00:00Can you believe that the smoke detectors that every household has are actually radioactive?
00:05The radioactive elements are inside the metal cylinder,
00:08which is also the core component of the smoke detector.
00:11It is called ionization type,
00:13and there are ventilation holes on all four sides so that air and smoke can enter.
00:19Inside it is a short cylinder with a plastic frame,
00:22a metal plate at the top and bottom,
00:24and a small hole in the middle that contains the radioactive substance americium-241,
00:31which will continuously release radioactive particles,
00:34ionizing air molecules to form positively charged ions and negatively charged electrons.
00:40At this time, if a voltage is applied between the two metal sheets,
00:44the positively charged ions and electrons will move to the negative and positive poles respectively
00:50under the action of the electric field, thus forming a weak current.
00:54And then the chip is used to monitor this current.
00:56When there is no smoke, the current remains stable.
00:59And when smoke enters the detector,
01:01the smoke particles will combine with the ions, reducing the number of ions and thus weakening the current,
01:07and the detector will trigger an alarm signal.
01:09But don't worry, the radioactive elements are completely safe in the metal barrel,
01:13but the smoke exposed to the outside will be lost.
01:16So, don't be curious to open it.
