APV: avian poxvirus, PI3: parainfluenza virus type 3, IBR: infectious bovine rhinotracheitis, BVDV: bovine viral diarrhea virus, BEFV: bovine ephemeral fever virus.

^*A kilobase (kb) pair is a unit of genome size measurement equal to 1,000 base pairs of DNA or RNA.

^aViruses in bovine serum.

^bViruses spiked into fetal bovine serum.

^clog₁₀ reduction per kGy represents the slope of the viral inactivation (log₁₀ reduction in titer) vs radiation dose in kGy.
