List	Version	Source flow	Name there	Why this flow
EF	3.1	adb7954b-da29-4cbb-94eb-32aa7c1ea5af	Krypton-85m	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
ecoinvent	3.12	421a7f1b-01a5-4160-bb7e-32fa8967d9b9	Krypton-85m	A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent	3.8	421a7f1b-01a5-4160-bb7e-32fa8967d9b9	Krypton-85m	A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
