There has been a nuclear accident in the French city of Auvignon. Some workers have exposed themselves to radioactive materials and they have been sent to hospital for treatment.
The workers were picking onions from the fields when one man loosed the skin of the onion and juice came out on his arm. The man's friends came to see what was wrong and they got the onion juice on their hands also.
The man who was the first man to get the juice on his arm couldn't say anything so the police don't know what happened. They are investigating from his friends.
The police said that nobody can go into that field for about 40 years. Also nobody can eat those onions. Nuclear accidents with onions are quite common in France.
Onions in France are very strong and people say they are radioactive. If you eat more than one without cooking it will be 'fatal'!
