- •
We measured 127I and 129I in rainwater samples from Fukushima in 2012–14.
- •
129I and 129I/127I followed declining trends since the 2011 accident.
- •
High 129I was attributed to resuspension and re-emission of deposited 129I.
- •
Fukushima-derived 129I contributes less to the atmosphere since 2014.
