The discussions reflect a nuanced debate, with some posts emphasizing the potential dangers of 222nm UVC, citing specific findings about skin damage and DNA effects, while others question safety measures and underlying assumptions, as seen in remarks about oxidative stress and filtration techniques. The tone varies from cautious to skeptical, illustrating active engagement with the scientific implications of the research.
AgreementNeither agree nor disagree
Discussions reveal conflicting opinions about the safety of 222-nm UVC, with some agreeing that caution is needed while others question its safety claims.
InterestHigh interest
Participants demonstrate high curiosity, referencing multiple studies, safety concerns, and technical details about the UVC sources.
EngagementModerate engagement
The conversations show moderate engagement with questions about methodology, safety filters, and physiological effects, indicating active consideration.
ImpactModerate impact
The debates about safety standards, potential risks, and differing study conclusions suggest some influence on safety perceptions but not a widespread paradigm shift.
Abstract in brief
This study investigated whether a 222nm UVC light, commonly used for sterilization, is safe for human skin by testing its effects on healthy volunteers.
Results showed that even at low doses, the 222nm UVC could cause skin redness and DNA damage, specifically in the basal cell layer, suggesting it can harm skin before reaching sterilization levels.
While 222nm UVC is promising as a less irritating sterilization method, its potential to cause skin damage highlights the need for careful dose management and safety assessments.
In the following study by Woods et al. a Sterilray emitter was used:

@judegomila @RajBhakta One paper claims an absorption depth issue, rather than reflectivity, to be the cause.

Seems to contradict the safety on skin (not sure what to make of it)

@FarUV_Sterilray @mas44022884 When comparing Sterilray and Ushio's 222nm UVC, there is clearly a big difference in whether or not it produces erythema.
Do you use a band-pass filter to remove the harmful wavelengths?
This is all for safety reasons.

@joeyfox85 Interesting given the conclusion of Woods' work was "The source showed an erythemogenic or CPD potential at lower doses than those required to reach the reported threshold bacteriostatic effect." when using the Steril-Ray. Filtered 222nm didn't show that.

@GainOfDystopia @ModelAyshaMirza 222 nm is also not necessarily safe for human exposure. Moreover, the Nature paper you referenced was going by the limit set by American Hygienists and not OSHA or the CDC. Moreover, that paper didn't investigate oxidative stress caused by Ozone at 222 nm https://t.co/sb3oxwfFvu
