I’m thinking a big flaming nuclear fusion reactor creates more power than some lamp
Honestly I have no idea how the intensity compares but I’m just saying without numbers you can’t really compare it to a lamp. Especially if that lamp assumes that some person might put their hand under it.
I am not the one who made the initial claim, but if you want numbers: about 2 % of sunlight is a shorter wavelength than UV-B or about 70 W/m². If you want the same irradiance from a lamp, all you need to do is get closer, unless the lamp is really weak. 5 seconds is simply nothing.
I didn’t mean to make any claim, lol, 5 seconds would be nothing and I’m trying to be funny in the vain it no O2 being not a big deal at 5 seconds.
We had an ozone crisis before, although it is serious if it’s something closer to an hour. People got sunburned in 15 minutes quite easily, though, and skin cancer is linked to it.
The atmosphere does block a lot of cosmic ray junk, but that’s a collective effort. I forget the details, but think very high frequency gamma rays. But that’s not ozone alone.

Yeah that does seem fairly unproblematic, I have to concede
