Today in Labor History May 20, 1956: In Operation Redwing, the U.S. dropped the first airborne hydrogen bomb over the Bikini Atoll. From May to July, the U.S. detonated 17 nuclear devices in the Bikini and Enewetak atolls. They tested both thermonuclear and fission weapons. They cynically named each of the tests after a different Native American tribe, and then, in the following years, went on to devastate indigenous lands within the U.S. mainland through nuclear mining, testing and waste storage.

Between 1946 and 1958, the U.S. detonated 67 nuclear devices in the Marshall Islands. According to anthropologist Holly Barker, it was the equivalent of 1.6 Hiroshima-sized bombs dropped on the islands every day for 12 years. As a result of these tests, the U.S. completely vaporized three of the Bikini Islands and polluted huge swaths of water and land, poisoning countless indigenous people there. Many starved to death because they were relocated to places that couldn’t produce enough food. Each resident now receives a paltry $550 annually from the U.S. government to cover medical treatment related to radiation poisoning.

Today in Labor History May 18, 1979: An Oklahoma jury ruled in favor of the estate of atomic worker Karen Silkwood. Kerr-McGee Nuclear Company was ordered to pay $505,000 in actual damages and $10 million in punitive damages for negligence leading to Silkwood’s plutonium contamination. On appeal, the court reduced the settlement to a pitiful $5,000, the estimated value of her property losses. In 1984, the Supreme Court restored the original verdict, but Kerr-McGee again threatened to appeal. Ultimately, Silkwood’s family settled out of court for $1.38 million and the company never had to admit any wrongdoing.

Silkwood first started working at Kerr-McGee in 1972. She joined the Oil, Chemical & Atomic Workers union and participated in a strike. After the strike, her comrades elected her to the union’s bargaining committee. She was the first woman to attain that status at Kerr-McGee. In this role, one of her duties was to investigate health and safety issues. Not surprisingly, she discovered numerous violations, including exposure of workers to contamination. The union accused Kerr-McGee of falsifying inspection records, manufacturing faulty fuel rods and other safety violations. After testifying to the Atomic Energy Commission, Silkwood discovered that her own body and home were contaminated with radiation. Her body contained 400 times the legal limit for plutonium contamination and she was expelling contaminated air from her lungs. Her house was so contaminated they had to destroy much of her personal property.

Later, she decided to go public with documentation proving the company’s negligence. She left a meeting with union officials in order to meet a New York Times journalist. She brought a binder and packet of documents supporting her allegations with her. However, she never made it, dying in a suspicious car crash. The documents were never found. Some journalists believe she was rammed from behind by another vehicle. Investigators noted damage to the read of her car that would be consistent with this hypothesis. She had also received death threats shortly before her death. However, no one has yet substantiated the claims of foul play.

`Unlike any other clock, this quantum watch does not utilize a counter and is fully quantum mechanical in its nature. The quantum watch has the potential to become an invaluable tool in pump-probe spectroscopy due to its simplicity, assurance of accuracy, and ability to provide an absolute timestamp, i.e., there is no need to find time zero.`
