Ionization Detectors: Ionization Chamber An ionization chamber is very simple. It consists of two plates with a voltage across them, along with a radioactive source of ionizing radiation, like this: The alpha particles generated by the americium have the following property: They ionize the oxygen...

Americium-241, a radioactive element best known for its use in smoke detectors, is a good example of an element that undergoes alpha decay. An americium-241 atom will spontaneously throw off an alpha particle. An alpha particle is made up of two protons and two neutrons bound together, whic...
Smoke detectorsby Chris Woodford. Last updated: March 19, 2023.We've all heard of Native Americans who used smoke signals to send simple messages over long distances. But sometimes when we see smoke it's sending a message that's very alarming: there's a fire nearby and our life is in ...
How does americium-241 work in smoke detectors? How does an ultrasound make shear waves? How can a person detect infrared rays without an instrument? How do particulate matter sensors work? Is an ultrasonic sensor analog or digital? How was the seismograph invented?
How many grams of this isotope in a 4.00 g sample will remain after 112 years? The half-life of Sr-90 is 29.1 years. How many years would it take for a 1.0g sample of Sr-90 to decay to 0.25g? Americium-241 is u...
