@manawyrm @q @ryanc @vidister Yeah, also it really depends on what part is exposed etc, for example eyes can get damage from intense blue light from a similar mechanism, as far as I know that causes some light-sensing chemical to react and too intense light can basically overload the regeneration of that or so (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9938358/ "When light exposure is longer or more intense, all-trans-retinal accumulates and its activation by blue light can cause oxidative stress that damages the cellular components of the outer segment of the photoreceptors."), or when one gets photosensitive chemicals (specifically polymerization initiators but also some other things) in their skin then even 400 nm light can cause damage.

Blue Light Exposure: Ocular Hazards and Prevention—A Narrative Review

Exposure to blue light has seriously increased in our environment since the arrival of light emitting diodes (LEDs) and, in recent years, the proliferation of digital devices rich in blue light. This raises some questions about its potential deleterious ...

@manawyrm @q @ryanc @vidister (Yes its gonna hurt you, but not by means of ionization)

@manawyrm @q @ryanc @vidister Ionizing to what exactly?

@manawyrm @q @ryanc @vidister The ionizing ones will be attenuated within millimeters if this graph is correct https://www.researchgate.net/figure/Upper-plot-Attenuation-length-of-the-VUV-light-in-air-these-values-were-calculated_fig24_334825561 (assuming it continues like that below 80 nm)
