TL;DR: The measurements made across Europe following the releases from the Fukushima NPP reactors have provided a significant amount of new data on the ratio of the gaseous ( 131)I fraction to total (131)I, both on a spatial scale and its temporal variation.

TL;DR: The model age of the radioruthenium supports the hypothesis that fuel was reprocessed ≤2 years after discharge, possibly for the production of a high-specific activity 144Ce source for a neutrino experiment in Italy.
Journal ArticleDOI

TL;DR: Inverse modeling simulations indicate that the widespread detections of 131I resulted from the combination of multiple source releases, and among them, those from radiopharmaceutical production units remain the most likely.
Journal ArticleDOI
Plutonium isotopes in the atmosphere of Central Europe: Isotopic composition and time evolution vs. circulation factors
Renata Kierepko,Jerzy W. Mietelski,Zbigniew Ustrnul,Robert Anczkiewicz,H. Wershofen,Zoltan Holgye,Jacek Kapała,K. Isajenko +7 more
TL;DR: Evidence of Pu isotopes in the lower part of the troposphere of Central Europe and results of the model suggest that Pu from nuclear weapon accidents or tests and nuclear burnt-up fuel are present in the air.
Journal ArticleDOI

TL;DR: For about four weeks, the fires spread around and into the Chernobyl exclusion zone (CEZ) and came within a few kilometers of both the CNPP and radioactive waste storage facilities.
