You are correct that radiation exposure does statically increase the risk for cancer. A handful of emergency workers did receive exposures above the level where the increased risk could be statistically detected compared to regular cancer risk rates.
So it is possible several people may face an earlier death than they would have if Fukoshima did not occur. But when talking deaths we are still short by 3 to 4 orders of magnitudes to the direct deaths from the earthquake.
