In 1971, a clinic in Brazil bought a radiation therapy machine. Fourteen years later, the practice closed and was abandoned. On September 13th, 1987, two men sold the inner canister of the machine for scrap. Upon breaking it open, a scrapyard employee found sparkling, glowing blue powder. It was distributed to family and friends, who used for decorative and magical purposes. Sixteen days later, 112,000 people were in Olympic stadium, being tested for radiation poisoning.
