Business is booming in the mining zone that supplied uranium for the atomic bombs unleashed on Hiroshima and Nagasaki despite a decree by Congo’s president banning all mining activity here.
President Joseph Kabila ordered the zone closed three months ago amid growing concerns that unregulated nuclear materials could get into the hands of so-called rogue nations or terrorist groups. Yet 1,000 miles away from the capital, Kinshasa, thousands of diggers are still hacking away at a dark cavity of open earth in this southeastern village, filling thousands of burlap sacks a day with black soil rich in cobalt, copper and radioactive uranium.
The illegal mining provides stark evidence of how little control Africa’s third-largest nation has over its own nuclear resources, highlighting the government’s weak authority beyond the capital in the aftermath of Congo’s devastating 1998-2002 war.
“They’re digging as fast as they can dig, and everyone is buying it,” John Skinner, a mining engineer in the nearby town of Likasi, said of the illegal freelance mining at Shinkolobwe. “The problem is that nobody knows where it’s all going. There is no control.”
The raw uranium is an inadvertent addition to the miners’ real prize high-grade cobalt in lucrative concentrations and there is no evidence Congo’s uranium is being spirited away to terrorists. The United States, which pressured Kabila to close the mine out of concern over the uranium, said in March it did not believe there was any “worrisome movement” of the radioactive ore at Shinkolobwe

Ya know, you can blow cobalt up, too…
The cobalt bomb uses cobalt in the shell, and the fusion neutrons convert the cobalt into cobalt-60, a powerful long-term (5 years) emitter of gamma rays. In general this type of weapon is a salted bomb and variable fallout effects can be obtained by using different salting isotopes. Gold has been proposed for short-term fallout (days), tantalum and zinc for fallout of intermediate duration (months), and cobalt for long term contamination (years). The primary purpose of this weapon is to create extremely radioactive fallout making a large region uninhabitable. No cobalt or other salted bomb has been built or tested publicly.
