Callous Disregard  (English, Paperback, Hall Rex Elliot)

Eyewitness account of "Hotsy" Hargan, who worked at the Paducah uranium enrichment plant (Ky), frontend of the US weapons complex, for 40 years. He became a whistleblower and management tried to kill him with radiation. The contractors lied to the workers about the presence of dangerous transuranics and most operators died from cancer. Ultimately the Callous Disregard stemmed from the US government.
