According to the survey, 1.13 becquerels of caesium-134 per litre of urine were found in an eight-year-old girl – the highest reading for that isotope. The highest reading for caesium-137 – 1.30 becquerels – came from a seven-year-old boy, Kyodo news agency said.

And I\’ll also admit that I get very lost in these various radiation measurements. Rads, rems, becquerels, sieverts, there\’re grays and joules as well aren\’t there?
