Birds nested using radioactive mud from WW II-era nuclear bomb production plant, stopping attempts to clean up some of the worst leaking atomic waste, much of which is liquid in leaking tanks near the Columbia River. We have nuclear plants leaking radioactive tritium next to the Chattahoochee and Altamaha Rivers, and radiation is detectible in the Savannah River near Plant Vogtle. How many radioactive solar panels or windmills have you heard of?

Work stopped Wednesday morning at parts of the Hanford vitrification plant after radioactive contamination was detected under a bird’s nest, according to Bechtel National.

The contamination is suspected of coming from mud used for the nest, which may have belonged to a swallow, said Bechtel spokesman Todd Nelson. Only a small amount of contaminated soil was found, and the contamination was at a low level.

Should workers believe that?
