In his article he refers to a snapshot (look below) he made from a website of the Center for global environmental research. It shows how the different kind of UV-Radiation ought to be filtered by the atmosphere if the atmosphere would be healthy as it used to be.
No UV-C radiation ought to reach the ground.
The results of a metering expert show quite the opposite:
"(...) Current testing reveals that almost 70% of incoming UV radiation is currently in the UVB and UVC range. (Not 5% or less, as we are being told by all major agencies and their media mouthpieces).
This translates into nearly a 1,400% increase in UVB as a percentage of total UV. If UVA has also gone up due to the same ozone destruction which has driven up the UVB, this would indicate a likelihood that the total UVB and UVC is higher still - not just a difference of ratio with the same overall number.

The metering performed in Northern California, on which this statement is based, was done by a pair of identical state-of-the-art, brand-new, science-grade meters guaranteed to be scientifically calibrated to a range within 4%. As stated earlier in this article, the tech who did this metering is a 40- year veteran in environmental measurement and interpretation.
