>The ex-head of Japan’s Fukushima Daiichi nuclear plant Masao Yoshida, 58, died at a Tokyo hospital of esophageal cancer on July 9, 2013. Doctors have maintained repeatedly that Yoshida’s illness has had nothing to do with exposure to high doses of radiation.

It's fortunate that the article points out that the exposure does not correlate to the incident in the first place, but I get the feeling that the headline given here is link-bait at its worst.
As far as I can tell you, you cannot get cancer six months after being exposed to a high degree of radiation. You either die shortly after a large dose or something appears years if not decades later.
Cancer is a seemingly random, yet likely event.
