How many grams of americium are there in a smoke detector?
Most americium is produced from neutron-bombarded uranium or plutonium in nuclear reactors – one ton of spent nuclear fuel contains about 100 grams of americium. It is widely used in commercial ionization chamber smoke detectors, as well as neutron sources and industrial measuring instruments.
How much radioactive material is in the smoke detector?
The smoke detectors in the ionization chamber contain a small amount of americium-241, a radioactive material. The smoke particles disrupt the weak and stable electrical current produced by the radioactive particles and activate the detector alarm. They respond quickly to fires that emit little smoke.
How do you remove americium from a smoke detector?
Americium 241 smoke detectors –
Is it illegal to disassemble a smoke detector?
Well, it is illegal to tamper with smoke detectors in such a way that you are completely alone with them. From what I found on the internet, the americium is bonded to a sheet of metal and then usually pressed into an aluminum mounting disc. It is obviously completely safe and stable, do not eat it or burn it.
Can you touch americium?
During the process of radioactive decay, americium releases alpha particles and gamma rays. Alpha particles are relatively high energy particles, but they only travel extremely short distances and do not penetrate the skin.

Is it legal to own americium?
Americium is the only man-made item it’s legal to possess, and amazingly, you can buy it for less than $10 at any hardware store.
Do smoke detectors still use americium?
The americium isotope used in smoke detectors is americium-241, which decays by α to neptunium-237 with a half-life of 432.2 years.
How dangerous is americium?
Exposure to extremely high levels of americium, as shown in some animal studies, resulted in damage to organs such as the lungs, liver, kidneys, and thyroid gland. However, it is rare for a person to be exposed to amounts of americium large enough to cause harmful effects on these organs.
What if you ate americium?
Americium is extremely dangerous to swallow. This is because it undergoes alpha decay. This means that the helium atom is released from an unstable nucleus. What happens if you eat too much sodium?
Why is my smoke alarm radioactive?
The smoke detectors in the ionization chamber contain a small amount of americium-241, a radioactive material. The smoke particles disrupt the weak and stable electrical current produced by the radioactive particles and activate the detector alarm. They respond quickly to fires that emit little smoke.
Why is americium used in smoke detectors?
Ionizing smoke detectors use americium as a source of alpha particles. Alpha particles from the americium source ionize air molecules. This makes some particles positively charged and others negatively charged. The smoke alarm is activated when smoke interrupts the constant flow of ions.

Why is there a radioactive source in the smoke detector?
Why is there a radioactive source in the smoke detector? makes smoke particles radioactive. ionizes the air. powers the alarm when the battery is depleted.
