

The workers were sent to the National Institute of Radiological Sciences.

Officials at the institute told reporters on Monday that they had conducted up to 4 examinations of the lungs of the 5 workers. No plutonium was detected.

They also said they detected another radioactive substance called Americium. But they did not disclose how much of the substance was found or from how many of the workers. They pointed out that Americium can be created after plutonium undergoes nuclear fission.

An institute in Japan treating 5 workers exposed to radioactive substances says it has not detected plutonium in any of their lungs. (NHK)
