Science Villages in Ukraine still suffering Chernobyl fallout after 30 years â" study
Ukrainian villages are still suffering the legacy of Chernobyl more than 30 years on, new research suggests.
Milk in parts of the country has radioactivity levels up to five times over its official safe limit, it found.
Scientists sampled cowsâ milk from private farms and homes in the Rivne region, about 200km (125 miles) from the site of the Chernobyl Nuclear Power Plant explosion in 1986.
They found levels of radioactive caes ium in milk above Ukraineâs safe limit for adults of 100 Becquerel per litre (Bq/L) at six of 14 settlements studied, and above the childrenâs limit of 40 Bq/L at eight sites.
The highest levels found were about 500 Bq/L â" five times over the limit for adults and more than 12 times that for children.
The study was carried out at the University of Exeter and the Ukrainian Institute of Agricultural Radiology.
âMore than 30 years after the Chernobyl disaster, people are still routinely exposed to radioactive caesium when consuming locally produced staple foods, including milk, in Chernobyl-affected areas of Ukraine,â said Dr Iryna Labunska, of the University of Exeter.
âMany people in the area we studied keep cows for milk, and children are the main consumers of that milk.
âThough the level of soil contamination in the studied areas is not extremely high, radioactive caesium continues to accumulate in milk and other foods, such that the r esidents of these villages are chronically exposed to radioactivity that presents health risks to almost every system in the body â" especially among children.â
The researchers say that some simple protective measures could be taken to bring radiation exposure levels below limits at a cost of less than 10 euro (Â£9) per person per year for the 8,300 people living in the six villages with the highest contamination.
Such measures include applying a caesium binder, called Ferrocyn, to cows, mineral fertilisation of potato fields and feeding pigs with uncontaminated fodder.
The cost of this would decrease each year as radiation levels fall â" but if no action is taken, the experts warn that milk contamination will continue to exceed the 100â¯Bq/L adult limit in parts of Ukraine until at least 2040.
âThe Ukrainian Government has taken some of these measures in the past, but that stopped in 2009,â Dr Labunska said.
âGovernment and international monitoring needs to take place, along with help for people affected by this radiation.
âThis situation should also act as a warning and a reminder of just how long the legacy of nuclear accidents can be.
âWithout adequate countermeasures, what may now seem a purely historical event will remain a daily reality for those communities most impacted.â
