Concentration levels of Radon are measured in Becquerels per cubic metre(Bq/m3).
He called the effect“Becquerel Rays,” assuming that they were similar to X-Rays.
Returning to the field he had created, Becquerel made three more important contributions.
(A Becquerel is a unit of the rate of radioactive decay-
or radiation emitted by a substance.).
In 1896, French scientist Henry Becquerel was working with phosphorescent materials,
which glow after being exposed to light.
Safety guidelines from the Food and
Drug Administration permit foods to bear 1,200 Becquerels per kilogram of radioactive cesium,
but the FDA declined to comment for this article.
Radioactive readings of one of those isotopes, strontium-90, considered dangerous to human health,
were detected at 600,000 Becquerels per liter in some tanks, 20,000 times the legal limit.

As a result of the Fukushima Daiichi nuclear
disaster radioactive cesium concentrations of 110 Becquerels per kilogram were found in silver crucian
carp fish caught in the Tone River in April 2012.
