FUD + nonsense + where is the source?

A quote from the article: The radioactive levels measured were up to 1000 times higher than normal.

First problem: What the heck does ' radioactive levels ' mean? The effective dose-rate of absorbed background radiation? Measured in Sievert/second (or more often in nSv/h)? Or the (simple) dose-rate of the absorbed radiation, measured in Gy/s (or using the base SI units: J/(kg*s)? Or maybe it meant activity concentration of the Cs-137?

2nd problem: Where is the source?

Now it took us only a couple second to find this publication from the IAEA: https://www-pub.iaea.org/MTCD/Publications/PDF/Pub1042_web.pdf which tells as, that the level of Cs-137 (activity-concentration) in the air was increased from the usual 2 μBq/m^3 to 2000 μ/Bq/m^3 (not everywhere, only in some places). Just to see how scary this elevation was, let's compare: The activity concentration of the natural radon-isotopes (daughter element of U-235, U-238, Th-232) are about 10 Bq/m^3 to 60 Bq/m^3 or (10000000 μBq/m^3 to 60000000 μBq/m^3) in the (outdoor)air. Even the atmospheric C-14 is about 40 mBq/s (or 40000 μBq/s).

Well, english is not my favorite language, sorry for grammar/typo... (I forgot to add the other source from the natural occuring isotopes: Radiochimica Acta 70/71, 3 4 5 - 3 5 3 (1995) Title: Radioactivity in the Atmosphere Author: Gäggeler
