Ha! That’s exactly what came to mind for me too.

Ty!

Wait, why didn’t they get the bends?

The paper (which is very short) said 500-700nm and referenced an older (1997) paper that reported on a bunch of UV and visual emitting living systems. I looked there but didn’t pinpoint an answer. It did mention that the emission doesn’t usually have sharp peaks (as the reason they trade spectral resolution for sensitivity). It seems like the emitting molecules are large, so it’s probably pretty broad.

Anyway… that made me nice and sleepy.

I want to know at what wavelengths. Did I miss it?

It bugs me that they say ‘it’s not infrared - it’s photons!’ (paraphrasing).

lead poisoning becomes evident pretty early though doesn’t it? (With respect to kids)

I would think that the ratio of persistent exposure to unsafe level has got to be easily higher in cases like Flint than any fluoride-in-the-water usage. Just speculation on my part.

What measures are taken to avoid screwing up the dosage, anyone know? Maybe predilute so that an oops requires multiple buckets instead of vials?
