Lead detectors spotted outside Notre Dame Cathedral to thwart contamination risk after destructive fire

Paris's Notre Dame Cathedral is seen today (June 14) with recently installed lead detectors around the perimeter of the historical building to thwart the risk of contamination following the destructive fire on April 15.

French officials are warning people near Notre Dame Cathedral that lead contamination is high in the closed-off plazas and streets surrounding it, according to reports.

The medieval structure and its later additions — including the famous spire — contained lead, which fell to the ground during the fire.

Paris police say lead levels from the roof were found to be between 10 and 20 grams per kilogram of ground — between 32 and 65 times the recommended limit by French health authorities of 0.3 grams per kilogram, according to reports.
