Plants Near Chernobyl Adapt To Contaminated Soil 293
lbalbalba writes "In April 1986, a nuclear reactor at the Chernobyl power plant in Ukraine exploded and sent radioactive particles flying through the air, infiltrating the surrounding soil. Despite the colossal disaster, some plants in the area seem to have adapted well, flourishing in the contaminated soil."

Seeds grow fine in both batches, showing that seeds from uncontaminated origin is able to survive the radioactivity in the very first generation.
