Nuclear Lab Develops Powerful Dust Rag

(AP) -- This is one cleaning that could pass anybody's white-glove test. A high-tech dust rag developed by a research chemist at a nuclear weapons plant can pick up potentially deadly beryllium particles that are 20 times smaller than what can be seen with the naked eye. Its inventor, Ron Simandl, says it could be used to mop up industrial accidents or wipe down semiconductor "clean rooms."
