List Version Source flow Name there Why this flow
EF 3.1 13e353a4-e56c-477b-abd0-4ede4def91ad Technetium-99m The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
ecoinvent 3.12 f09c1931-85fb-4f50-be9d-15d5c0f5e11e Technetium-99m A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent 3.8 f09c1931-85fb-4f50-be9d-15d5c0f5e11e Technetium-99m A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
