The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Effects of Chernobyl radiation over many generations

CHERNOBYL RADIATION EFFECTS: 28 YEARS LATER Green Fudge, Irini Chassiotou May 11th, 2014  “……… Many studies have shown that birds living in the area have eye cataracts or smaller brains, while insects, microbes and other decomposers exhibit abnormal behavior. Changes in abundance, distribution, life history and mutation rates are some more documented negative effects of Chernobyl’s radiation on the region’s plants and animals. In fact, the genetic effects of chronic radiation exposure on each species studied so far have often been subtle and varied and only conclusively shown after many generations.

What’s sure is that different species react to chronic exposure in different ways. Research into low-level radiation since 1986 have demonstrated that, for example, pine trees are more adversely effected by radiation than birch, while migrant barn swallows are more radio-sensitive than resident birds. In another study, winter wheat seeds were taken from the Exclusion Zone a few days after the disaster and they were germinated in uncontaminated soil, producing thousands of different mutant strains.  This resulted to genetically unstable new generations, even 25 years after the accident.

Flora and fauna studies may reveal the effects of long-term radiation exposure on humans, obtaining statistically significant epidemiological data on cancer, which is rather complicated. Meanwhile, the Ukrainian government, satisfied with the anecdotal evidence of the zone-based research team, has opened the zone to tourism. Scientists fear that future plans will include repopulating the Exclusion Zone at the earliest opportunity.
