Maybe the media hasn't covered Fukushima because only one person has died from it (had a heart attack from cleaning operations) compared to the 15 thousand who died from the tsunami and earthquake. Our media barely covered the pollution threat from the 9/11 attacks (http://en.wikipedia.org/wiki/United_States_Environmental_Protection_Agency_September_11_attacks_pollution_controversy) was that due to fear our country would put a moratorium on future skyscrapers?
All I can say is that Fukushima is definitely the worst nuclear disaster in human history, and worse of all, it's still ongoing with no end in sight. That's the real scary part.
You won't hear of deaths immediately because you need to be exposed to at least 2 or more sieverts for a guaranteed death within a month. But bear in mind that radioactive particles like Iodine, Caesium and Strontium bio-accumulate in the bones and tissue as they tend to substitute Potassium and Calcium in the body, and the radioactive Iodine replaces the Iodine in your Thyroid. The good news though is that, radioactive Iodine poisoning can be prevented by ingesting Potassium Iodine just before exposure to fallout to flood the Thyroid with Iodine. Also the other particles may be expelled months later, or so they say.
However with that in mind even if it a small dose of a few microsieverts, it's safe only if you don't constantly ingest or inhale the contaminated source because otherwise it accumulates in your body over time, subjecting you to a higher daily dose and eventually, health problems as a result. That's also why no-one can compare dosages from radioactive fallout to getting multiple chest X-Rays or Cosmic radiation, as they're vastly different ways and time scales of exposure. It bugs me how the media conveniently forgets to point this out when the nuclear industry tries to bullshit with such arguments of comparison.
TL;DR: You won't hear much because it'll take years to show it's true devastation.
