How can I get my hair to stay like this?
i would just go to the library if you need to use your computer and i would be nice to your friends and they might let you use their phones
Am-241 emits alpha particles when it decays (radioactive decay). Alpha particles are basically Helium atoms that are missing an electron, so, they are charged particles with a LOT more mass than just a plain electron (about 4500 times more massive). These charged particles are emitted continuously from the tiny piece of AM-241 inside a metal chamber and actually create a very small current that is detected by a sensitive current measuring circuit. Normal air is not ionized by the charged alpha particles, but air containing smoke particles *is* ionized. The particles of smoke give up an electron to the charged alpha particles becoming ionized themselves. This changes the amount of current being detected. When the current reaches a certain threshold level, the alarm goes off. .
