"No compensation or recognition of cancer-caused deaths has come from the Federal government."

The government cannot do this. It would be an admission of MANY things. I know a widow who receives a pension which is not taxable. It is a "compassionate" pension. The government absolutely denies that radiation from her husband's service in the nuclear industry caused his death... they cannot admit it because many more cases would qualify for compensation, including the general public, farmers who lost animals...
