The derelict radiotherapy clinic in Goiania from which the cesium device was taken.

In September 1987, a canister of cesium-137 was taken by scavengers from an abandoned medical clinic. The canister was subsequently broken into parts and pried open. The blue radioactive powder was distributed throughout the community of Goiania, Brazil. Wind and rainwater runoff also helped to spread the radioactive contamination.

The incident resulted in four deaths, one amputation, 28 people with radiation burns, and monitoring of more than 112,000 people (most of whom experienced no contamination). The physical decontamination effort covered about one square kilometer (roughly 40 city blocks), demolished seven homes and some other buildings, and produced about 3,500 cubic meters of radioactive waste. Economically, the clean-up costs themselves amounted to $20 million, and up to hundreds of millions of dollars were estimated to have been lost with collapses in tourism and business. Many people left the area due to fears of remaining contamination, and although not contaminated, prices of manufactured products fell by 40 percent and stayed at that level for 30 to 40 days.

This incident provides some sense of the possible physical and economic effects of a radiological attack.
