It seems more likely the OPs' problem is a rare, but permanent electronics failure unrelated to ionizing radiation.
I struggle to understand how only Kodak CCD photo-diode array technology is susceptible to irreversible cosmic-ray damage.
Cosmic ray damage to solid-state electronics is reversible. There are called soft failures. The most common effects occur in sold-state memory. Soft failures are highly angle dependent. There may be one known example were an aircraft experienced a temporary data system failure due to soft cosmic ray induced memory error.
The energy required for permanent failure involves rather high levels of exposure... high enough to kill you. Cosmic rays have extremely high energies, but the effective exposure time is extremely short. The total energy exposure is low.
For CCDs soft cosmic ray effects are reversible (see section 3.4 here
. CCDs are used to detect cosmic rays (link
) and a new CCD assembly is not required for each measurement.
CMOS sensors are also sensitive to cosmic rays as well
. Again, the effects are reversible.
