Exposure to extremely high levels of americium, as has been reported in some animal studies, has resulted in damage to organs such as the lungs, liver, kidneys, and thyroid. It is rare, however, that a person would be exposed to amounts of americium large enough to cause harmful effects in these organs.
What happens if you inhale americium 241?
Americium and Health Am-241 is primarily an alpha emitter, but also emits some gamma rays. It poses a more significant risk if ingested (swallowed) or inhaled. Americium can stay in the body for decades and continue to expose the surrounding tissues to radiation, increasing the risk of developing cancer.
Is americium in smoke detectors dangerous?
Ionization smoke detectors have a small americium source encased in a layer of foil and ceramic, which stops the alpha particles from traveling outside of the smoke detector. Because of this shielding, the smoke detector poses no radiation health risk when they are properly handled.

Do smoke detectors emit radiation?
Ionization chamber smoke detectors contain a small amount of americium-241, a radioactive material. They react quickly to fires that give off little smoke. Ionization smoke detectors expose people to a tiny amount of radiation—about 1/100 of a millirem per year.
Why is americium named after America?
Americium was the fourth synthetic transuranium element of the actinide series to be discovered. The element was named after America, because it is located below Europium (element 63) in the periodic table, which was named after Europe.
How do you dispose of smoke detectors in California?
If it does not contain radioactive materials per the product description, you can remove the battery and dispose of the alarm/detector in the trash. If your product does contain radioactive materials, the best and safest option is to first check with the product manufacturer to see if they offer a mail-back program.
Do smoke detectors cause cancer?
Smoke detector batteries should be disposed of as explained in What should I do with dead batteries? Health Issues: Radiation can cause cancer and other problems, including defects in unborn children. Radiation produced during normal use of ionization smoke detectors is so low it has no noticeable effect.
What radiation does americium-241 give off?
The decay process continues until stable bismuth is formed. The radiation from the decay of americium-241 and its daughters is in the form of alpha particles, beta particles, and gamma rays. Alpha particles can travel only short distances and generally will not penetrate the outer layer of human skin.
Do smoke detectors still have americium-241?
Fires kill people but smoke detectors don’t even irradiate them. Ionization chamber smoke detectors contain a small amount of americium-241, a radioactive material. Smoke particles disrupt the low, steady electrical current produced by radioactive particles and trigger the detector’s alarm.
How was americium found?
Americium was discovered in 1944 by the American scientists Glenn T. Seaborg, Ralph A. They produced americium by bombarding plutonium-239, an isotope of plutonium, with high energy neutrons. This formed plutonium-240, which was itself bombarded with neutrons.
Why is americium named americium?
How do I dispose of smoke detectors in Los Angeles?
In Los Angeles County, citizens can dispose of their smoke detectors at a Hazardous Household/Electronic Waste Collection Event held throughout the County. For information on upcoming events or for permanent collection centers, please visit the link below or call 1 (888) CLEAN LA.
Is it safe to touch a smoke detector?
Both work very well and are safe to use. There are no health concerns with photoelectric smoke detectors because no radiation is involved. Photoelectric smoke detectors sound an alarm when smoke particles scatter a beam of light in the detection chamber. They respond quickly to fires with lots of smoke.
Why is my smoke alarm radioactive?
Ionisation smoke alarms contain a tiny amount of a radioactive isotope. Therefore, if smoke enters the detecting chamber, some of these ionised air molecules will react with the smoke, causing a change in electrical behaviour – hence triggering the alarm to go off.
