Will Boisvert reports that four years ago a large earthquake and tsunami devastated northeast Japan. More than 15,000 people were killed. A subsequent nuclear meltdown added fear to grief. As terrible as the meltdown appeared to be - with the accumulated hydrogen gas igniting and blow the roof off the pumphouse, it did not have significant public health consequences, much less catastrophic than many feared and some continue to claim. On the fourth anniversary of the tsunami, earthquake, and meltdown, journalist Will Boisvert investigated and unearthed five public health findings from Fukushima that you have probably never heard:
1. Thyroid Cancer Rates Lower in Fukushima Children Than Other Regions.
2. Fukushima Seafood Safe to Eat.
3. Fukushima Evacuation Zone Is Mostly Habitable.
4. Cancer Rates in USS Reagan Crew members Lower Than Control Group.
5. No one in Fukushima, neither plant workers nor civilians, suffered immediate harm from the radiation. Long-term effects, mainly cancer, are the chief concern. But radiation is such a weak carcinogen that it is often impossible to tell how much risk it poses. That problem has led to bitter disputes over the linear no-threshold - LNT - theory of radiation and cancer the no safe dose model that predicts that any exposure to radiation, no matter how small, will causes a proportionate increase in cancer risk. Mainstream radiology largely accepts LNT, but some scientists contend that radiation doses below about 100 millisieverts - mSv - pose no cancer risk.
