"They were not blue last week," the team wrote. "We do not know the reason, and we are attempting to catch them so we can find out what is happening."

As things stand, there are roughly 700 dogs roaming wild in the area, most of them being the descendants of the pet dogs that were left behind when the human population was evacuated.

The disaster itself, which happened in 1986, saw the no. 4 reactor of the Chernobyl Nuclear Power Plant explode, contaminating the whole area with deadly radiation.More than 68,000 people had to be evacuated and even today, the incident remains the most serious nuclear disaster in history, costing the equivalent to $700 billion and counting.

Today, the remains of the destroyed reactor are sealed inside a massive containment structure.

Whether the disaster itself is somehow responsible for the dogs turning blue, or if the dogs are coming into contact with some sort of chemical dye or contaminant, currently remains unclear.

Efforts to get to the bottom of the mystery remain underway.
