national sacrifice area 

RADIATION SAFETY

A short-lived euphemism proposed by the US Department of Energy for a region that would become a de facto repository for highly radioactive materials, where hundreds of thousands of tons of waste would have been consolidated, stabilised, packaged, re-disposed.

Hanford, the largely de-commissioned nuclear production complex on the Columbia River in Washington State was proposed as a sacrifice region. Most of 63 short tons of plutonium for the 60,000 nuclear weapons once in the US arsenal were produced in Hanford
