radioactive morphine in a doggy bag to go-go or nuked human dust gets in your eye

Here's a fin from a shark of a story from Wired.

In 2007, former Homeland Security nuclear office director Vayl Oxford reported that metal containers like steel and lead could prevent the detection of dangerous radioactive material being smuggled into the country. The same year, an initial test campaign of detectors suggested their effectiveness was shaky at best - though official test results were never released.

I'm just guessing but i bet the US already has the technology to detect nuke matter.
'How much will i bet?' you ask.
The only time i gamble is when i pray.
