I was just wondering if you could take a small amount of Am241 and use the gamma rays coming off of it to generate electricity. I don't really know how this would work, so that's why I'm asking it here. Thanks in advance!
Sure, you can just absorb the radiation as heat and use it to generate electricity thermoelectrically. This is how the Voyager space probes maintain power, for example. This is also mentioned on the wikipedia page for Am241.
