Smoke detectors-reduced and no EMF radiation are a useful item for your home. They keep you informed of any area where a fire might have started that needs your attention. Modern smoke detectors can produce radiation. If you have any issues with being exposed to or sensitive to radiation, you may need to consider the risks.
Looking into the different types of smoke detectors can help to determine the type of radiation they produce. Select a model that will benefit your family with the extra benefit of reduced radiation.
Types of Smoke Detectors
Ionization detectors: This type of smoke detector uses americium-241 or radium-226 in small amounts. Others in this classification use nickel-63. In the ionization chamber, the radiation source sets between two metal plates. As the elements deteriorate, they can give off particles that join other particles called ions.
This method creates a constant current in the ionization chamber. Smoke, if it enters the detector, interrupts the flow and sets off the alarm. This alarm is the best at determining a fire that is spreading quickly with a lot of flames.
Photoelectric Detectors: This type of alarm uses a sensor to identify any light that enters the dark chamber. Any smoke coming into this detector reflects in the sensor, which triggers the alarm to sound. This type of detector easily recognizes any slow smoldering fire with a high amount of smoke.
Combination Detectors: These alarms use both types of chambers-ionization and photoelectric. These work best in areas where there is a possibility of a fast-spreading fire or a smoldering fire.
Smoke detectors and ionizing radiation
The radioactive element inside the chamber of the ionization detector causes the radiation with this type of alarm.
The amount is minimal, with approximately .002 millirems a year. In another measurement, that amount is .00002 millisieverts. A chest x-ray produces .1 millisieverts.
A photoelectric alarm does not produce ionizing radiation. The combination alarms can create a trace amount because of the ionization chamber.
Non-ionizing radiation and smoke detectors
There are several ways a smoke detector can produce non-EMF radiation. When an alarm connects with another WiFi enabled alarm, it can create a low amount of RF-EMF radiation.
A hardwired alarm can produce small amounts of ELF-EMF radiation. Use the EMF meter to determine if there is any level present.
Reducing your exposure
Use photoelectric-only detectors if reducing your exposure is essential.
An excellent option is the First Alert’s BRK 7010B Detector that is hardwired. Check to be sure you are ordering the photoelectric-only smoke detector, the hardwired model with the Photoelectric Sensor.
Schedule battery checks every six months to be sure your detectors are working correctly.
For Your Consideration
Smoke detectors-reduced and no EMF radiation are essential for every home. Photoelectric-only detectors may be the safest option to use if anyone in the household is sensitive to EMF.
