Is it legal to own americium?
Americium is the only man-made element which is legal to posses, and the amazing part is that you can buy it for less than $10 at any hardware store.
Where can you find americium?
uranium minerals
Americium occurs naturally in uranium minerals, but only in trace amounts. The main source of the element is the neutron bombardment of plutonium in nuclear reactors. A few grams are produced in this way each year. It is also formed when nuclear weapons are detonated.
Is americium still used in smoke detectors?
Smoke detectors are common household items that keep you and your family safe by alerting you to smoke in your home. Ionization smoke detectors use a small amount of radioactive material, americium-241, to detect smoke.
What is AM 241 used for?
Americium-241 is used as a neutron source in non-destructive testing of machinery and equipment, and as a thickness gauge in the glass industry. However, its most common application is as an ionization source in smoke detectors, and most of the several kilograms of americium made each year are used in this way.
Is americium man made?
Americium (chemical symbol Am) is a man-made radioactive metal that is solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors or during nuclear weapons tests. Americium-241 is the most common form of Americium.
What is the symbol for americium?
Am
Americium/Symbol
How common is americium?
Americium is a relatively soft radioactive metal with silvery appearance. Its most common isotopes are 241Am and 243Am. In chemical compounds, americium usually assumes the oxidation state +3, especially in solutions….

Is americium man-made?
How long does the americium last in a smoke detector?
The isotope of americium used in smoke detectors is americium-241, which decays by α emission to neptunium-237 with a half-life of 432.2 years.
How do smoke detectors detect smoke?
Photoelectric alarms work using a photoelectric sensor and a light source. As smoke enters the chamber and crosses the path of the light beam, light is scattered by the smoke particles, aiming it toward the sensor, which in turn triggers the alarm.
How much americium is in a smoke detector?
Ionization-type smoke detector The amount of americium in a typical new smoke detector is 0.29 micrograms (about one-third the weight of a grain of sand) with an activity of 1 microcurie (37 kBq).
What are some of the uses of americium?
Uses of Americium Americium-241 (241Am) is used in very small quantities in household ionization smoke detectors. It plays a part in nuclear power production as a decay product. Due to the scarcity of Plutonium to make spacecraft batteries, Americium can serve as a viable replacement in the forthcoming years.
Where can you find americium-241 in the environment?
Exposure to any significant amount of Am-241 is unlikely under normal circumstances. Small amounts of it are found in the soil, plants and water from nuclear weapons testing. Some smoke detectors contain very small amounts of Am-241.
What is the chemical symbol for the element americium?
Americium is a silvery white solid metal at normal pressure and temperature, its chemical symbol is Am and atomic number 95. Americium metal is highly radioactive, is the fourth synthetic element discovered in the late 1944 from Glenn Seaborg.
Where can you find americium in a smoke detector?
Small amounts of it are found in the soil, plants and water from nuclear weapons testing. Some smoke detectors contain very small amounts of Am-241. There is no health risk from americium in smoke detectors as long as the detector is not tampered with and is used as directed.
