From Eyewitness News:

ASTORIA, Queens (WABC) -- A hazardous material teams investigated a possible radiation scare at a house in Queens.

A box with a radiation symbol was found inside an apartment on 45th Street in Astoria Tuesday.

Newscopter 7 flew over the building while Hazmat and the bomb squad sorted through boxes.

The owner died, and donated everything to charity.

While his belongings were being packed up, a suspicious box was discovered.

It tested positive for trace amounts of radiation.

It turns out the box was full of rocks that emit low levels of radiation.

Note how the video from WPIX and the ABC story differ quite a bit. Which one is the truth?
