    I see the stylisric reason to only apply the effect around the object, but it isn’t realistic.
    That radiation isn’t affected by optics, it’ll go right through the lenses that flip and focus the image and the aperture that might be engaged, and will hit the entire sensor equally. The entire image should be that noisy.

      Oh cool

      So if you had a camera with mirror would it still go a bit through the enclosure and hit the sensor?

      What if the sensor is flipped so it has to go through the silicon substrate before hitting the sensitive bits, would it be equally noisy but less noisy overall?

        Yes. Silicon substrate is too thin to matter. Redirecting with mirrors is probably gonna make it worse. Your housing would need over a cm of solid plastic to block beta radiation. On a dedicated camera you might have a sizeable lens with many lenses totalling a cm of shielding, but redirect the light and place the sensor not behind the lens and you only have that camera housing.

        Realistically though you have a smartphone, and that β-radiation will probably make it most of the way through the entire thing.

        And the gamma radiation really won’t care, even if you have a 50cm long zoom lens right between the sensor and source.
        This is where you might want a lead brick wall, 10cm thick should make it short-term safe for ⁶⁰Co.

        Edit: forgot this was in general, not about the β

        The beta emission of ⁶⁰Co can probably get through over 6mm of glass. This should be plenty for phones.

        But also

        ⁶⁰Co undergoes beta decay to an excited state of the stable isotope nickel-60 (⁶⁰Ni), which then emits two gamma rays […]

          Shouldn’t be allowed to exist. This removes the terror and fear of seeing an actual Co-60 rod and may kill someone.

    I highly recommend holding it within 3 feet of your body for 5 to 10 minutes; absolutely nothing can go wrong from holding a Cobalt-60 source with 3540 Curies in 1963 within 3 feet of your body for 5 to 10 minutes!

Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren’t unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don’t rush mod actions. If a case doesn’t need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.
