Un ano mas tarde, Antoine Henri Becquerel
y los esposos Curie recibieron el Premio Nobel de Fisica, el primero por su "descubrimiento de la radiactividad natural", y los Curie por su "investigacion de los fenomenos de radiacion descubiertos por Becquerel
determined that the element uranium was the source of the emission rather than any of its compounds.
Sure enough the plate was fogged and Becquerel
decided that fluorescence did produce X rays.
Sadly he had no idea just how dangerous his new discovery was: The first safe exposure limits only came in to force 30 years later and by then it was too late for Becquerel
and his fellow workers.
The Japanese limits for the ingestion of drinking water by infants is 100 becquerel
In 1903, they received the Nobel Prize for Physics with Becquerel
for the discovery of radioactivity.
For their work on radioactivity, the Curies shared the Nobel Prize for physics with Becquerel
(see 1896) in 1903.

The Kyodo news agency quoted the prefecture as saying that it has asked the city of Soma and dealers to stop shipment of the mushrooms, and a local agricultural cooperative has begun recalling them after they were found to contain 850 becquerels
of cesium per kilogram, exceeding the 500-becquerel
limit set by the state.
The projection had been based on an assumption that 1 becquerel
of iodine-131 is discharged from the nuclear plant every 72 hours.
The highest values were observed in the prefecture of Tochigi with 320 becquerel
per square metre for iodine-131 and 73 becquerel
per square metre for caesium-137.
