The ozone layer that screens UV is above aircraft altitudes.
Most glass also screens UV. So, UV is not an onboard risk.
UVA and UVB are broad bands. The solar spectrum is a blackbody at ~6000K, so UV light from the Sun is fading quickly shortwards of blue light to the ~310nm atmospheric cutoff.
You need to worry about UV on the ground, not onboard.
Follow the Australian advice on the matter.
Aircrew are subject to enhanced cosmic ray radiation, at polar latitudes, at high altitudes and during solar storms. I understand that Concorde crews were licensed radiation workers.
