Subject: I took apart a smoke alarm and now im scared about the radiation now

i dont know if this is the rght spot, btu i didnt know how to contact you. I 
stupidly took apart a smoke alarm, broke through the metal cage, and got to 
the little metal disc thingy inside which holds the americum. I realise how 
stupid it was and quickly through it away. How easily could it become 
disladged and inhaled or consumed? I'm terrified i ahve alpha emmiting 
radiation inside me with a 500yr half life!
