I am dubious radiation could be the explanation here. If anything, solar storms should cause a reduction in galactic cosmic radiation ("Forbush Decrease"), which would reduce radiation at the surface, not increase it.
They should analyze devices at higher elevation or higher latitude, where radiation effects from solar protons would be more important. Also, they should consider the effect on IoT devices of voltage fluctuations on the grid.
