List Version Source flow Name there Why this flow
EF 3.1 91d10e9e-1170-4ea9-882a-918e09b9b4a2 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 f6e3282a-7111-49ca-bdc4-854b4b884d92 Technetium-99m The CAS numbers are the same (378784-45-3); both name the same compartment.
ecoinvent 3.8 f6e3282a-7111-49ca-bdc4-854b4b884d92 Technetium-99m The CAS numbers are the same (378784-45-3); both name the same compartment.

Something wrong here?

A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.

You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
