hmm well according to the sources I have at hand uranium 238 ( the most common form) has a half life of 4.5 billion years. and the half life of uranium 235-( the kind used in fission reactions and much rarer) has a half life of 713 million years. just thought that should be said and someone else out there please correct me if I am wrong.
Thanks for pointing out my error. I didn't realize how far off my estament was regarding the half-life of Uranium.
I hope you didn't take offence to that. I don't think the battery runs on radioactive decay but perhaps controlled fission? I think that may be somewhere in the Let's talk tech thread. if that were the case maybe you could have enough uranium to last an extended period of time
We think that the nuclear battery runs off a matter/energy exchange, much like happens in the scanners - also I doubt it is uranium that is used - if it were, then Jeremie and Peter Duncan both have critical poisoning - what is most likely is that an isotope of Uranium is used called Lead210 - this has a half-life of 20-30 years as well which is perfect for the show - the emitted radiation is also particulate, meaning there is no gamma-radiation to cause radiation poisoning.
very good work TB3 I just couldn't remember what you said. I appreciate you explaining that because yeah the two would have critical posioning from exposure. Im not at college yet, but I want to major in science. I like the idea of Lead210, for the reasons you stated. this is why you are a lyokologist and I am not
. again kudos.
