A general rule of thumb is that if something is glowing blue or has a blue halo around it, you should run in the opposite direction.
Unless you saw it from really close, in which case it's too late and you should probably relax, sit down, have a drink, call your loved ones...
- toolsmax 1mo agoIn that case, I'm afraid your phone possibly won't function
- rbanffy 1mo agoWell… it might be a Nokia 2260
- delecti 1mo agoOr unless it's in water, in which case you're actually probably fine.
- rbanffy 1mo agoIf you swim too close to it, you might as well not bother to surface.
- delecti 1mo agoYes, "too" close by definition would be a problem. But even a meter of water between you and the source absorbs 99.994% of the radiation (down to 6 thousandths of a percent vs in air, or by a factor of about 1/16000).
- rbanffy 1mo agoIf the source is 16000x the exposure needed to kill you, then 1m will be too close.
- xattt 1mo agoShort of LINAC irradiator ride-through videos on YouTube, are there any photos of this effect in air from a point source?
- lazide 1mo agoAll the ones I see are reactors through water shielding, in which case you’d be fine. If you see a noticeable cherenkov effect from something that close that wasn’t heavily shielded by something like water, your camera sensor will likely be destroyed and you’d be dead pretty soon.
