Possible danger is nearby

Scientists are warning that it is possible a new disaster could be hiding inforests around the closed power plant.

Canadian scientist Timothy Mousseau is a leading expert on the Chernobyl disaster. He told Radio Free Europe/Radio Liberty that forest fires could sendclouds of toxicradioactive material up into the skies over Europe.

Mousseau said two acts of suspected arson caused ?large fires? aroundChernobyl over the past year. The fires burned a long time, but they ?weren?tparticularly hazardous in terms of radioactivity.?

He added that a third fire last year burned through part of the ?red forest,? which was the most contaminated part of the area. This fire was small, and contained quickly. But, he said, it is the kind that can ?do serious harm if it had spread much more.?

Mousseau explained that the radioactivity in the woods would go back up intothe atmosphere. Depending on which way the wind was blowing, and whether it was raining or not, it could land somewhere else.

His and other research into the Chernobyl accident suggests that the toxic cloud from a major fire could carry different kinds of radioactive materialsacross Europe.

At the time of the accident 30 years ago, he said, a huge cloud from the fire at Chernobyl rose into the atmosphere. This allowed radioactive material, in his words, ?to be transported for thousands of miles.?

Now the risk has increased, partly because of rising temperatures on Earth?s surface. In addition, dead leaves from plants, fallen logs or dry grass couldcatch on fire.

"This dead organic matter on the surface of the soil is highly radioactive,"Mousseau said. When it dries out, it becomes a possible fire threat, and provides the fuel for large and dangerous forest fires.

While it has been 30 years since the Chernobyl nuclear accident, it has beenonly five years since Japan?s deadly Fukushima-1 plant disaster.

Other nuclear disasters

The first big hit to nuclear power came at the end of March 1979. That is when a new reactor in the American state of Pennsylvania partially melted down.

There was no evidence of health issues tied to the accident at the Three Mile Island nuclear power plant. But it started the debate about the safety ofnuclear energy that continues around the world today. People ask whethersplitting atoms to create energy is a safe, effective and economical way to getelectricity to our cities.

There are about 400 reactors working in 31 countries. More than 60 are being built in 15 countries.

The Fukushima disaster will take a century to cleanup and cost hundreds ofbillions of dollars. Nuclear power was not used in Japan for nearly two years, but two reactors were restarted there last year. The debate over nuclear power continues in the island nation. Japan depends on imports for about 90percent of its main energy needs.

Those against nuclear power usually support the use of ?green? power, like wind and solar power. But the supporters of nuclear power say it is safe, and more effective than wind or solar.

Adding to peoples? concerns over nuclear power is the fact that experts still do not agree on how many people lost, or will lose, their lives because of the Chernobyl accident.

Fewer than 100 emergency workers died from the radiation. The World HealthOrganization warned years ago that Chernobyl would cause 4,000 additionaldeaths. But the environmental group Greenpeace ordered a study that shows, in the end, 93,000 people could die.

The town of Chernobyl still is home to about 3,000 people. They continue towork on decommissioning, or closing down, the plant. They are only permitted to stay in the area for 14 days to reduce their risk of radiation exposure.

Scientists say the nuclear exclusion zone will not be safe enough for humans to live there for another 20,000 years.

Yet in one part of the area, a few hundred people who were evacuated havecome back to live. Many of the residents are older adults. Ukrainian officialsquietly let them stay there.

The residents grow their own food, even with the warnings that food could beaffected by the radioactive material. It appears some people who were sentaway after the accident just wanted to be back home.
