I went looking to see if the commissioned an independant industry standard radiometric spectral survey .. they flew a drone themselves at 100m altitude (standard for big heavy crystal packs - bit high for some lightweight count detector) recording gamma CPS (counts per second total, not banded to identify types of radiation).
They did hire a UK company to compile sat data images (to identify areas of interest)
What's missing from their release is a detailed radiometric techical report - gear that was used, calibrations, raw data, processed "normalised data" etc.

(FWiW I did some decades of radiometric environmental survey work related to geophysical exploration and IAA inspections)
Fair enough, such a team might be biased..
> "Three months later, the Ukrainian government invited Greenpeace to conduct its own radiological survey"
Lmfao, of all the organizations they could have called on, they picked Greenpeace? Anything Greenpeace says about anything nuclear can safety be assumed a lie until proven otherwise. They have negative credibility.
