Scintillation detectors have been used to detect gamma rays aboard many space missions. They have been used to observe sources of cosmic gamma rays.
Americium has been used in smoke detectors since the 1950s. Its radioactive properties make it ideal for ionizing smoke particles in the detector, allowing it to quickly detect smoke and trigger the alarm.
There is currently a sale on confined space gas detectors at pksafety. They have several models to choose from: http://www.pksafety.com/confined-space-gas-detectors.html
Yes, the metal detectors have been removed from the premises.
For a long time, that was the only means available to them. It's only been comparatively recently that we've had instruments able to detect and measure radio waves from space, or ways to hoist infra-red detectors, ultraviolet detectors, x-ray detectors, and gamma ray detectors up above the atmosphere.
No, NASA did not invent smoke detectors. Smoke detectors were actually invented by George Andrew Darby in 1902. NASA has, however, improved smoke detectors for use in spacecraft and space stations.

The first smoke detectors are based on optical principles - photoelectric detectors.
CO2 detectors are used for detecting levels of carbon monoxide in the air. Many people use CO2 detectors in their homes to prevent carbon monoxide poisoning.
Laser detectors detect laser beams used by law enforcement to measure speed, while radar detectors detect radio waves used by police radar guns. Laser detectors are more precise but have a shorter range compared to radar detectors. It's recommended to have both types of detectors for comprehensive coverage.

The element used in smoke detectors and named after the US is Americium (Am). It is a radioactive element commonly found in household smoke detectors to detect smoke particles in the air.
