Is there any radioactive device inside the smoke detector ?

Some people believe that smoke detectors contain radioactive devices inside and are concerned that they may have adverse effects on human health. In fact, only ionization chamber smoke detectors may contain extremely small amounts of radioactive substances inside.

The ionization chamber inside an ionization chamber smoke detector is usually composed of metal electrodes and radioactive materials. The main function of radioactive materials is to generate gas ions, while the electrodes are used to sense ions in the air, thereby detecting the presence of smoke and dust. However, this type of radioactive material is usually only used in very small amounts, far below the hazardous level, and does not pose a threat to human health.

The photoelectric smoke detector, on the other hand, does not contain any radioactive substances and mainly detects the presence of smoke through two parts: a light source and a photosensitive battery. Therefore, photoelectric smoke detectors are safer because they do not contain any radioactive substances and do not have any adverse effects on human health.

In summary, only a very small amount of ionization chamber type smoke detectors inside the smoke detector will contain a very small amount of radioactive substances, which will not cause any harm to human health. On the other hand, photoelectric smoke detectors do not contain any radioactive substances at all, making them a safer choice.
