“Natural” as opposed to? :)
- godelski 6y agoPlutonium is not a naturally occurring element. Plenty of stuff is man made.
- chrisseaton 6y agoNatural as in naturally occurring. Coal is formed and burns in nature with no interaction from humans. Plutonium does not occur naturally in detectable quantities. It only does so through human action.
- XorNot 6y agoAsbestos forms naturally too.
- chrisseaton 6y agoNot sure what you’re trying to say? Asbestos is a natural mineral - not sure where you think that fits into this or how it’s relevant, sorry. We aren’t just listing all things that are naturally occurring!
- XorNot 6y agoIt was implied in the parent context that the fact coal is "naturally" radioactive somehow matters to the fact that it is. Asbestos is naturally occurring and incredibly dangerous. "natural" has nothing to do with risk to human life.
- chrisseaton 6y ago> "natural" has nothing to do with risk to human life. Not sure who you think you're disagreeing with? Nobody said otherwise if you read the thread.
- XorNot 6y agoThen I have no idea it was necessary to talk about the "naturalness" of radioactive sources at all given the subject matter.
- consp 6y agoI usually give the "natural" qualification if it is not immediately obvious there are plenty of naturally occuring sources of radioactivity around us. This has mostly to so with human perception of radioactivity being something unnatural, maybe it was not necessary on HN. It does not matter that much in the end with respect to radioactivity.
