Geiger counter and Am-241

Alpha emission from Am 241 is approximately three times that of radium. I have 0,2 microgramms of Am-241. You can hear the geiger counter on alpha-beta-gamma ray mode.

The counter is 46 years old. A few pictures:

fake

What is fake?

I think that this is not a Am241 source, as polonium9 says,  alpha particles from an Am241 source reach not more than 3cm !

And at the end of the video you can see, that the source looks like a small glass bead.

This is a sign for a Radium-226 source, check wikipedia !

If I am right the Smoke Detector was an old RFT Smoke Detector, Type 70121 .

This is Am241 from a smoke detector. The detector's table says this, not i.

Nice video, i have about two discs of Am-241 from Smoke detectors. I am an element collector so i got almost everything , well not everything but almost.

Well, you can find many types of isotops at unitednuclear, but the site ships only to US :(

[darappah]

finally someone demonstrates alpha emissions from americium :)

[ema576]

its not a fucking microgram is a microcurie

[mbthepixelkiller]

thumbs up fpr GU81

[vmelkon]

@ema576 How much does the americium weight?

[barbalote2]

nice counter!

@omegalab her Brain is a fake :D

@onthecuttingedge2005 It doesnt work. I tried it, but you cant do this with alphas.

[dwarfer777]

maybe this video IS the origin of that mp3

[onthecuttingedge2005]

could you take a piece of glow in the dark material and place it over the 241Americium to see if it excites the Phosphor and causes it to self illuminate, I want to see if alpha is better than beta to self illuminate a glow in the dark object or phosphorescent compound
