Multiple radiation alarms are being investigated at NASA's Goddard Space Flight Center in Greenbelt, Md.
But radiation was later ruled out as a cause.
A smoke alarm in the radiation lab apparently caused the radiation alarms to sound, according to Prince George's County Fire. The smoke alarm is under investigation. No smoke is visible.
Firefighters stood by while NASA officials and Prince George's County hazmat teams discussed the course of action.
Smoke detectors and alarms are important home safety devices. Ionization chamber and photoelectric smoke detectors are the two most common types available commercially. Because these pages are most concerned with radiation protection, we will focus mainly on the ionization chamber technology. Ionization chamber smoke detectors contain a small amount of radioactive material encapsulated in a metal chamber. They take advantage of the ions created by ionizing radiation to develop a low, but steady electrical current. Smoke particles entering the chamber disrupt the current and trigger the detector's alarm. Ionization chamber detectors react more quickly to fast flaming fires that give off little smoke.

It could very well be just the smoke detector that caused this. According to the EPA: Ionization chamber smoke detectors have small amounts of radiation in them.

Very interesting! If it is radiation you think they would tell the truth? I can see it now, they have their experts airbrushing out all the smoke alarms from any videos taken. Smoke Alarms? What Smoke Alarms!
