7 . Ukraine has reported that forest fires have broken out near the site of the world’s worst nuclear accident.
The Chernobyl Nuclear Power Plant (CNPP) is about 100 kilometers away from Kyiv, Ukraine. In 1986, the CNPP had the worst nuclear accident in history. A series (系列) of mistakes and accidents caused an explosion and a huge fire, which burned for nine days. As a result of the disaster, entire cities had to be cleared. Over 100, 000 people had to leave their homes forever. A 2, 600-square-kilometer area around the CNPP was set apart as the “Chernobyl Exclusion Zone” to keep people away from the radioactive pollution.
Much of the land in the Zone is forest and grassland. Radioactivity breaks down slowly over time, so the radiation has dropped some by now. The radioactive pollution has become part of the plants and the dirt in the area. But on April 4, fires broke out in the Zone, which can give off the radioactive pollution back into the air. Once the pollution is in the air, it can be spread by the wind. Over the last 10 days, hundreds of fire fighters have been struggling against the flames. One fire came close to the CNPP. Keeping fires away from the plant is important because dangerous and poisonous material is still stored there.
Fighting the fire was much more challenging than normal because of the radiation dangers. In some places, fire fighters dug ditches (壕沟) to stop the fire from spreading, however, most of their efforts went into pouring water from the air since they couldn’t do the same in most areas.
Ukraine’s government says that there are still some small grass fires, but there are no major open fires still burning. The government says radiation levels in the air in Kyiv and nearby areas are normal.
