What is an atomic mass number for the element americium?
Mass number = Number of protons + Number of neutrons For the isotope 241Am the mass number is 241; for 242Am is 242, for 243Am is 243, etc. Americium has isotopes with mass numbers that range from 231 through 249.
What is the nuclear equation of americium?
The nuclear reactions are:Pu-239(2n, gamma)Pu-241(beta)Am-241
Why are alpha and gamma radiations used in americium 241?
Alpha radiation from americium-241 is used in smoke detectors because it ionizes the air particles, causing a small electric current to flow and trigger the alarm. Gamma radiation from americium-241 can be used in radiography to detect flaws in materials or for sterilization purposes.
What is a safety issue with Americium-241?
A safety issue with Americium-241 is its radioactivity, which can pose a risk of radiation exposure if not handled properly. Exposure to Americium-241 can increase the risk of cancer and other health effects if ingested, inhaled, or absorbed through the skin. Proper containment and handling procedures are necessary to mitigate these risks.
What does americium do in smoke detectors?
Americium-241 is used in smoke detectors because it emits alpha particles that ionize the air inside the detector. This ionization process allows a small electric current to flow between two electrodes in the detector. When smoke enters the detector, it disrupts this current, triggering the alarm.
