Koreans wary of radioactive rain

Yesterday we experienced a king of a "big" environmental/human/ecological problem : Radioactive rainfalls all over Korea.

I was first ok with that, we just had to took an umbrella and stay under this umbrella everytime we went outside (the umbrella protected us against the radioactive raindrops). So basically that was ok, we were told not to go outside if we do not have something to do outside. But every worker worked, every shop was open, everything was still working.

The fact is now, this morning I'm thinking about something else : ok, individuals are safe, thanks to their umbrellas, but what about the the ground ? It was raining all day long ! the rain probably seeped into the soil. So now, what about the water pollution, what about the plantations ?

I mean, radish is one of the most common and popular side dish in Korea, and as you probably know, radish directly comes from the ground, so basically, from now, are we gonna have some radioactive radish as a side dish ?

This is kind of a big deal .... because as a french, I could not read well and guarantee the provenance of the products that I consume. Everything is written in Korean (when it's written, because sometimes, nothing indicates where do the product come from) so how to cope with it ? Good question ....
