Hidden screening devices are used to track the movement of dangerous materials—and recently caught a shipment of uranium at London’s Heathrow Airport.
When radioactive matter is improperly discarded and later discovered like this, the consequences can be chilling . Take the Goiânia accident. In 1987, two men in Brazilfrom an abandoned radiotherapy institute in the city of Goiânia. They suffered radiation sickness almost immediately, experiencing vomiting and diarrhea, among other symptoms, but continued to dismantle the machine, which unbeknownst to them contained the highly radioactive isotope Caesium-137.
There are other similarly bizarre and tragic examples. In Kramatorsk, Ukraine, lost Caesium-137 from a measuring instrument at a quarryand subsequently the wall of an apartment building. Successive residents in the 1980s were exposed to radiation as a result. At least two children died before the source was discovered.
