How many alpha particles does a 1 microcurie am 241 radioactive source produce in one second?
Although the radioactive source in a modern detector emits around 37,000 α particles per second, very few of these particles make it out of the detector.
What is the formula for americium-241?
Am
Americium-241 | Am – PubChem.
What is the half-life of americium-241?
Its most stable isotope, americium-243, has a half-life of over 7,500 years, although americium-241, with a half-life of 470 years, was the first isotope to be isolated.
What does americium-241 emit when it decays?
The first decay product of americium-241 is neptunium-237, which also decays and forms other daughter elements. 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.
How many protons does americium-241 have?
95

What kind of radiation does americium-241 emit?
Am-241 is primarily an alpha emitter, but also emits some gamma rays. It poses a more significant risk if ingested (swallowed) or inhaled.
How do you make plutonium 241?
Formation and Grades of Plutonium-239. Plutonium-239 is formed in both civilian and military reactors from uranium-238. The subsequent absorption of a neutron by plutonium-239 results in the formation of plutonium-240. Absorption of another neutron by plutonium-240 yields plutonium-241.
How many neutrons does americium-241 have?

How much of a 1 mg mg sample of americium remains after 3 half lives?
Therefore, there is 0.125 mg of americium remaining after 3 half-lives.
How many protons does americium 240 have?
Americium has an atomic number of 95 (the number of protons in the nucleus of the americium atom).
