Radiation levels have decreased since the accident in 2011:

Note that on Safecast, you can enable "Crosshair" in the hamburger menu to see the actual numbers.
The central blob area is currently around 5 μSv/hr, so if you live there for a year it's 44000 μSv, or 44 mSv. The xkcd chart says 100 mSv is the lowest one-year dose clearly linked to increased cancer risk.
So 3 years there equals measurable increased cancer risk.
Cancer risk from radiation is not just the absolute amount of exposure, but the duration of the exposure as well. Short high-intensity radiation doses carry higher risk than long, low-intensity doses.
And 100mSv/yr is a rate, which is greater than 44mSv/yr. After 4 years, you will still have not had the dose needed that is linked with increased cancer risk.
Read it again. Not what they said.
44 x 3 = 132 which is GREATER than 100
You can’t compare exposure over 3 years to a limit for one year.
Radiation damage depends on time period of exposure.
Though I still wouldn't want to live there; the area has been evacuated for good reason.
the graph on the map is μSv/h
using the crosshairs shows 29.88 μSv/h at the waterfront by the plant
that is 0.02988 μSv/h = 261.7488 mSv/a
so not a place I'd want to get food from to say the least
That's on land. Where a whole bunch of various radionuclides have concentrated and remain fixed in place.
This "wastewater release" that's being discussed is the release of low-intensity tritium that will immediately dilute into the whole ocean. You're comparing apples to moonrocks. Completely different things.
Sure, just pick a completely different location to suit the conclusion you already made.
You mean the location right next to where the water has been sitting for how many years now?
