    The thing you said that someone disagreed with was calling it ionizing radiation, which is a more general term and describes radiation with enough energy to ionize an atom or molecule, which means stripping off at least one of its electrons. That requires a lot less energy than activating nuclei in an element that is not radioactive to radioactivity. UV light and X-rays are both ionising radiation, but are not from radioactivity and cannot induce radioactivity. Of course a lot of radioactive radiation (α, β, γ) is also too low-energy to activate more nuclei. It depends on the energy of the radiation and the specific element you’re trying to activate (how close it is to being radioactive, so to speak).

    So like CommissarVulpin said - the real danger is more likely to be contamination





  • That’s exactly what I mean, though. All these wars happen even though they aren’t profitable, so I don’t see how that’s relevant.

    Not saying politics can’t change for the worse, just that I haven’t seen voting, etc. change it for the better in a long time. It used to and I think peaceful protests and activism could help, just saying it’s not very visible as helpful right now.

    I don’t even see how you ended up getting into a tirade about vandalising from this post, especially if you agree that attacking billionaires directly has a chance of helping - isn’t that exactly what the cartoon shows?

    I agree with you that riots and vandalising aren’t currently helping - but I also don’t see them as a prevailing problem. Where is this currently going on? Most of what I see are peaceful protests with limited coverage and even more limited consequences

    I would really love an example for a war that didn’t happen because it wasn’t profitable, or a relevant leader toppled by social media. We live in a world where there aren’t any politicians we can vote for to actually lead to any change, and wars are closer to many of us than they have been in a long time, both physically and through the visibility of social media and globalisation. If there’s a peaceful way to stop this that you’re aware of, please do enlighten us
