List Version Source flow Name there Why this flow
EF 3.1 fe0acd60-3ddc-11dd-a7c3-0050c2490048 iodine-129 The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 d5d2c668-24d0-525c-998e-b4f7bf8ae235 Iodine-129 The CAS numbers are the same (15046-84-1); both name the same compartment.
ecoinvent 3.12 106689fa-52d8-4f7d-aa5b-920122aaf1aa Iodine-129 A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent 3.8 106689fa-52d8-4f7d-aa5b-920122aaf1aa Iodine-129 A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.

Characterisation factors

3

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
