Chernobyl: 25 years after the disaster, debate over health effects remains
Twenty-five years ago Tuesday, a catastrophic explosion at the Chernobyl power plant in Ukraine spewed nuclear fuel into the air. Over 20 days, radioactive smoke and other products emanated from the plant, spreading out over parts of Russia, Ukraine and Belarus and extending, in lower concentrations, around the world.
In the immediate aftermath of the disaster, about 30 people -- mostly firefighters -- died from acute radiation poisoning. A few more died of radiation poisoning over the next decade, and in 2008, a United Nations report concluded that 6,000 thyroid cancers in young people were linked to the accident, too. (Exposure to iodine-131, which was released into the atmosphere during the accident, is known to cause thyroid cancer.)
But even after decades of study, experts are still debating the long-term health effects of the disaster. While the U.N. and other investigators have determined that there is no evidence of excess cancers resulting from the accident, others -- for instance, this blogpost from the Union of Concerned Scientists -- suggest that excess cancers and cancer deaths worldwide will number in the tens of thousands, or even higher.
A comment released Monday from the journal The Lancet explains why it's hard to pin down a number: the research is extremely difficult to complete.
Co-authors Kirsten Moysich, Philip McCarthy and Per Hall, who participated in the U.N. study that found no evidence of excess cancers, noted that there are "considerable logistical challenges in doing epidemiological research in the countries of the former Soviet Union." Researchers have little access to good health records. Potential study subjects speak a number of languages, are culturally diverse and are spread out over a large area. Today, many don't remember details of their whereabouts clearly enough to solidly assess their exposure to radiation. What's more, sufficient funding to put together a well-crafted study would be hard to secure, the authors wrote.
There's a silver lining, of sorts: the recent accident at the Fukushima Daiichi nuclear plant, the authors added, "sadly...offer[s] another opportunity to study the cancer consequences of accidents at nuclear power plants." Unlike countries of the former Soviet Union, Japan has studied the epidemiology of radiation for decades and should be able to put together new, scientifically sound investigations relative quickly, they wrote.
In the fall of 2009 and 2010 Jim Krantz traveled to Ukraine, photographing the individuals still living in the shadow of the Chernobyl Nuclear Reactor, and the abandoned villages that surround it. While there he discovered a long-forgotten eulogy to the village penned by a fleeing resident, celebrating the former glory of the village, the author's home, and promising to return one day.
This letter planted the seed for Homage: Remembering Chernobyl, a new transmedia project consisting of a touring photo exhibition, monograph, and short film produced in collaboration with Emmy Award-winning editor Josh Bodnar.
He also produced a promo reel for it. (Sorry it's in Quicktime so cannot embed)

this is really neat. a new sarcophagus is going to be built.
