| EF | 3.1 | 4d9a8790-3ddd-11dd-9b2f-0050c2490048 | cesium-134 | The consensus list is built from this one, so this row is the flow itself rather than something matched to it. |
| ecoinvent | 3.12 | 39b3200d-f95a-413a-9c96-6d90345d9dca | Caesium-134 | A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow. |

Characterisation factors
3- consensus-flow-list 1
- European Commission — JRC 1
- ecoinvent Centre 1
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.
