A man outside of Toronto, Canada measures the radioactivity in his garden after a big rain storm on August 14, 2011.

He finds high concentrations of radiation at 20,000 cycles per second, which he demonstrates is likely due to alpha- and beta-emitting fallout particles. This radiation level is over 400 times above normal background radiation levels.
